R-E-Z. Differences between the QuickBasic 4.50, BASIC 7.1 (PDS) and Visual Basic for DOS (VBDOS) versions are detailed. The documentation can be used for the unenhanced versions with the following exceptions. 1. MEMORY - Additional libraries are included in the enhanced versions which do not contain error checking or window status capability. These libraries can be used after the program is de-bugged and represent an opportunity for considerable memory reduction. - Additional libraries are included in the enhanced versions which can be used for programs not requiring event handling. The libraries in the unenhanced versions allow event handling. Extra libraries for programs not requiring event handling are not included in the unenhanced versions. Modules compiled from the QB/QBX/VBDOS environment will use the event handing switches ( /W or /V ) in the unenhanced versions even if event handling is not used. This produces larger and slower programs. 2. The BASIC 7.1 and VBDOS unenhanced versions do not allow the use of unnamed ( blank ) COMMON blocks. The enhanced version has provisions for the use of same. ********************************************************** ** For information on obtaining the enhanced version ** ** of WINDOWS R-E-Z see the file ORDER.ME. ** ********************************************************** 1 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Important notes for BASIC 7.1 and VBDOS 1.00 users. ENHANCED AND UNENHANCED VERSIONS: The /Ea option may be used when loading QBX or VBDOS. This allows the use of expanded memory. Window memory resides in a separate segment of string space reserved for strings placed in unnamed ( blank ) COMMON blocks. DO NOT USE BLANK COMMON BLOCKS IN YOUR PROGRAM. EXAMPLE: COMMON SHARED A$ ' NOT PERMITTED COMMON SHARED /BLOCKNAME/ A$ ' PERMITTED Maximum window memory is 64k bytes. Calls to MAKEWIND or SAVEWIND requesting window memory in excess of 64k bytes will result in an "Out of string space" error message. As 64k represents sixteen full display windows (80 x 25 mode) this limitation should not be restrictive. The use of far strings is required. This is the default for programs compiled from the QBX environment If the source code is compiled on the command line the /Fs option must be used with BC. Unlike BASIC 7.1, VBDOS always uses far strings. ENHANCED VERSION ONLY: Additional object files PDSALT.OBJ or VBALT.OBJ are included which allow the use of unnamed (blank) COMMON blocks. They must replace the object file PDSVBMEM.OBJ, which is included in the BASIC 7.1 and VB for DOS libraries. Window memory will share main module string space after this change is made. To make this change; 1. Make new library files.

With WINDOWS R-E-Z users can make, save, restore, and delete up to twenty windows. The memory used to save windowed areas is dynamically allocated and outside of basic's normal data storage area leaving more room for the basic programs data. Windows are assigned a number from zero to twenty. INPUT WINDOWS, MULTI-FIELD INPUT SCREENS, CHOICE WINDOWS, CHOICE BARS and GET ANSWER WINDOWS all provide an excellent source for user input. Input fields may be alpha/numeric, numeric, date or restricted. Multi-field input fields may be use to emulate "buttons". Additional numerous options are included for input fields. WINDOWS R-E-Z provides users the ability to incorporate "PULLDOWN WINDOWS", emulating those used in the QuickBASIC programming environment, in their programs. Directory routines find the default drive and path, disk size and free space, and directory listing for any path. File size, date, time, and attributes can also be found. Information line routines provide an easy means to print messages, directions, or prompts, anyplace on the display. SCROLL WINDOWS may be used to scroll through small lists or large databases. Also includes are numerous KEYBOARD and MOUSE routines. All of the routines require a minimal amount of initial- ization and the resulting programs present a professional appearance. Unlike many other basic "add-ons", WINDOWS R-E-Z provides extensive error detection and reporting. Procedures included: SETWIND -------- Set up routine for windowing procedures. MAKEWIND ------- Makes a window. Saves windowed area to window memory. The window becomes the "active window".

GETTING STARTED Before using the routines included in WINDOW R-E-Z, it is necessary to set several global values. The following routines set these values. These routines must be called at the start of any program. ROUTINE USED TO... SETWIND 1. Set the default sound for all routines 2. Set the shadow color for all windows. 3. Set "slow print" for CGA adaptors. 4. Determine how certain hi-intensity characters are displayed. 3. Set the color of button brackets ( < > ). SETWIND MUST BE CALLED BEFORE USING ANY OF THE ROUTINES INCLUDED WITH WINDOW R-E-Z. INPTINIT 1. Set the date format for input routines. 2. Set the comma designator for input routines. 3. Set the cursor "start position" for input routines. 4. Determine if the first valid key pressed erases an input field. 5. Determine if an invalid key produces a sound while entering data in an input field. INPTINIT MUST BE CALL PRIOR TO CALLING ROUTINES MULTINPT, INPTWIND, OR SCRLWIND, CHOICEWIND, OR CHOICEBAR. MOUSEON 1. Initializes the mouse and optionally turns the mouse "ON". MOUSEON MUST BE CALLED TO USE THE MOUSE SEE THE DETAILED DESCRIPTIONS FOR THE INDIVIDUAL ROUTINES. 10 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. USING WINDOWS R-E-Z THE ACTIVE WINDOW When a window is defined ( made ) the number assigned to it by the programmer represents the area covered by the window. The area is restored or deleted via it's "number". Up to 20 window areas can be saved. The memory used to save the window areas is automatically managed by WINDOWS R-E-Z. Any time a window is made it becomes the "active" window. The active window is used by the following routines. PRINTW --- Prints text in the active window. LINEW ---- Prints a line in the active window. BOXW ----- Prints a box in the active window. SCRLWIND - Places a scrollable list in the active window. CLRWIND -- Clears all text from the interior of the active window. RESAVE -- Saves the active window and any text in the active window. NEWCOLOR - Changes the "print-to" color of the active window. NOTE: ACTIVE INPUT AND PULLDOWN WINDOWS MAY ALSO EXIST. THESE WINDOWS ARE NOT RELATED TO THE ACTIVE WINDOW GENERATED BY THE WINDOWING ROUTINES. 1.00 SETWIND ( FST%, SND%, SHAD%, NOHI%, BRACKETATTR% ) Description: SETWIND must be called at least once in any program using the routines in WINDOWS-R-E-Z, prior to calling the routines. This procedure initializes window memory. It also sets the default windowing speed, sound, window shadow color, and "button" bracket color. The first call to SETWIND initializes window memory and sets the default parameters. Subsequent calls to SETWIND will not affect window memory but can be used to change the default parameters. NOTE: IF A CLEAR STATEMENT IS EXECUTED BY THE PROGRAM ALL WINDOW MEMORY IS LOST. WINDOW AREAS SAVED IN WINDOW MEMORY ARE LOST. SETWIND MUST BE CALLED AGAIN TO RE- INITIALIZE WINDOW MEMORY AFTER EXECUTING A CLEAR STATEMENT. Arguments: FST% is used to allow "fast" windowing if a CGA video card, or emulation, is detected. If FST% = 0 window routines will be slower on computers 11 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. with CGA. If FST% = 1 window routines will be "fast" on computers with CGA. This may, however, cause "snow" with certain CGA cards. If a monochrome, EGA, or VGA card is detected, FST% is ignored. All windowing is "fast". SND% determines which sound will be generated by the routines. If SND% = 1 a "CLICK" sound will be generated. If SND% = 2 a "BEEP" sound will be produced. Any other value produces no sound. SHAD% sets the color for window shad- ows. See the color attribute chart for details. Set- ting SHAD% to 7 works well for monochrome displays while setting SHAD% to 8 works well for color displays. NOHI% determines how pulldown and scroll window routines display "key" characters. It also determines how the button brackets ( < > ) for the active choice for routines SCRLWIND, INPTWIND, CHOICEBAR, and CHOICEWIND are displayed. In addition, if a field defined in routine MAKEFIELD is use to make a "button field" the color of characters used as brackets ( when the field is active via routine MULTINPT ) is affected by the value of NOHI% If NOHI% = 0 key characters or brackets are displayed in their specified color. If NOHI% = 1 "key" characters and brackets are displayed in reverse video. This is appropriate for LCD displays which can not display high intensity characters. NOHI% affects "key" characters and "active brackets" ONLY if they have been defined to have a different color then normal characters and inactive brackets. BRACKETATTR% determines the foreground color of button brackets ( < > ) for active choices or fields in routines SCRLWIND, INPTWIND, CHOICEWIND, CHOICEBAR, and MULTINPT. It only affects the brackets for the active choice. BRACKETATTR% may be set from 0 to 15. For most applications BRACKETATTR% can be set to 15 with good results. If BRACKETATTR% is set to zero the bracket color for the active choice does not change. The brackets retain their in-active color. 1.01 MAKEWIND (W%, LABEL$, TR%, LC%, WIDE%, NR%, ATTR%, BORBER%) Description: Makes a window. May also save a window- ed area to window memory. The window becomes the active window. Calls to PRINTW, LINEW, SCRLWIND, CLRWIND, BOXW, RESAVE, and NEWCOLOR refer to the active window. If an attempt is made to place a window on the display and it will not fit on the display an error will be reported. The 12 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. maximum size of a window is dependent on the screen mode when a window is made. NOTE: TEXT MODES 80x25, 80x43 AND 80x50 ARE SUPPORTED. Arguments: W% is the window number and must equal 0 to 20. If W% = 0 the area under the window is not saved. A window is simply made. If W% is from 1 to 20 the area under the window is saved and may be restored at a later time via a call to RSTRWIND. If W% is the number of a window area previously saved by MAKEWIND or SAVEWIND an error is reported. NOTE: WHEN WINDOW NUMBER 1 TO 20 IS MADE AN IMAGE OF THE DISPLAY AREA UNDER THE WINDOW IS SAVED IN WINDOW MEMORY. THIS AREA MAY BE RESTORED TO THE DISPLAY BY CALLING ROUTINE RSTRWIND. ROUTINE RSTRWIND MAY OPTIONALLY REMOVE THE "SAVED" DISPLAY AREA FROM WINDOW MEMORY. A SECOND ROUTINE, DELWIND, MAY BE USED TO REMOVE THE "SAVED" DISPLAY AREA FROM WINDOW MEMORY. THIS ROUTINE DOES NOT, HOWEVER, RESTORE THE "SAVED" DISPLAY AREA TO THE SCREEN. DO NOT CONFUSE THESE ROUTINES!! SEE THE DESCRIPTIONS FOR ROUTINES RSTRWIND AND DELWIND FOR DETAILS. LABEL$ is the text printed on the top border or in the title box (see BORDER%) of the window. By default the print starts on the second column. If the first character of LABEL$ ="@" the text will be centered. If LABEL$ is too long it will be truncated to fit on the top border or in the title box. TR% is the top row of the window. If TR% = 100 the window will be centered from top to bottom. LC% is the left column position of the win- dow. If LC% = 100 the window will be centered from left to right. WIDE% is the window's width. WIDE% must be greater than 2. WIDE% + LC% -1 must not be greater than 80. ( The displays width ). NR% is the number of rows in the window and must be greater than 2. NR% + TR% must not be greater than the display rows + 1 . If NR% is less than 5 a window title box is not permitted. ATTR% is the window's color and may be in the range of 0 to 255. The foreground ( window's label and border ) color equals ATTR% MOD 16. The background 13 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. color equals INT( ATTR% / 16 ). If the background color is greater than 7 the foreground flashes and the back- ground color equals background color - 8. If the fore- ground and background colors are the same the border and label will not be visible. ( SEE THE COLOR ATTRIBUTE CHART.) ATTR% becomes the print-to color for window W%. BORDER% sets the window's border and shadow and can be up to 3 digits in length. DIGIT = #3 #2 #1 Example = 1 1 1 ( 111 ) Digit #1 sets the border. 0 = No border 1 = Single line border 2 = Double line border Digit #2 sets the shadow. 0 = No shadow 1 = Right/Bottom shadow 2 = Left/Bottom shadow 3 = Left/Top shadow 4 = Right/top Shadow Digit #3 set the title box. 0 = No title box 1 = title box The example (111) has a 1 for each digit. The window will have a single lined border, a shadow on the right and bottom and a title box NOTE: IF BORDER% IS 100 OR GREATER AND THE NUMBER OF ROWS (NR%) IS LESS THAN 5 TITLE BOXES ARE NOT PERMITTED. SEE THE BORDER DESIGNATION CHART IN THE APPENDIX FOR FURTHER DETAILS. 1.02 CHNGWIND (W%) Description: Makes window, W%, the active window. W% must represent a window area in window memory. Argument: W% is the window number. It must range from 0 to 20. If W% does not represent a window saved by a previous call to MAKEWIND, CHNGWIND reports an error. NOTE: W% CAN NOT REPRESENT A WINDOW SAVED BY "SAVEWIND". IT MUST REPRESENT A WINDOW SAVED BY "MAKEWIND". 14 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 1.03 PRINTW (TEXT$, R%, LC%) Description: Prints text to the active window. Care must be used to assure the active window is visible as PRINTW will print predicated on the coordinates of the active window regardless of it's visibility. It is advisable, therefore, to print to a window immediately after it is made the active window. The text's color will be the print-to color of the active window. If no window is active when PRINTW is called an error will be reported. Arguments: TEXT$ is the text to be printed. R% is the row in the window were the text will print . If R%=1 the text will print in the first row below the border or title box. PRINTW may be used to print a label in the bottom border of the window by setting R% to the number or rows in the active window minus 1 ( minus 3 if a title box was specified ). An invalid value for R% will result in a reported error. LC% is the left column where TEXT$ starts printing. If LC%=100 the text will be centered left to right. IF LC% plus the length of TEXT$ is greater than the windows width minus 2 an error will be reported. 1.04 PRINTWHOT ( TEXT$, R%, LC%, HOTCHARPOS%, HOTATTR% ) Description: Prints text to the active window. Prints one character ( the "hot character" ) in a different color. Care must be used to assure the active window is visible as PRINTWHOT will print predicated on the coordinates of the active window regardless of it's visibility. It is advisable therefore, to print to a window immediately after it is made the active window. The text's color ( excluding the "hot character" ) will be the print-to color of the active window. If no window is active when PRINTWHOT is called an error will be reported. Arguments: TEXT$ is the text to be printed. R% is the row in the window were the text will print . If R%=1 the text will print in the first row below the border or title box. PRINTW may be used to print a label in the bottom border of the window by setting R% to the number or rows in the active window minus 1 ( minus 3 if a title box was specified ). An invalid value for R% will result in a reported error. LC% is the left column where TEXT$ starts printing. If LC%=100 the text will be centered left to 15 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. right. IF LC% plus the length of TEXT$ is greater than the windows width minus 2 an error will be reported. HOTCHARPOS% is the position in TEXT$ of the "hot character". HOTATTR% is the color or the "hot character". ( SEE THE COLOR ATTRIBUTE CHART IN THE APPENDIX. ) 1.05 SAVEWIND (W%, TR%, LC%, WIDE%, NR%) Description: Saves a portion of the screen in window memory. This procedure is the same as MAKEWIND except no window is made. The area designated by the arguments is saved. If the number assigned to W% represents a window area previously saved by MAKEWIND or SAVEWIND an error is reported. An area saved via SAVEWIND can be "popped" to the screen at appropriate times during program execution by RSTRWIND ( see description ). A screen area saved by SAVEWIND DOES NOT BECOME THE ACTIVE WINDOW. SAVEWIND differs from RESAVE in that it saves an area of the screen specified by it's arguments. RESAVE saves the area of the screen as designated by the coordinates of the active window. Arguments: W% must range from 1 to 20. See MAKEWIND for a description of the remaining arguments. 1.06 RESAVE Description: Saves the active window, it's interior, and shadow. As window number 0 can not be saved the active window can not be window number 0. If there is no active window or window number 0 is active when RESAVE is called an error will be reported. The screen area saved under the active window is removed from window memory and replaced with the active window and it's interior. After complex screens are made in the active window's interior, RESAVE can be used to save them. They can be restored to the screen using RSTRWIND. Use RESAVE immediately after a window is made and it's interior is filled as RESAVE will save the area of the screen determined by the active window's coordinates, even if it is not visible. 16 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Use RESAVE as follows; 1. Make a window number 1 to 20 via a call to MAKEWIND. This becomes the active window. 2. Print in the window using PRINTW, LINEW, or BOXW. 3. Call CHNGWIND to make the window number used in step 1 the active window. ( Only required if additional windows were made inside the original window. ) 4. Call RESAVE to save active window. 5. Use RSTRWIND to "pop" the window and it's interior on the screen any time during program execution. 6. After the window is restored to the screen it may be printed in again provided it is the active window. This may require a call to CHNGWIND. Arguments: None. 1.07 RSTRWIND (W%, DELFLAG%) Description: Restores a window are previously saved by MAKEWIND, SAVEWIND or RESAVE. The window area (W%) must exist in window memory or RSTRWIND does nothing. NOTE: WHEN A WINDOW IS RESTORED IT IS THE PROGRAMMER'S RESPONSIBILITY TO ASSURE THE SCREEN MODE IS THE SAME AS IT WAS WHEN IT WAS MADE. IF A WINDOW IS MADE IN THE 43 ROW SCREEN MODE IT MUST BE RESTORED IN SAME. Arguments: W% is the number ( 1 to 20 ) assigned to the saved window area to be restored to the screen. The window area is returned to it's original coordinates. DELFLAG% is set to zero to keep the windowed area in window memory. If the DELFLAG% is not zero the saved window area (W%) is deleted from window memory. If W% was the active window an active window will no longer exist. 1.08 DELWIND (W%) Description: Deletes a saved window area (W%) from window memory, if it exists in window memory. If the window is the active window an active window will no longer exist. 17 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. NOTE: DELWIND DOES NOT RESTORE THE "SAVED" WINDOW AREA TO THE DISPLAY. IT ONLY REMOVES THE "SAVED" WINDOW AREA FROM WINDOW MEMORY. ROUTINE RSTRWIND MUST BE USED TO RESTORE THE "SAVED" WINDOW AREA TO THE DISPLAY. Argument: W% is the window area number. 1.09 CLRWIND Description: Clears the interior of the active window. Care must be taken to assure that active window is visible as CLRWIND clears the area of the screen designated as the interior of the active window regard- less of the window's visibility. The window will be cleared with it's print-to color. If no window is active when CLRWIND is called, an error is reported. Arguments: None 1.10 NEWCOLOR ( ATTR% ) Description: Changes the print-to color of the active window. Text printed in the window by PRINTW, lines printed in the window by LINEW, and boxes printed by BOXW will assume the new color specified by this routine. If the active window is cleared via a call to CLRWIND, it's interior will be cleared with the color specified by NEWCOLOR. The color designation will be retained and used by subsequent calls to PRINTW or LINEW for the window which was active when NEWCOLOR was called. If no window is active when NEWCOLOR is called, an error is reported. Argument: ATTR% is the new color attribute. SEE THE COLOR ATTRIBUTE CHART IN THE APPENDIX. 1.11 LINEW ( ROW%, TYP% ) Description: Prints, or erases a line in the active window. If an active window does not exist an error is reported. The line will assume the print-to color of the active window. As the border characters are changed when a line is printed, the color of the border characters may change also. This will occur if the print-to color is not the same as the color of the border characters in the active window. Arguments: ROW% is the row, of the interior, of the active window where a line will print. If ROW% < 1 or ROW% greater then the number of rows in the interior of the active window an error will be reported. 18 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. TYP% is the type of line which will print and may be as follows; TYP% Line type 1 Single line 2 Double line 0 Erases a line and returns normal border characters. Other values Defaults to single line. NOTE: IF TYP% = 0 ANY TEXT ON LINE ( ROW% ) IN THE WINDOW WILL BE ERASED. 1.12 BOXW ( TR%, LC%, WD%, NR%, BORDER% ) Description: Draws a box in the active window. The box is drawn in the "print-to" color. If an attempt is make to make a box that will not fit entirely within the active window an error will be reported. An active window must exist or an error will be reported. Arguments: TR% is the top row of the box relative to the active window's top interior row. LC% is the left column position of the box relative to the active window's left border. WD% specifies the boxes width. NR% specifies the number of rows for the box. BORDER% sets the boxes border and may be set as follows. BORDER% Border 0 no border - may be used to erase an existing box. 1 single line border. 2 double line border. Other values default to BORDER% = 1. 19 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 1.13 WAVAIL% ( WINDNUM% ) Description: WAVAIL% is a function. It determines if a window is available. A window is available if it has never been used or if it has been used and subsequently deleted by routines RSTRWIND or DELWIND. AS WAVAIL% IS A FUNCTION IT IS IMPERATIVE IT IS DECLARED IN ANY MODULE USING IT. WAVAIL% equals 1 if a window is available. WAVAIL% equals 0 if a window is not available. Argument: WINDNUM% is the window number. It may range from 1 to 25. Windows 1 to 20 are used in the window management system. Window 22 is used for the get answer window in routine GETANS. The following applies to windows 21, 23, 24, AND 25. WINDOW# WAVAIL% MEANING = 21 0 There is an active input window. It may be deleted by routine RSTRINPT. A call to INPTWIND re-enters the active input window. 21 1 There is no active input window. Calling INPTWIND will make a new active input window. 23 0 There is an active pulldown window. It may be deleted by routine RSTRPULL. A call to PULLDOWN re-enters the active pulldown window. 23 1 There is no active pulldown window. Calling PULLDOWN will place the user at the first selection of the pulldown menubar. 24 0 There is an active pulldown menubar. It may be deleted by routine RSTRPULL. A call to pulldown will not save the display area occupied by the menubar. 24 1 There is no active pulldown menubar. Calling PULLDOWN will make an active menubar and save the display area occupied by same. 25 0 There is an active info-line. It may be deleted by routine RSTRINFO. Calls to PRINTINFO will print in the info- line. 25 1 There is no active info-line. Calling INFOLINE will make an active info-line 20 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 1.14 WINDSTATUS Description: This is a programming tool. Calling WINDSTATUS reports window 0 to 20's. number, top row, left column, width, number of rows, and attribute (color). The attribute refers to the original attribute specified by the call to MAKEWIND for each window. If the attribute is "SAVED" the window area was saved by a call to SAVEWIND, not MAKEWIND. WINDSTATUS also reports the active window and total window memory used to save window areas. Window number zero does not use window memory as the area under it is not saved. To use WINDSTATUS place a call to WINDSTATUS in the program at the location where it is desirable to view each windows parameters. The program will terminate and must be restarted. First remove the call to WINDSTATUS. NOTE: IF A WINDOW HAS A SHADOW IT'S WIDTH IS INCREASED BY TWO AND IT'S LENGTH IS INCREASED BY ONE. Arguments: None. 21 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ***** PULLDOWN WINDOWS ***** These procedures generate a maximum of 10 pulldown windows. The area covered by the pulldown windows is saved and restored as the window moves from one menubar item to the next. To select a menubar item the ARROW keys can be used or the first letter of the menubar item may be pressed. To select an item from any of the pulldown windows the ARROW keys, or "KEY CHARACTER" for the item may be pressed. If the ARROW keys are used the ENTER or RETURN key must be pressed to finalize the selection. If a letter is pressed, and it is found, the procedure is automatically exited without the need to press the ENTER or RETURN keys. The ESC and FUNCTION keys may optionally exit. 2.00 SETPULL ( TR%, LC% , WD%, PWIND$() ) Description: Must be called to set up the routine PULLDOWN. Must be called prior to calling routines PULLDOWN or CHNGPULL. Arguments: TR% is the top row position of the menubar. If the top row position of the menubar is set too low not allowing a pulldown window to fit on the display an error will be reported ( WINDOW WON'T FIT or SHADOW WON'T FIT ) when the pulldown window is accessed. LC% is the left column position of the menubar. It must range from 1 to 73. If the left column position of the menubar is set too high not allowing a pulldown window to fit on the display an error will be reported ( WINDOW WON'T FIT or SHADOW WON'T FIT ) when the pulldown window is accessed. WD% is the width of the menubar. WD% is self adjusting if it is set outside of the permissible range. The maximum width of the menubar is 81 - LC%. The minimum width of the menubar equals the width of the individuals items in the menubar plus two spaces between each item plus two preceding spaces and one trailing space. If WD% is set too low it self adjusts to the minimum width. If it is set too high it self adjusts to the maximum width. WD% only changes the length, by adding trailing spaces to the menubar, if it is greater then the minimum width and less then or equal to the maximum width of the menubar. PWIND$() is an array containing strings representing menubar selections, the data for the info- line for the menubar selections, and the individual 22 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. pulldown window selections. PWIND$() must be in the correct format. The last selection in each pulldown window must be followed by a "***" in PWIND$(). "ENDPULL" in PWIND$() marks the end of all pulldown windows. PWIND$(1) must be the first string in the array, NOT PWIND$(0). The following represents an example of the required format for PWIND$() for a pulldown window ( the first pulldown window ). EXAMPLE: PWIND$(1) = "File" ' Menubar selection for ( SEE BELOW ) ' pulldown window one. PWIND$(2) = "File operations" ' This will print in NOTE: MUST = "" IF INFO-LINE ' the info-line for IS NOT USED. ' menubar selection 1 PWIND$(3) = "Save" ' Selections for the PWIND$(4) = "Get" ' pulldown window. PWIND$(5) = "Delete" PWIND$(6) = "***" ' End of pulldown ' window. PWIND(7) = ........ ' Start over for next ' pulldown window. PWIND(?? - 1) = "***" ' End of last pulldown ' window. PWIND(??) = "ENDPULL" ' End of all pulldown data. In the above example PWIND$(1) holds the menubar selection for the first pulldown window. The menubar defaults to two spaces between selections. If PWIND$(1) = "File " two additions spaces will be inserted between "File" and the next menubar selection. Only trailing spaces are considered. Leading spaces are removed. PWIND$(2) holds the data for the info-line ( SEE ROUTINE INFOLINE ) for the first menubar selection, "File". For every menubar selection in PWIND$() the following element of PWIND$() MUST contain info-line data. If an info-line is not used set the appropriate elements of PWIND$ to equal "". Pulldown window selections follow the info-line data in PWIND$(). Each element of PWIND$() which represents a pulldown window selection has a "KEY CHARACTER". The key character is the character which is searched for when a key is pressed while in the PULLDOWN window environment. The key character defaults to the first character in each item. To designate the key character as a different character follow the character with a "@". THIS IS ONLY 23 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. APPLICABLE TO THE PULLDOWN WINDOW SELECTIONS. THE PULLDOWN MENUBAR SELECTIONS ALWAYS DEFAULT TO THE FIRST CHARACTER. IF A "@" IS PLACED IN A MENUBAR STRING IT WILL PRINT AS PART OF THE MENUBAR. EXAMPLES: PWIND$(3) = "Get File" ( Key character = "G") PWIND$(4) = "Save F@ile" ( Key character = "F") The "@" will not be displayed when the string is printed in the pulldown window. The description for KEYATTR% for the routine PULLDOWN describes how to make the key character a different color, or high intensity, enabling users to distinguish it as the key character. NOTE: DO NOT PLACE THE "@" IN POSITION ONE OR TWO OF THE STRING AS IT WILL PRINT IN THE PULLDOWN WINDOW. AS STATED THE KEY CHARACTER WILL DEFAULT TO POSITION ONE IF THE "@" IS OMITTED FROM THE STRING. THIS ELIMINATES THE NEED TO PLACE THE "@" IN POSITION TWO. If an element of PWIND$() = "-" and it is not the first or last item in a pulldown window it will segment the pulldown window by placing a line across the width of it. If the "-" is the first or last item in the pulldown window it will print as a "-". EXAMPLE: PWIND$(4) = "-" Providing PWIND$(4) is not last item in the pulldown window PWIND$(4) will print as a line across the window. -------------------------------------------------------- EXAMPLE: SETPULL N%=30 ' USE THIS METHOD SO DIM PWIND$(N%) ' PWIND$() IS DYNAMIC.

This is only a temporary array to hold the data and is erased after SETPULL is called. The data is then read. The "***" signals the end of each pulldown window and MUST be entered exactly as shown. The "ENDPULL" signals the end for all pulldown windows and MUST be the last data item read. If the format is not exactly as shown an error will be reported or the windows will not be as expected. In the example shown the first menubar item is "THIS". It's associated pulldown window contains the two items "HELLO" and "JOE". When "THIS" is selected the info-line, if it is on, will display "Sample window 1". The last menubar item is "SAMPLE" and it's pulldown window contains one item "BYE". When "SAMPLE" is selected the info-line will display "Sample window 3". The menubar is located on line 1, column 1 ( TR%=1 and LC% = 1 ). It occupies the entire row as WD% = 80. NOTE: THE DATA MUST BE IN THE FORMAT SHOWN. THE CHAR- ACTERS "***" MARK THE END OF EACH INDIVIDUAL WINDOW AND THE WORD "ENDPULL" MARKS THE END OF ALL PULLDOWN WINDOWS. 2.01 PULLDOWN (INFO$(),BAR%,WIND%,EX$,RKEY%,ATTR%,KEYATTR%,BRDR%) NOTE 1: ROUTINE "SETPULL" MUST BE CALLED ONCE PRIOR TO CALLING THIS ROUTINE. NOTE 2: ROUTINE "RSTRPULL" MUST BE CALLED AFTER THIS ROUTINE IS EXITED TO DEACTIVATE THE ACTIVE PULLDOWN WINDOW AND RESTORE THE DISPLAY AREAS UNDER THE ACTIVE PULLDOWN WINDOW AND MENUBAR. IF "RSTRPULL" IS NOT CALLED THE ACTIVE PULLDOWN WINDOW AND MENUBAR REMAIN ACTIVE. ( *** SEE RSTRPULL *** ) Description: Places the user in the pulldown window 25 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. environment. On entering PULLDOWN, the following occurs. 1. IF AN ACTIVE PULLDOWN WINDOW DOES NOT EXIST the scroll bar will be positioned over first selection in the pulldown menubar. 2. IF AN ACTIVE PULLDOWN WINDOW EXISTS the scroll bar will be positioned over the active pulldown selection in the active pulldown window ( SEE RSTRPULL ). This may be appropriate if a selection from a pulldown window is used to present the user with selections from another scroll window external to PULLDOWN. If the user presses ESC to exit the external scroll window PULLDOWN may be re-entered exactly where it was exited. IN THIS CASE THE ACTIVE PULLDOWN WINDOW MUST BE INTACT. IT WILL NOT BE COMPLETELY RE-PRINTED. If the user makes a selection from the external scroll window, the routine RSTRPULL may be used to restore the area under the pulldown window and deactivate the active pulldown window. The next call to PULLDOWN displays the pulldown menubar with the scroll bar positioned over the first item. IF AN ACTIVE PULLDOWN WINDOW UNKNOWINGLY EXISTS ON ENTRY TO PULLDOWN THE ACTIVE PULLDOWN WINDOW, IF NOT DISPLAYED, WILL HAVE IT'S INTERIOR PARTIALLY REPRINTED. THE WINDOW WILL NOT BE RE-PRINTED. Arguments: INFO$() is a string array holding the data for the info-line ( SEE ROUTINE INFOLINE ) for each pulldown windows's selections. Do not confuse this with the info-line data which is associated with the menubar selections as defined in routine SETPULL. The info-line provides instructions or descriptions for the selections in the pulldown windows. If pulldown window one holds five selections, INFO$(1) holds the data for the first selection in the window. INFO$(2) is the data for the second selection. Corresponding elements of INFO$() and the pulldown window's selections are related. A SEGMENTING LINE IN A PULLDOWN WINDOW MUST BE REPRESENTED BY A "" IN INFO$(). If pulldown window one contains five selections and pulldown window two contains ten selections, INFO$(6) will hold the data for the info- line for the first selection in the pulldown window two while INFO$(15) will hold the data for the info-line for the last selection. The elements of INFO$() will only be displayed in the info-line if it is "turned on" via routine INFOLINE. IF AN INFO-LINE IS NOT USED INFO$() MUST STILL BE A PREVIOUSLY DIMENSION ARRAY. DIMENSION INFO$() TO ZERO BEFORE CALLING PULLDOWN. EXAMPLE: DIM INFO$(0) 'IF INFO-LINE IS NOT USED 26 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Using the example for the pulldown windows defined in the call to SETPULL ( SEE - EXAMPLE: SETPULL ) the following could apply to INFO$() EXAMPLE: DIM INFO$(10) ' DO NOT ERASE THIS ARRAY!!! INFO$() ' RELATED PULLDOWN SELECTION ---------------------------------------------------- INFO$(1) = "ONE" ' WINDOW 1 SELECTION "HELLO" INFO$(2) = "TWO" ' WINDOW 1 SELECTION "JOE" INFO$(3) = "THREE" ' WINDOW 2 SELECTION "HOW" INFO$(4) = "FOUR" ' WINDOW 2 SELECTION "ARE" INFO$(5) = "" ' WINDOW 2 -- LINE INFO$(6) = "FIVE" ' WINDOW 2 SELECTION "YOU" INFO$(7) = "SIX" ' WINDOW 3 SELECTION "I" INFO$(8) = "SEVEN" ' WINDOW 3 SELECTION "AM" INFO$(9) = "EIGHT" ' WINDOW 3 SELECTION "FINE" INFO$(10) = "NINE" ' WINDOW 4 SELECTION "BYE" The numbers ONE, TWO, THREE .... will print in the info-line when the corresponding pulldown window selection is covered by the scroll bar. BAR% is the sequential number (left to right) of selected menubar item . It is returned by the calling procedure, PULLDOWN. If the second item in the menubar is selected, BAR% will equal two. If ESC is pressed and ESC is an exit key BAR% will equal 0 on exit. If a function key is pressed and it is an exit key, BAR% will equal the highlighted menubar selection on exit. WIND% represents the row number of the selected pulldown window item. It is returned by the calling procedure. If the ESC pressed and ESC is an exit key, WIND% will equal 0 on exit. If a function key is pressed and it is an exit key, WIND% will equal the highlighted pulldown window selection ( interior row number ) on exit. NOTE: A SEGMENTING LINE IN A PULLDOWN WINDOW OCCUPIES A ROW POSITION. EX$ sets the keys which will, when pressed, exit PULLDOWN. The ENTER ( RETURN ) key always exits. EX$ can be used to simulate a selection from a pulldown window. ( SEE DESCRIPTION FOR ARGUMENT RKEY% ). EX$ may 27 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. be any combination of the following. "0" The F10 key will exit. "1" to "9" The F1 to F9 key will exit. "E" The ESC key will exit. EXAMPLE: EX$ = "E24" The ESC, F2, F4 and ENTER keys exit. RKEY% returns a numeric representation for the key which was pressed to cause the exit from PULLDOWN. On exit RKEY% may equal the following. 1 to 10 The F1 to F10 key caused the exit. 13 The ENTER key caused the exit. 27 The ESC key caused the exit. Arguments EX$ and RKEY% to may be used to simulate a selection from a pulldown window. To use the F1 key to simulate the first selection from the second pulldown window, argument EX$ must contain a "1" on entering PULLDOWN. Check to see if the F1 key caused the exit ( RKEY% = 1 ) from PULLDOWN. If it did set BAR% to 2 simulating the second pulldown window. Set WIND% to 1 to simulate the first selection from the second pulldown window. NOTE: IF ROUTINE CHNGPULL IS USED TO DISABLE A PULLDOWN WINDOW'S SELECTION AND THE SELECTION MAY ALSO BE SIMULATED BY AN EXIT KEY, ARGUMENT EX$ MUST BE ADJUSTED ACCORDINGLY TO PREVENT THE EXIT KEY FROM SIMULATING THE DISABLED SELECTION. ATTR% is the color. It follows the same rules as described in MAKEWIND except a flashing foreground is not permitted. Any value over 127 is changed to ATTR% MOD 128. KEYATTR% is the color of the key character for selections in the pulldown windows. If KEYATTR% = 0 the key character will be the same color as the other characters in each window selections. This would be appropriate if the first character in each selection is ALWAYS the key character. Setting KEYATTR% to a different color, or high intensity, allows users to distinguish the character as the key character for each item in the list. Any value for KEYATTR% over 127 is changed to KEYATTR% MOD 128. BRDR% is the pulldown window's border designation. BRDR% can equal 0, 1, 2, 10, 11 or 12 for pulldown windows. Any other value for BRDR% will 28 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. result in an error. SEE THE BORDER DESIGNATION CHART. 2.02 RSTRPULL ( RSTRMENUBAR% ) Description: Restores the display area under and deactivates the active pulldown window. The active pulldown window is the displayed pulldown window when routine PULLDOWN is exited. Normally a call to RSTRPULL will be made when PULLDOWN is exited. There may be times, however, when it is desirable to leave the active pulldown window and menubar displayed. If this is the case RSTRPULL should not be called after PULLDOWN is exited. If RSTRPULL is NOT called after PULLDOWN is exited the following will occur: 1. The pulldown window which was active when PULLDOWN was exited will remain displayed. 2. The pulldown window which was active when PULLDOWN was exited remains the active pulldown window. The next call to PULLDOWN will return to the active pulldown window with the previous ( active ) selection from the pulldown window covered by the scroll bar. NOTE: WHEN PULLDOWN IS RE-ENTERED UNDER THESE THE ROUTINE, PULLDOWN, EXPECTS THE ACTIVE PULLDOWN WINDOW AND MENUBAR TO BE INTACT. IF IT IS NOT, THE PULLDOWN WINDOW WILL NOT BE DISPLAYED AS EXPECTED. IT IS IMPORTANT THAT NO PORTION OF ACTIVE PULLDOWN WINDOW OR MENUBAR IS "PRINTED OVER" PRIOR TO RE-ENTERING PULLDOWN. Argument: RSTRMENUBAR% determines if the area under the menubar is restored to the display when RSTRPULL is called. If RSTRMENUBAR% = 0 the menubar will remain displayed after RSTRPULL is called and the menubar will remain active. Subsequent calls to PULLDOWN DO NOT save the area under the menubar. PULLDOWN expects the menubar to be intact. If RSTRMENUBAR% = 1 the area under the menubar is restored to the display and the menubar is deactivated. Subsequent calls to PULLDOWN save the area under, and display a new menubar. By virtue of a call to RSTRPULL the area under the active pulldown window is restored and the active pulldown window is deactivated. The status of argument RSTRMENUMAR% has no affect on the status of the active pulldown window. It only restores and deactivates the menubar or allows same to remain active. In either case the next call to PULLDOWN will position the scroll bar over the first selection of the menubar after a call to RSTRPULL. NOTE: THE SAVED DISPLAY AREA FOR THE ACTIVE PULLDOWN 29 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. WINDOW RESIDES IN WINDOW NUMBER 23. FUNCTION WAVAIL% CAN DETERMINE IF A PULLDOWN WINDOW IS ACTIVE. EXAMPLE: IF WVAIL%(23) = 0 ' A pulldown window is active. IF WVAIL%(23) = 1 ' A pulldown window is not ' active. THE SAVED DISPLAY AREA FOR THEN MENUBAR RESIDES IN WINDOW NUMBER 24. FUNCTION WVAIL% CAN DETERMINE IF THE MENUBAR IS ACTIVE. EXAMPLE: IF WAVAIL%(24) = 0 ' The menubar is active. IF WAVAIL%(24) = 1 ' the menubar is not active. 2.03 CHNGPULL ( BARITEM%, WINDITEM%, ATTR% ) NOTE: ROUTINE SETPULL MUST BE CALLED ONCE IN EVERY PROGRAM BEFORE ANY CALLS TO THIS ROUTINE. Description: Disables or enables the ability to select an selection or all selections, and changes the selection's color, in a pulldown window. Arguments: BARITEM% is the sequential number ( left to right ) of the menubar selection associated with the item's pulldown window. WINDITEM% is the row position of the item in the pulldown window's interior. If WINDITEM% = -1 all selections in the pulldown window are affected. NOTE: A LINE IN A PULLDOWN WINDOW OCCUPIES A ROW POSITION. ATTR% serves two purposes. If ATTR% > 0 it changes the color of the item specified by BARITEM% and WINDITEM% to ATTR% ( SEE THE COLOR ATTRIBUTE CHART ). The key character in the item also assumes the color specified by ATTR%. The ability to select the item from the pulldown window is disabled. Any value for ATTR% over 127 is changed to ATTR% MOD 128. If ATTR% = 0 the color of the item, and it's key char- acter is returned to it's original status as defined in the original call to PULLDOWN. The ability to select the item is enabled. 30 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ***** SCROLL WINDOWS ***** SCRLWIND places a scrollable list in the active window. A highlight ( scroll ) bar is placed over a specified item in the list and can be moved by the user via the UP and DOWN ARROW keys or MOUSE. Pressing the ENTER key or MOUSE on a selection returns the sequential item number covered by the scroll bar. The HOME, END, PG UP, and PG DN keys move the scroll bar as indicated. When a key is pressed SCRLWIND checks to see if the key matches the KEY CHARACTER of any selection in the list. If a match is found the scroll bar moves to that position in the list. Based on the number of buttons ( SEE ARGUMENT BUT% ), the minimum size of the window used for the scroll window varies as follows; # BUTTONS 0 1 2 (OK ) ( OK/CANCEL ) MIN. WINDOW WIDTH 5 11 18 MIN. ROWS WITH TITLEBOX 5 9 9 MIN. ROWS WITHOUT TITLEBOX 3 7 7 The size of the scrollable rows is reduced by four and the size of the scrollable width is reduced by six if buttons are used. The scrollable width must be consider if a STRING WON'T FIT error is encountered. 3.00 SCRLWIND (LIST$(), INFO$(), TL$, ENTRIES%, KIND$, RTRN%, LI%, FC% RKEY%, KEYATTR%, SCROLLBAR%, BUT%) NOTE1: THE ABOVE MUST BE ON ONE LINE IN THE QB/QBX/VBDOS ENVIRONMENT. NOTE2: FOR ADVANCED FEATURES SEE ROUTINE B4SCRL. THESE FEATURES INCLUDE THE ABILITY TO; 1. EXIT THIS ROUTINE USING DEFINABLE "EXIT KEYS". 2. SET MARKED ( TAGGED ) SELECTIONS ON ENTRY. 3. CHANGE THE COLOR OF THE "TAG" DESIGNATOR. 4. SUPPRESS REFRESHING OF THE SCROLL WINDOW ON ENTRY TO THIS ROUTINE. Description: Places a list ( LIST$() ) in the active window. The list is ENTRIES% long. There are two classes of scroll windows. 1. Non-virtual scroll windows. If argument KEYATTR% does not equal zero the scroll window is a non-virtual scroll window. On entry, SCRLWIND, verifies each element of LIST$() will fit in the scroll window with a 31 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. leading and trailing space added to the string. If any item will not fit an error is reported. Non-virtual scroll windows may be ( SEE ARGUMENT KIND$ ) regular, auto-exit, multiple mark, single mark, or list scroll windows. 2. Virtual scroll windows. If argument KEYATTR% equals zero, the scroll window is a virtual scroll window. Virtual scroll windows allow horizontal and vertical scrolling. The LEFT ARROW and RIGHT ARROW key become active. A differently colored "key character" is not permitted in a virtual scroll window as the character would not be visible when it is scrolled out if the window. No checks are made to verify the string length in a virtual scroll window. Virtual scroll windows may be ( SEE ARGUMENT KIND$ ) regular, auto-exit, multiple mark, single mark, or list scroll windows. If argument KEYATTR% equals zero and all elements of the list will fit in the window's width the scroll window assumes the properties of a non-virtual scroll window making the RIGHT ARROW and LEFT ARROW keys inactive. NOTE: ARGUMENT KEYATTR% DETERMINES IF A SCROLL WINDOW IS A VIRTUAL OR NON-VIRTUAL SCROLL WINDOW. SEE THE DESCRIPTION FOR KEYATTR% FOR MORE INFORMATION. Arguments: LIST$() is the array holding the strings to be placed in the scroll window. Each element of the array is a line in the scroll window. If the length of any element is greater then the width of the window - 4 and the scroll window is a non-virtual scroll window ( KEYATTR% <> 0 ) an error is reported. LIST$(1) must be the first string in the array, NOT LIST$(0). Each selectable item in LIST$() has a "KEY CHARACTER". The key character is the character which is searched for when a key is pressed while in the SCRLWIND environment. The key character defaults to the first character in each item. To designate the key character as a different character follow the character with a "@" in the string. EXAMPLE: LIST$(1) = "Get File" ( Key character = "G") LIST$(2) = "Save F@ile"( Key character = "F") The "@" will not be displayed when the string is printed in the scroll window. The description for KEYATTR% for this routine describes how to make the key character a different color, or high intensity, enabling users to distinguish it as the key character. 32 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. NOTE1: DO NOT PLACE THE "@" IN POSITION ONE OR TWO OF THE STRING AS IT WILL PRINT IN THE SCROLL WINDOW. AS STATED THE KEY CHARACTER WILL DEFAULT TO POSITION ONE IF THE "@" IS OMITTED FROM THE STRING. THIS ELIMINATES THE NEED TO PLACE THE "@" IN POSITION ONE OR TWO. NOTE2: IF ROUTINE B4SCRL IS USED TO SET A SCROLL WINDOW'S EXIT CRITERIA, AND ROUTINE B4SCRL'S ARGUMENT, EXIT$, CONTAINS AN "X" THE "KEY CHARACTER" SEARCH FEATURE IS DISABLED. DO NOT USE KEY CHARACTERS IF THIS IS THE CASE. ( SEE ROUTINE B4SCRL ) If an element of LIST$() = "-" and it is not the first item in the list or the last item in the list and all of the items in LIST$() will fit in the window's interior the scroll window will be segmented. A line will print across the window as determined by the position of the "-" in LIST$(). If the previous conditions are not met the string will print as a "-". EXAMPLE: LIST$(2) = "-" ( Provided LIST$(2) is not the last item in the list and the number of interior rows in the window is greater than two, LIST$(2) will print as a line.) INFO$() is an array holding the individual strings used for the information line for each entry in the scroll window ( SEE ROUTINE INFO-LINE ). As the scroll bar moves from entry to entry the message in the info-line changes based on the element of INFO$() which corresponds to the selected entry in the scroll window. If the scroll bar is over the third entry in the scroll window INFO$(3) will print in the info-line, provided the info-line is on. A SEGMENTING LINE IN THE SCROLL WINDOW MUST BE REPRESENTED BY AN ELEMENT IN INFO$(). IF A SEGMENTING LINE OCCUPIES THE FOURTH ROW OF THE SCROLL WINDOW INFO$(4) MUST EQUAL "". If the info-line is not going to be used or if a fixed info-line message is to be printed for all entries in the scroll window INFO$() must still be a dimensioned array prior to calling SCRLWIND. FOR NO INFO-LINE OR A FIXED INFO-LINE MESSAGE INFO$() MUST BE DIMENSIONED TO ZERO ( EX: DIM INFO$(0) ). TL$ is a string which will print in the title box of the scroll window. TL$ is ignored if the scroll window does not have a title box. TL$ is useful for virtual scroll windows. When a virtual scroll window scrolls up and down, TL$ does not move. When a virtual scroll window scrolls left and right TL$ scrolls with the window's interior. TL$ can, therefore, be longer than the window's width when used with a virtual scroll window. Although TL$ may be used in other ( non-virtual ) scroll 33 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. windows, the title for the scroll window can be generated in the call to MAKEWIND for the scroll window. ENTRIES% is the number of elements in the array ( LIST$() ) to use in the scroll window. KIND$ specifies the type of scroll window and may be any of the following. KIND$ DESCRIPTION ( Detail descriptions follow ) "A" "AN" Auto-exit scroll window. "M" "MN" Multiple mark ( tag ) scroll window. "S" Single mark ( tag ) scroll window. "L" List scroll window. No scroll bar. "V", "SV" View scroll window/ Single mark view. "N" Regular - scroll bar erased on exit. Any other value for KIND$ generates a regular scroll window. NOTE: AN "N" IN KIND$ ERASES THE SCROLL BAR ON EXIT. AUTO-EXIT SCROLL WINDOW ( KIND$ = "A" ) -- When in the scroll window environment if a key pressed matches the key character of an item in the scroll window the routine will be exited. The scroll bar moves to the item found. The position of the selected item in LIST$() will be returned in RTRN%. If RTRN% = 2, LIST$(2) was selected. SCRLWIND will exit with RKEY% equal to 13 simulating exit via the ENTER (RETURN) key. NOTE: IF ROUTINE B4SCRL IS USED TO SET A SCROLL WINDOW'S EXIT CRITERIA AND ROUTINE B4SCRL'S ARGUMENT EXIT$ CONTAINS AN "X" THE AUTO-EXIT FEATURE IS DISABLED. ( SEE ROUTINE B4SCRL ) MULTIPLE MARK SCROLL WINDOW ( KIND$ = "M" ) -- Pressing the <+> or INSERT key marks the item covered by the scroll bar. A right arrow to the left of the item in the scroll window signifies it has been marked. The color of this arrow may be changed by routine B4SCRL. Pressing the <-> or DELETE key un-marks an item if it was marked. Striking the PRINT ( not all systems ) key or SPACE BAR marks all items, unless they were all previously marked, in which case the PRINT ( not all systems ) key or SPACE BAR will un-mark all items. Pressing the ENTER or RETURN key returns a coded string in KIND$ which represents the marked items. If KIND$ ="" no items were marked. If any items were marked KIND$ will be ENTRIES% long. Each character in KIND$ will correspond to an element in LIST$(). If the first character of KIND$=" " LIST$(1) was not marked. If the second character, in KIND$ = CHR$(16), 34 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. LIST$(2) was marked. Each un-marked element of LIST$() will have a corresponding space (" ") in KIND$ while each marked element will have a corresponding right arrow ( CHR$(16) ) in KIND$. See the description for function MARKED% for a method of decoding KIND$. The multiple mark feature is disabled if a scroll window is also defined as a list scroll window or a single mark scroll window. NOTE: THE USE OF ROUTINE B4SCRL AFFECTS MULTIPLE MARK SCROLL WINDOWS AS FOLLOWS: 1. IF THE INSERT OR DELETE KEYS ARE SET AS EXIT KEYS BY ROUTINE B4SCRL THE INSERT AND DELETE KEYS WILL NO LONGER MARK AND UN-MARK ENTRIES. THE "+" AND "-" KEYS WILL STILL MARK AND UN-MARK ENTRIES. 2. IF B4SCRL'S ARGUMENT EXIT$ CONTAINS AN "X" THE SPACE BAR DOES NOT MARK/UN-MARK ALL ENTRIES. SINGLE MARK SCROLL WINDOW ( KIND$ = "S" ) --- Provided there is more than one item ( ENTRIES% > 1 ) in the scroll window, one item will be marked as in the preceding example for a "MULTIPLE MARK" scroll window. Only one item can be marked, however. The marked item follows the scroll bar. Pressing TAB, SHIFT TAB, ENTER, RETURN or ESC will exit the scroll window with the selected item in RTRN% and a representation of the "exit key" in RKEY%. If the scroll bar is over LIST$(2), RTRN% = 2 was selected. VIEW ONLY SCROLL WINDOW ( KIND$ = "V" OR "SV" ) --- The window will be filled with the strings in LIST$() and the routine will be exited. IF KIND$ = "SV" the scroll window is "VIEW ONLY -SINGLE MARK" scroll window. If ENTRIES% > 1 the item designated by the value of RTRN% will be marked. ( See description for RTRN%. ) LIST SCROLL WINDOW ( KIND$ = "L" ) --- This generates a list scroll window. There is no scroll bar. This may be useful for viewing virtual scroll windows. It may be used for regular scroll windows also. Any other value for KIND$ when entering SCRLWIND results in a "REGULAR" scroll window. After the scroll bar is moved to the selected item, pressing the ENTER or RETURN key returns the selected item in RTRN%. Routine B4SCRL provides alternate means to exit SCRLWIND. RTRN% serves two purposes. One is to place the scroll bar over the item specified by RTRN% when entering SCRLWIND. If RTRN% < 1 or RTRN% > ENTRIES%, 35 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. RTRN% defaults to 1 and the scroll bar will be positioned over the first item in the window. EXAMPLE: RTRN% = 2 -- If there are a minimum of two items in the scroll window ( ENTRIES% > 1 ) the scroll bar will be over LIST$(2) when entering SCRLWIND. RTRN% also returns the selected item when exiting SCRLWIND. If RTRN% = 2, LIST$(2) was selected when SCRLWIND was exited. If routine B4SCRL is used prior to calling SCRLWIND it is possible to exit SCRLWIND on any attempt to scroll before the first entry in the scroll window or past the last entry in the scroll window. This feature affects the value of RTRN% ( SEE ROUTINE B4SCRL). NOTE: THE ITEM SELECTED IN LIST$(), AS INDICTED BY THE VALUE OF RTRN%, MAY CONTAIN A "@" TO INDICATE THE KEY CHARACTER. IF IT IS NECESSARY TO PRINT THE ITEM THE "@" CAN BE REMOVED FROM IT USING THE FOLLOWING FUNCTION. ' FUNCTIONS MUST BE DECLARED. RTRN% = ITEM # SELECTED ' FROM LIST$(). DECLARE FUNCTION NO$( ITEM$ ) '( Place this at the start of the module.) ' IF RTRN% = 2 AND LIST$(RTRN%) = "Save F@ile", LIST$(2) ' CAN BE PRINTED AS "Save File" as follows. PRINT NO$( LIST$(RTRN%) ) ---------------------------------------------------------- ' INCLUDE THIS FUNCTION IN YOUR PROGRAM FUNCTION NO$ ( ITEM$ ) A% = INSTR ( ITEM$, "@" ) IF A% < 3 THEN ' "@" SHOULD NOT BE IN POSITION NO$ = ITEM$ ' 1 OR 2, OR NO "@" IS IN ITEM$. ELSE NO$ = LEFT$(ITEM$, A% - 1) + MID$(ITEM$, A% + 1) END IF END FUNCTION ---------------------------------------------------------- LI%, on entry to routine SCRLWIND, specifies which row ( of the interior of the scroll window ) to place the scroll bar on. It is used, on entry, with argument RTRN% to place the scroll bar over a specific entry on a specific row. This is useful if it is necessary to exit a scroll window and re-enter it with the scroll bar over the same entry and on the same line as on the previous exit. Set this argument to one if it is not required . The following restrictions apply. 36 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 1. If LI% is less than one or LI% is greater than the number of entries ( ENTRIES% ) LI% is indeterminate. The scroll bar will be positioned over the entry specified by argument RTRN%. 2. Argument RTRN% determines the line the scroll bar will occupy ( argument LI% is ignored ) if an attempt is made to place an entry on a line greater than the subscript of the entry. For example, LIST$(2) can not be placed on line 3 of the scroll window. This would cause line one to be blank. If RTRN% = 2 on entry, LI% defaults to 2 also, if LI% is set to a number higher than 2. 3. If all of the entries fit in the scroll window argument LI% is ignored on entry. The scroll bar will occupy the line based on the value of RTRN%. If RTRN% = 3 the scroll bar will be positioned on line 3 regardless of the value of LI% 4. If there are more entries than interior rows in the scroll window, the last "interior rows" of entries fill in from the bottom of the scroll window. For example, assuming a scroll window has 10 interior rows and 20 entries, the 20th entry can be positioned no higher than the 10th interior row, the 19th entry can be positioned no higher than the ninth interior row, and so on. If one of the last "interior rows" of entries is specified by argument RTRN% on entry, and LI% attempts to place the entry on row higher than outlined above, LI% is adjusted appropriately. On exit from routine SCRLWIND, LI% equals the interior row number of the scroll window that the scroll bar occupied prior to the exit. FC% is used with virtual scroll windows to position a specified string position for the entries in the scroll window on the first useable column (2) of the scroll window. On entry to SCRLWIND, FC% sets the string position for the first column of the scroll window. On exit FC% points to the string position occupying column two. FC% IS ONLY APPLICABLE TO VIRTUAL SCROLL WINDOWS. FC% has one purpose. It allows re-entry into a virtual scroll window exactly as it was displayed on exit if used with arguments RTRN% and LI% on re-entry. Set this argument to one if it is not required. EXAMPLE: On entry FC% = 5 and LIST$(1) ="12345678901234". "5678901234" will be displayed in a virtual scroll window. The first displayed character in LIST$(1) will be "5". 37 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. RKEY% represents the key or action used to exit SCRLWIND. RKEY% may equal any of the following. RKEY% EXIT KEY/ACTION KIND$ ** 1 to 10 F1 to F10 ALL ** 11 PAGE UP ALL ( *EXTENDABLE ) ** 12 PAGE DOWN ALL ( *EXTENDABLE ) 13 ENTER ( RETURN ) or ALL 13 AUTO-EXIT FEATURE. ** 13 MOUSE SELECTION ( Single or double click ) ALL < OK > SELECTED ALL ( > 0 BUTTONS ) ** 14 SHIFT TAB ALL ** 14 LEFT ARROW ALL ( NON-VIRTUAL ) ** 15 TAB ALL ** 15 RIGHT ARROW ALL ( NON-VIRTUAL ) ** 16 UP ARROW/MOUSE ALL (**EXTENDABLE ) ** 19 DOWN ARROW/MOUSE ALL (**EXTENDABLE ) 27 ESC ALL < CANCEL > SELECTED ALL ( 2 BUTTONS ) ** 30 HOME ALL (**EXTENDABLE ) ** 35 END ALL (**EXTENDABLE ) ** 40 INSERT ALL ** 45 DELETE ALL ** 50 MARK an entry "M" (**EXTENDABLE ) ** 55 UN-MARK an entry "M" (**EXTENDABLE ) ** 200 Mouse pressed outside ALL ( NO BUTTONS ) of scroll window. ** Requires calling routine B4SCRL prior to calling routine SCRLWIND. ( SEE ROUTINE B4SCRL ). KEYATTR% is the color of the key character for each item in the scroll window. If KEYATTR% = 0 the key character will be the same color as the other characters for each window item. This would be appropriate if the first character in each item is ALWAYS the key character. KEYATTR% MUST EQUAL ZERO FOR A SCROLL WINDOW TO BE A VIRTUAL SCROLL WINDOW. IF KEYATTR% = 0 THE 38 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. SCROLL WINDOW IS TREATED AS A VIRTUAL SCROLL WINDOW. CHECKS TO DETERMINE IF THE ELEMENTS OF LIST$() ARE TOO LONG TO FIT IN THE WINDOW ARE NOT MADE. Setting KEYATTR% to a different color, or high intensity, allows users to distinguish the character as the key character for each item in the list. KEYATTR% has no effect on the background color of an item when it is covered by the scroll bar. It can effect the background color for the key character. This is useful for computers without high intensity or color capabilities. IF KEYATTR% <> 0 AND ANY SELECTION IN THE LIST WILL NOT FIT IN THE SCROLL WINDOW ALLOWING A LEADING AND TRAILING SPACE AN ERROR WILL BE REPORTED. SCROLL WINDOWS WITH BUTTONS ARE, IN EFFECT, REDUCED IN WIDTH BY SIX SPACES. THEREFORE, IF KEYATTR% <> 0 THE SCROLL WINDOW MAY NOT BE A VIRTUAL SCROLL WINDOW. SCROLLBAR% determines if scroll bars on the right and bottom border are displayed. Pressing the mouse on a scroll bar arrow simulates pressing the corresponding arrow key. If SCROLLBAR% > 0 the scroll bars will be displayed with the following exceptions. 1. If the scroll window has less than 3 interior rows the vertical scroll bar is not displayed. The scroll arrows will, however, be displayed on scroll windows with two interior rows. 2. If the scroll window is made an "EXTENDABLE" scroll window by a previous call to routine B4SCRL the vertical bar is not appropriate and not displayed. 3. If the scroll window is NOT a virtual scroll window the horizontal scroll bar is not necessary and is not displayed. BUT% allows < OK > and < CANCEL > buttons for the scroll window. Buttons are selected by moving the cursor to the button using the tab or shift tab keys. If ENTER or the SPACE BAR is pressed and the cursor is on a button , the button is selected. If the mouse is released with the mouse cursor over a button, the button is selected. If BUT% = 1 the < OK > button is displayed. If BUT% = 2 the < OK > and < CANCEL > buttons are displayed. Selecting the < OK > button simulates pressing the ENTER key on a selection (RKEY% = 13). Selecting the < CANCEL > button simulates pressing ESC (RKEY% = 27). IF BUT% = 1 the ESC key will not exit unless an "E" is included in routine B4SCRL's argument EXIT$. Using buttons reduces the interior rows of the scroll window by four and the interior width of the scroll window by six. This is required to "make room" for the buttons. 39 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. NOTE: ALTHOUGH BUTTONS ARE ALLOWED WITH "EXTENDABLE" ( SEE ROUTINE B4SCRL ) SCROLL WINDOWS, PERFORMANCE ( ESPECIALLY IN 286 OR SLOWER PROCESSORS) IS SACRIFICED. IT IS SUGGESTED EXTENDABLE SCROLL WINDOWS ARE USED WITHOUT BUTTONS. IF BUTTONS ARE REQUIRED SPEED CAN BE ENHANCED BY USING FUNCTION CHOICEBAR, FOR THE BUTTONS, WITH ROUTINE SCRLWIND, TO OBTAIN THE BUTTON EFFECT. THIS WILL REQUIRE USING A "T" IN ROUTINE B4SCRL'S ARGUMENT EXIT$ TO ALLOW THE TAB AND SHIFT/TAB KEYS TO EXIT FROM THE SCROLL WINDOW AND ENTER FUNCTION CHOICBAR. IT WILL ALSO REQUIRE AN "O" IN ROUTINE B4SCRL'S ARGUMENT EXIT$. THIS WILL EXIT ROUTINE SCRLWIND IF THE MOUSE IS PRESSED OUTSIDE OF SAME. A CHECK CAN BE MADE WHEN THE MOUSE IS PRESSED OUTSIDE OF THE SCROLL WINDOW TO DETERMINE IF IT IS PRESSED ON A CHOICEBAR BUTTON.

The entries in the scroll window and the text for the info-line are the items in the data statements, as they are read into LIST$() and INFO$(). The fourth parameter in the call to SCRLWIND is the number of items in the list ( 11 ). As KIND$ ="A" before calling SCRLWIND, the scroll window is an "AUTO-EXIT SCROLL" window. Since RTRN% = 3 when entering SCRLWIND the scroll bar will start over the third item ( THREE ). The sixth DATA item for LIST$() loads LIST$(6) with "-". Therefore, a line will print in row six of the scroll window. The key character for each item will be red (KEYATTR% = 116 ). RTRN% will equal the selected item, and RKEY% will represent the exit key when SCRLWIND is exited. As reading the data takes time, quicker scroll windows will be generated if all arrays used in scroll windows are filled using READ and DATA statement during program initialization. 3.01 B4SCRL ( EXIT$, MARK$, TAGCOL%, NOREFRESH% ) Description: Sets the "exit keys" or "exit circumstances", the marked ( tagged ) selections on entry, and marked selection arrow color for subsequent call to SCRLWIND. May also be used to suppress the "refreshing" of a scroll window on entry. NOTE1: IT IS NOT NECESSARY TO CALL B4SCRL PRIOR TO CALLING SCRLWIND UNLESS ONE OF B4SCRL'S FEATURES ARE REQUIRED. NOTE2: B4SCRL ONLY AFFECTS THE NEXT CALL TO SCRLWIND FOR ALL ARGUMENTS. THEREFORE, IF B4SCRL IS REQUIRED FOR A PARTICULAR SCROLL WINDOW IT MUST ALWAYS BE CALLED PRIOR TO CALLING SCRLWIND FOR THAT SCROLL WINDOW. ALWAYS PLACE A CALL TO B4SCRL, IF IT IS REQUIRED, IMMEDIATELY BEFORE THE CALL TO SCRLWIND. 41 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. EXAMPLE: CALL B4SCRL (...... ' IF B4SCRL IS REQUIRED CALL SCRLWIND (..... ' IT MUST PRECEDE SCRLWIND. CALL SCRLWIND (.......' THE PREVIOUS CALL TO ' B4SCRL DOES NOT AFFECT ' THIS CALL TO SCRLWIND. Arguments: EXIT$ sets the exit keys or exit circumstances for a subsequent call to SCRLWIND. Normally SCRLWIND exits via the ESC or ENTER keys. There is no need to use B4SCRL to provide alternate means to exit unless the scroll window requires same. EXIT$ may be any combination of the following. "E" The ESC key will exit SCRLWIND. "R" The ENTER (RETURN) key will exit SCRLWIND. "0" The F10 key will exit SCRLWIND. "1" to "9" The F1 to F9 keys will exit SCRLWIND. "I" The INSERT key will exit SCRLWIND. "D" The DELETE key will exit SCRLWIND. "T" TAB and SHIFT/TAB keys will exit SCRLWIND provided the scroll window has no buttons. "A" RIGHT ARROW and LEFT ARROW keys will exit SCRLWIND. SCRLWIND must be NON-VIRTUAL. "M" The mouse will exit SCRLWIND if it is RELEASED with the cursor on a valid selection. ( Single click ) "MC" Double clicking the mouse on a selection will exit. "O" The mouse will exit SCRLWIND if it is pressed outside of the scroll window AND the scroll window has no buttons. "X" This makes the scroll window an "EXTENDABLE" scroll window. Any attempt to scroll past the last entry ( PAGE DOWN, DOWN ARROW OR MOUSE ) in the scroll window or scroll before the first entry ( PAGE UP, UP ARROW OR MOUSE ) in the scroll window will exit SCRLWIND. The HOME or END keys exit SCRLWIND. If the scroll window is a multiple mark scroll window ( argument KIND$ for routine SCRLWIND equals "M" ) any change in mark status of an entry will exit SCRLWIND. ( FURTHER EXPLANATION AND RESTRICTIONS FOLLOW. ) 42 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. EXAMPLE: EXIT$ = "12DR" The F1, F2, DELETE, and ENTER keys exit routine SCRLWIND. NOTE1: IF EXIT$ CONTAINS AN "X" THE SCROLL WINDOW IS AN "EXTENDABLE" SCROLL WINDOW. ALL ENTRIES MUST FIT IN THE SCROLL WINDOW OR AN ERROR WILL BE REPORTED. IF THERE ARE 10 INTERIOR ROWS IN THE SCROLL WINDOW THE NUMBER OF ENTRIES ( ARGUMENT ENTRIES% FOR ROUTINE SCRLWIND ) MUST BE EQUAL TO, OR LESS THAN, 10. NOTE2: IF THE INSERT OR DELETE KEYS ARE USED AS EXIT KEYS AND THE SCROLL WINDOW IS A MULTIPLE MARK, EXTENDABLE, SCROLL WINDOW THE INSERT AND DELETE KEYS WILL NO LONGER MARK AND UN-MARK ENTRIES. THE "+" AND "-" KEYS WILL STILL MARK AND UN-MARK ENTRIES, HOWEVER. Placing an "X" in EXIT$ makes the scroll window an "EXTENDABLE" scroll window. This provides the ability to scroll through records in large random access, binary, ISAM, BTRIEVE, or many other data files. On entry to SCRLWIND memory constraints may prohibit placing all records in a database in a scroll window. With "EXTENDABLE" scroll windows, the first 15 records of a data file may be placed in a scroll window with 15 interior rows. NOTE: THE NUMBER OF INTERIOR ROWS IN A SCROLL WINDOW IS EQUAL TO THE NUMBER OF ROWS IN THE WINDOW ( AS SET BY THE CALL TO MAKEWIND FOR THE SCROLL WINDOW ) MINUS 2 IF THE CALL TO MAKEWIND DID NOT SPECIFY A TITLE BOX. IF THE CALL TO MAKEWIND SPECIFIED A TITLE BOX THE NUMBER OF INTERIOR ROWS EQUALS THE ROWS SET BY THE CALL TO MAKEWIND MINUS 4. IF BUTTONS ARE USED THE NUMBER OF INTERIOR ROWS IS REDUCED BY AN ADDITIONAL 4 ROWS. USING BUTTONS IN "EXTENDABLE" SCROLL WINDOWS IS NOT RECOMMENDED AS A NOTICEABLE ( ESP- ECIALLY ON 286 OR SLOWER MICROPROCESSORS ) DEGRADATION WILL BE OBVIOUS. An attempt to scroll past the 15th record in the scroll window or before the first record in the scroll window causes SCRLWIND to be exited. Argument RKEY% ( from routine SCRLWIND ) can be used to determine the key or circumstance which caused the exit. The following lists the values returned by SCRLWIND's argument RKEY% which are unique to "EXTENDABLE" scroll windows. - RKEY% = 19 -- The DOWN ARROW was pressed or the MOUSE was pressed on the windows bottom border ( SEE FOLLOWING NOTE ) with the scroll bar on the last entry in the scroll window. An attempt is being made to access the next record ( relative to the last record in the scroll window ) in the data file. On exit, a check should be 43 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. made to determine if the last record in the scroll window is not the last record in the data file. If it is not, all records in SCRLWIND's arguments LIST$() should be shifted to the preceding element of LIST$(). The last element of LIST$() should be filled with the next record.

NOTE: RKEY% MAY ALSO EQUAL 19 IF THE SCROLL WINDOW IS A MULTIPLE MARK, EXTENDABLE, SCROLL WINDOW AND A MARK KEY ( INS, DEL, +, or - ) IS PRESSED WITH THE SCROLL BAR ON THE LAST ENTRY. IF THE ENTRY DOES NOT CHANGE "MARK" STATUS RKEY% WILL EQUAL 19 EMULATING THE DOWN ARROW KEY. IF THE ENTRY CHANGES "MARK" STATUS RKEY% WILL EQUAL 50 OR 55.

They remain available as a means to exit an "EXTENDABLE" scroll window, however. SEE ARGUMENT RKEY% FOR ROUTINE SCRLWIND. NOTE: WHEN A SCROLL WINDOW IS AN EXTENDABLE SCROLL WINDOW IT'S OPTIONS ARE AFFECTED AS FOLLOWS: 1. PRESSING THE FIRST LETTER OF AN ENTRY OR "KEY CHARACTER" OF AN ENTRY DOES NOT MOVE THE SCROLL BAR TO THE ENTRY. AS THE SEARCH IS CONFINED TO THE ENTRIES IN THE SCROLL WINDOW, AND ALL OF THE RECORDS ARE NOT IN THE SCROLL WINDOW, "KEY CHARACTERS", ARE USELESS. 2. AUTO-EXIT SCROLL WINDOWS ARE NOT PERMITTED ALSO, FOR THE SAME REASON. TO SEARCH FOR A RECORD, THE F1 KEY, FOR EXAMPLE, CAN BE USED TO EXIT SCRLWIND AND PROMPT THE USER FOR A SEARCH CRITERIA. THE DATABASE CAN BE SEARCHED, AND IF A MATCH IS FOUND, SCRLWIND MAY BE RE- ENTERED DISPLAYING THE "FOUND" RECORD. 3. THE OPTIONAL SCROLLBAR ON THE RIGHT BORDER OF THE SCROLL WINDOW IS DISABLED FOR THE CALL TO SCRLWIND. 4. THE SPACE BAR ( PRINT KEY ON SOME SYSTEMS ) DOES NOT MARK/UN-UNMARK ALL ENTRIES IN MULTIPLE MARK SCROLL WINDOWS. MARK$ is a string representing those entries, on entering SCRLWIND, to be marked. This is only appropriate if the scroll window is a multiple mark scroll window ( SCRLWIND's argument KIND$ = "M" ). MARK$ must be the exact length as the number of entries in the scroll window. IF IT IS NOT IT IS IGNORED! On entry to routine SCRLWIND a space ( CHR$(32) ) in MARK$ is decoded as an un-marked entry. If the first character of MARK$ = " " the first entry in the scroll window will not be marked. An arrow ( CHR$(16) ) in MARK$ is decoded as a marked entry. If the second character of MARK$ = CHR$(16) the second entry in the scroll window is marked. Each character in MARK$ represents a marked or un-marked entry in the scroll window. On exit from routine SCRLWIND, SCRLWIND's argument KIND$ holds the string representation for those marked and un-marked items. B4SCRL's argument MARK$ holds the string representation on entry only. If the scroll window is to be re-entered it is necessary to refresh MARK$. The following example demonstrates this. REENTER: KIND$ = "M" ' MAKE A MULTIPLE MARK SCROLL WINDOW CALL B4SCRL ("", MARK$ ) ' ENTER WITH SOME ENTRIES ' MARKED. 49 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ' WHILE IN THE SCROLL WINDOW ENVIRONMENT THE MARKED ' ENTRIES MAY CHANGE. CALL SCRLWIND ( L$(), I$(), TL$, ENTRIES%, KIND$ ........ ' KIND$ REPRESENTS THE MARKED ENTRIES ON EXIT MARK$ = KIND$ ' MARK$ MUST BE REFRESHED IF THE SCROLL ' WINDOW IS TO BE RE-ENTERED ' KIND$ = "" IF NOTHING WAS MARKED. IF LENGTH OF MARK$ IS ' NOT ENTRIES% LONG IT IS IGNORED, THEREFORE ON RE-ENTRY ' NO ENTRIES ARE MARKED. GOTO REENTER NOTE: IT IS THE PROGRAMMER'S RESPONSIBILITY TO ASSURE MARK$ CONTAINS SPACES ( " " ) AND ARROWS ( CHR$(16) ) ONLY. ANY OTHER CHARACTERS WILL MARK ENTRIES WITH THAT CHARACTER ON ENTRY ONLY. IF THE ENTRY IS UN-MARKED AND RE-MARKED IN THE SCROLL WINDOW ENVIRONMENT THE NORMAL MARK CHARACTER IS USED. TAGCOL% sets the color of the marked "tagged" selection arrow for mark scroll windows. If TAGCOL% = 0 the arrow assumes the same color as the text in the scroll window. TAGCOL% is adjusted to TAGCOL% AND 15 if it is set over 15. It only affects the arrow's foreground color. NOREFRESH% can be used to re-enter a scroll window without re-printing the text in same. It is used to enhance the speed on re-entry and avoid any flicker by needlessly re-printing the text. If NOREFRESH% = 0 ( the default without calling B4SCRL ) the scroll window is refreshed on entry. If NOREFRESH% = 1 the scroll window is not refreshed on entry. MOTE: SETTING NOREFRESH% TO ONE IS ONLY APPROPRIATE IF: 1. The scroll window is already displayed. 2. The scroll window is being re-entered in the same state as it was exited. 3.02 MARKED% (KIND$, START%) Description: MARKED%(KIND$, START%) is a function used to decode SCRLWIND's argument KIND$ after a multiple mark scroll window is exited. MARKED%(KIND$, START%) will equal the next position in KIND$ starting from position START% which contains a CHR$(16). If the third element (item) in LIST$() was marked in the call to SCRLWIND and START% =1, THEN: MARKED%(KIND$,START%) = 3. 50 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Arguments: KIND$ is the string returned by calling SCRLWIND with the MARKED option ON. KIND$ = "" if no items were marked. START% is the position in KIND$ to start searching for a CHR$(16). A CHR$(16) in KIND$ represents a marked element in the string array LIST$() used in SCRLWIND. Every time a position in KIND$ is found which corresponds to a marked element of LIST$(), START% is set to a new value which is equal to the "marked" position in KIND$ + 1. This is the next position in KIND$ where the search will start for another "marked" position. If MARKED% =0 there are no more "marked" positions in KIND$ or KIND$ = "". ------------------------------------------------------- 'EXAMPLE USING THE FUNCTION MARKED% (KIND$,START%) THIS 'EXAMPLE PRINTS THE MARKED ITEMS IN LIST$() AFTER A CALL 'TO SCRLWIND.

START% is auto- matically set to 5, the next position to start searching KIND$ for a "marked" position in KIND$. The second loop will set MARKED% (KIND$,START%) to 10 and LIST$(10) will print. As there are no more marked positions, MARKED% = 0 and the loop be exited. 51 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ****** INPUT ROUTINES ****** Input routines provide the ability to generate a single character input field ( GETANS ), a single input field ( INPTWIND ), or multiple input fields ( MULTINPT ). Full editing is provided within each field. Up to 10 multiple input screens may be used, with each screen capable of supporting up to 150 fields. Fields may be defined as numeric, alpha/numeric, or date. Numeric fields may be designated 0 to 6 decimal places and optionally padded with leading zeros. Numerous additional options are available. Two additional input routines provide input in the form of displayed choices. Function CHOICEBAR% provides up to 10 choices displayed on a "choicebar". Function CHOICEWIND% generates a text filled window with a choicebar in same. 4.00 INPTINIT ( DATEFORMAT%, ISDOT%, AT1%, BLANK%, SND% ) See: Example - Input window Description: Initialization routine for input routines INPTWIND, MULTINPT, CHOICEWIND%, and CHOICEBAR%. Function CHOICEBAR% is used by routine SCRLWIND for the < OK > and < CANCEL > buttons. INPTINIT MUST BE CALLED ONCE IN EVERY PROGRAM BEFORE ANY CALLS TO THESE ROUTINES (INCLUDING SCRLWIND WITH BUTTONS). NOTE: IF A CLEAR STATEMENT IS EXECUTED BY THE PROGRAM INPUT INITIALIZATION MEMORY IS LOST. INPTINIT MUST BE CALLED AFTER A CLEAR STATEMENT TO RE-INITIALIZE INPUT INITIALIZATION MEMORY. Arguments: DATEFORMAT% sets the valid date format for input routines INPTWIND and MULTINPT. If a field in either input routine is designated a date field, the field can not be exited if the entered date does not match the date format as specified by DATEFORMAT%. The valid date format varies predicated on the specified field width for the date field. If set outside it's allowable range, DATEFORMAT% defaults to 1. Listed are valid values for DATEFORMAT% and the corresponding valid date formats. DATEFORMAT% DATE FORMAT DATE FORMAT (FIELD WIDTH = 10) (FIELD WIDTH = 8) 1 MM-DD-YYYY MM-DD-YY 2 MM/DD/YYYY MM/DD/YY 3 DD-MM-YYYY DD-MM-YY 4 DD/MM/YYYY DD/MM/YY 5 DD.MM.YYYY DD.MM.YY 52 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ISDOT% sets a period or comma for the decimal designator. If ISDOT% = 1 the decimal designator is a period. If ISDOT% = 0 the decimal designator is a comma. This is appropriate for some users outside of the USA. AT1% determines if the cursor will enter input fields used in routines INPTWIND and MULTINPT on the first character of text in the field or after the last character of text in the field. If AT1% = 1 the cursor will enter a field on the first character of text in the field. If AT1% = 0 the cursor will enter fields at the position after the last character of text in the field. NOTE: NON-INPUT FIELDS DEFINED IN CALLS TO ROUTINE MAKEFIELD FOR ROUTINE MULTINPT MAY HAVE THE CURSOR SET TO ANY POSITION IN THE FIELD VIA THE CALL TO MAKEFIELD FOR AN INDIVIDUAL FIELD. BLANK% allows text in input fields used in routines INPTWIND and MULTINPT to be erased when the FIRST valid key is pressed. If BLANK% = 1 the text in a field will be erased when a valid key is pressed and the character represented by the key will be the first text character in the field. If BLANK% = 0 the character represented by a valid key, when it is pressed, will be added to any text previously in the field. The FIRST valid key pressed will not erase the field's text. NOTE: MANY FIELDS USED BY ROUTINE MULTINPT ARE NON-INPUT FIELDS. THE VALUE OF BLANK% DOES NOT AFFECT THESE FIELDS. SND% allows the default sound, as set by routine SETWIND, to be generated when and invalid key is pressed in routines INPTWIND and MULTINPT. If SND% = 1 pressing an invalid character will make the default sound. If SND% = 0 pressing an invalid character makes no sound. 4.01 B4INPT (INPUTEXIT$, RESTRICT$) Description: Sets "exit keys" and the field restrict string for a subsequent call to INPTWIND. NOTE1: CALLING ROUTINE B4INPT BEFORE A CALL TO ROUTINE INPTWIND IS NOT REQUIRED UNLESS ONE OF B4INPT'S SPECIAL FEATURES ARE REQUIRED. NOTE2: A CALL TO B4INPT ONLY AFFECTS THE NEXT CALL TO INPTWIND. CALLS TO B4INPT SHOULD BE PLACED DIRECTLY BEFORE CALLS TO INPTWIND. 53 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. EXAMPLE: CALL B4INPT (....... CALL INPTWIND (..... ' this is affected by ' the call to B4INPT. CALL INPTWIND (..... ' this is not affected ' by the call to B4INPT. Arguments: INPUTEXIT$ sets the keys which will exit input routine INPTWIND. INPUTEXIT$ does not affect input routine MULTINPT. Routine SETINPT is used to set exit keys for individual MULTINPT screens. If INPUTEXIT$ = "" the default keys will exit INPTWIND. The default exit keys are dependent on the number of buttons used by INPTWIND. DEFAULT EXIT KEYS NO BUTTONS -------------------- ENTER and ESC ONE BUTTON < OK > ------------- ENTER TWO BUTTONS < OK >< CANCEL > -- ENTER AND ESC ENTER exits INPTWIND returning the edited text. ENTER always exits all input windows, even if INPUTEXIT$ defines new exit keys. ESC always exits two button input windows. If INPUTEXIT$ defines new exit keys for input windows without buttons, ESC will not exit unless an "E" is included in INPUTEXIT$. If ESC is not an exit key the field's text is returned to it's pre-edited state and INPTWIND is not exited if ESC is pressed. If ESC is an exit key, and it is pressed, INPTWIND is exited returning the EDITED text. Using INPUTEXIT$ allows additional or different keys to exit INPTWIND. INPUTEXIT$ may consist of any combination of the following characters. Character "Exit" key. "0" F10 "1","2","3","4","5","6","7","8","9" F1 to F9 "E" ESC "U" PGUP "D" PGDN "VIEW" -- This causes the input window to be displayed and exited. The input window remains active. NOTE: THE FOLLOWING APPLY FOR NO BUTTON INPUT WINDOWS. "O" - The mouse is pressed outside of the input window. "T" - The TAB or SHIFT/TAB keys exit. NOTE: THE MOUSE "BELONGS" TO ROUTINE INPTWIND IF IT HAS BUTTONS. INPTWIND CAN NOT BE EXITED IF THE LEFT MOUSE BUTTON IS PRESSED OUTSIDE OF THE FIELD. TO USE INPUT FIELDS AND DETECT THE IF THE LEFT MOUSE BUTTON IS PRESSED OUTSIDE OF A FIELD ROUTINE "NO BUTTON INPUT WINDOWS" OR MULTINPT MUST BE USED. 54 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Example: If INPUTEXIT$ = "02E" the F10, F2, ESC, and RETURN (ENTER) keys will exit INPTWIND. see the description for routine INPTWIND ( argument RKEY% ). The following eliminates ENTER as exit key. DO CALL B4INPT ("12","") ' F1 / F2 = exit keys CALL INPTWIND (........ RKEY% ' SEE ROUTINE INPTWIND LOOP WHILE RKEY% = 13 ' RKEY% = 13 for ENTER CALL RSTRINPT (1) ' SEE ROUTINE RSTRINPT NOTE: IF THE ESC KEY IS NOT AN EXIT KEY AND INPUTEXIT$ DOES NOT EQUAL "" THE ESC KEY WILL RETURN THE TEXT IN THE INPUT FIELD TO IT'S PRE-EDITED STATE. INPTWIND WILL NOT BE EXITED. IF THE ESC KEY IS AN EXIT KEY INPTWIND IS EXITED RETURNING THE EDITED TEXT, WHEN ESC IS PRESSED. RESTRICT$ is the field's restrict string. It holds the allowable characters which can be entered in the input field for a subsequent call to INPTWIND. RESTRICT$ IS IGNORED IF THE FIELD IS NOT AN ALPHA/NUMERIC FIELD. Only use RESTRICT$ if necessary. For example if RESTRICT$ = "1234567890()-" only the characters included in a phone number can be entered in the field. If RESTRICT$ = "" for an alpha/numeric field all valid alpha/numeric characters may be entered in the field. 4.02 INPTWIND ( P$, CODE$, TR%, LC%, WD%, WATTR%, FATTR%, RTRN$, RKEY%, BUT%, BRDR%) See: Example - Input window NOTE1: PLACE THE ABOVE CALL TO INPTWIND ON ONE LINE IN THE QB/QBX ENVIRONMENT. NOTE2: ROUTINES INPTINIT AND SETWIND MUST BE CALLED AT LEAST ONCE IN ANY PROGRAM PRIOR TO CALLING THIS ROUTINE. NOTE3: WHEN AN INPUT WINDOW ( OR LINE ) IS MADE IT BECOMES THE ACTIVE INPUT WINDOW UNTIL IT IS DEACTIVATED BY A CALL TO ROUTINE RSTRINPT. ON ENTRY THIS ROUTINE WILL MAKE A NEW INPUT WINDOW IF THERE IS NO ACTIVE INPUT WINDOW. IF THERE IS AN ACTIVE INPUT WINDOW THIS ROUTINE SIMPLY RE- ENTERS IT. A NEW INPUT WINDOW IS NOT MADE. AN UNDERSTANDING OF ROUTINE RSTRINPT IS NECESSARY TO FULLY UNDERSTAND THIS ROUTINE. Description: On entry this routine will do one of the following. 1. IF THERE IS NO ACTIVE INPUT WINDOW this routine makes 55 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. an input field, which may optionally be windowed. The area under the field or window is automatically saved. The input window becomes the active input window. The area under the window ( or line ) can be restored after exiting INPTWIND by calling routine RSTRINPT. RSTRINPT also deactivates the active input window. 2. IF THERE IS AN ACTIVE INPUT WINDOW calling INPTWIND re- enters it. Arguments for top row (TR%), left column (LC%), field width (WD%) and color (ATTR%) are ignored. A new input window is NOT made. The active input window ( from a previous call to INPTWIND ) is used and MUST be intact. The following outlines the suggested use for routines INPTWIND and RSTRINPT. A. Call INPTWIND. Enter data and exit. B. Check the data. C. If the data is good proceed to step D. If the data is not good go back to step A. As RSTRINPT has not been called the input window is still active. A new input window will not be made. The existing active input window is simply re-entered. D. Call RSTRINPT. The active input window made in step A is deactivated by RSTRINPT. The display area covered by the input window may optionally be restored. The next call to INPTWIND will make a new input window as an active input window will not exist. IF AN ACTIVE INPUT WINDOW UNKNOWINGLY EXISTS ON ENTRY TO INPTWIND THE ACTIVE INPUT FIELD WILL BE DISPLAYED. THE INPUT WINDOW WILL NOT BE DISPLAYED. THE LOCATION OF THE FIELD WILL BE THE LOCATION SET BY THE ACTIVE INPUT WINDOW. THE COORDINATES IN THE CALL TO INPTWIND ARE IGNORED. IF AN INPUT FIELD IS PLACED AT AN UNEXPECTED SCREEN LOCATION ON A CALL TO INPTWIND AN ACTIVE INPUT WINDOW PROBABLY EXISTS WHEN IT IS NOT EXPECTED TO EXIST. Arguments: P$ is the message ( prompt ) which will be printed to the left of the input field or in the title box of the window, if one is specified. If P$ is preceded by a "@" it will be centered in the title box. CODE$ sets the type of input field and may equal the following. "A" ------ Alpha/numeric. All standard keys are active. "U" ------ Alpha/numeric. Upper case. "L" ------ Alpha/numeric. Lower case. 56 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. "D" ------ Date. A date field it can not be exited unless the date is valid or the field is blank. The number keys are active. Depending on the date format specified in the call to INPTINPT, the ".", "/" or "-" key will be active also. Valid dates range from 01/01/1901 to 12/31/2099, if the width of the date field is 10, or 01/01/01 to 12/31/99 if the width of the date field is 8. SEE DESCRIPTION FOR DATEFORMAT% IN ROUTINE "INPTINIT". "P0" or "0" - Numeric. The value of the string desig- "P1" or "1" nates the number of decimal places that "P2" or "2" will be returned, even if more or less are "P3" or "3" entered. The field can not be exited "P4" or "4" unless the number, fixed to the specified "P5" or "5" number of decimal places will fit in the "P6" or "6" the field, or the field is blank. The number keys and minus ("-") sign are active. If the number of decimal places is not zero the decimal designator ("." or ",") is active also. The minus sign will only print in the first position of the field. If a decimal point is in the field another one can not be entered until the previous one is deleted. "PR" or "R" - Real number. All numeric keys, the minus sign ("-"), and decimal designator are active. The same rules apply as for 0 - 6 decimal place numbers. The number is not fixed to a specified number of decimal places, however. NOTE: A NUMERIC FIELD WILL BE PADDED WITH LEADING ZEROS IF CODE$ CONTAINS A "P". EXAMPLE: CODE$ = "3P" --- This allows numeric input. It will return the data expanded, or truncated to, 3 digits after the decimal point and padded with leading zeros. TR% is the top row of the field or window. If a window is designated, TR% must be set to allow the entire input window fit on the display or an error will be reported. Setting TR% to 100 centers the field, or window, top to bottom on the display. LC% is the left column. If a window is designated, LC% must equal 1 to 76 . With no window LC% must equal 1 to 79 If LC% = 100 the field, or window, is centered left to right. If LC% is set so the input field 57 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. with a window, if specified, or with a prompt, if specified, will not fit on the screen an error will be reported. WD% is the field's width. A date field must have WD%=10 or WD%=8. A numeric field requires WD% to be from the number of ( decimal places + 1 ) to 15. For an alpha/numeric field WD% can range from 1 to 79 ( less than 79 if windowed ). WATTR% is the window's and prompts color. SEE THE COLOR ATTRIBUTE CHART IN THE APPENDIX. FATTR% is the input field's color SEE THE COLOR ATTRIBUTE CHART IN THE APPENDIX. RTRN$ is the string passed to, and returned from the input field. A numeric string can be converted to a number by using the VAL function. EXAMPLE: IF RTRN$= "123.123" IT CAN BE CONVERTED TO A NUMBER (A) WITH THE STATEMENT: A = VAL(RTRN$) A now equals 123.123 RKEY% is returned by INPTWIND. RKEY% represents the key used to exit INPTWIND and is restricted to those keys specified in the call to B4INPT ( argument INPUTEXIT$ ). RKEY% may equal the following RKEY% KEY WHICH EXITED INPTWIND 0 -- RKEY% will equal 0 if the argument INPUTEXIT$ in routine B4INPT = "VIEW" 1 to 10 F1 to F10 11 PGUP 12 PGDN 13 ENTER or the < OK > BUTTON 27 ESC or the < CANCEL BUTTON > NOTE THE FOLLOWING APPLIES TO NO BUTTON INPUT WINDOWS 14 SHIFT/TAB 15 TAB BUT% allows < OK > and < CANCEL > buttons for the input window. Buttons are selected by moving the cursor to the button using the tab or shift tab keys. If ENTER or the SPACE BAR is pressed and the cursor is on a button, the button is selected. If the mouse is released with the mouse cursor over a button, the button is 58 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. selected. If BUT% = 1 the < OK > button is displayed. If BUT% = 2 the < OK > and < CANCEL > buttons are displayed. Selecting the < OK > button simulates pressing the ENTER key on a selection (RKEY% = 13). Selecting the < CANCEL > button simulates pressing ESC (RKEY% = 27). IF BUT% = 1 the ESC key will not exit unless an "E" is included in routine B4INPT's argument INPUTEXIT$. Using buttons affects the length ( number of rows ) of the input window as follows. ( ----------- INPUT WINDOW TYPE ----------- ) UN-WINDOWED --------- WINDOWED --------- BUTTONS SINGLE LINE W/TITLEBOX WITHOUT TITLEBOX 0 1 ROW 5 ROWS 3 ROWS 1 or 2 2 ROWS 9 ROWS 7 ROWS NOTE: IF A WINDOW SHADOW IS SPECIFIED FOR WINDOWED INPUT FIELDS, THE NUMBER OF ROWS IS INCREASED BY ONE. BRDR% is the input window's border. ( SEE THE BORDER DESIGNATION CHART ). If BRDR% = 0 and BUT% = 0 a single line input field ( no window ) is generated. If BRDR% produces a title box window, the prompt (P$) is printed in the title box. 4.03 RSTRINPT ( RESTOREFLAG% ) See: Example - Input window Description: Deactivates the active input window generated by a call to routine INPTWIND. Optionally restores the display area under the input window. After a call to INPTWIND an active input window exists. Subsequent calls to INPTWIND behave differently if, on entry, an active input window exists. Argument: RESTOREFLAG% must equal 1 to restore the display area ( saved by routine INPTWIND ) under the active input window. If RESTOREFLAG% equals 0 the area under the active input window is not restored to the display. REGARDLESS OF THE VALUE OF RESTOREFLAG% ALL CALLS TO RSTRINPT DEACTIVATE THE ACTIVE INPUT WINDOW. EXAMPLES: 1. CALL RSTRINPT (1) 'DEACTIVATES ACTIVE INPUT WINDOW 'AND RESTORES DISPLAY AREA UNDER IT. 2. CALL RSTRINPT (0) 'DEACTIVATES ACTIVE INPUT WINDOW. 59 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. NOTE1: IF AN INPUT WINDOW REMAINS ON THE DISPLAY AND IT IS NOT THE ACTIVE INPUT WINDOW, RSTRINPT CAN NOT RESTORE THE DISPLAY AREA UNDER IT. RSTRINPT CAN ONLY RESTORE THE DISPLAY AREA UNDER THE ACTIVE INPUT WINDOW. NOTE2: THE ACTIVE INPUT WINDOW ( THE SAVED DISPLAY AREA ) RESIDES IN WINDOW NUMBER 21. FUNCTION WAVAIL% CAN DETERMINE IF AN INPUT WINDOW IS ACTIVE. EXAMPLE: IF WAVAIL%(21) = 0 ' An input window is active. IF WAVAIL%(21) = 1 ' An input window is not ' active. 60 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ----------------------------------------------------------------- ' SAMPLE: Input window ' IT IS ASSUMED ROUTINE SETWIND HAS BEEN CALLED.

Multi-field Input Overview The following is an overview of the procedures required to generate a MULTI-FIELD input screen. The procedures are listed in the order they must be used. 1. Call routine INPTINIT. This sets global variables for all input routines. It is only necessary to call INPTINIT once in every program. 2. Call routine SETINPT. This sets the properties for an individual MULTI-FIELD input screen. SETINPT must be called once for every MULTI-FIELD input screen. 3. Call routine MAKEFIELD to define each field in the MULTI- FIELD input screen. 4. Call routine MULTINPT to display the input fields and receive user input for an individual MULTI-FIELD input screen. For repeated calls to MULTINPT for a predefined MULTI-FIELD input screen it is not necessary to repeat steps 1, 2, and 3. Once a MULTI-FIELD input screen is defined it remains defined for subsequents calls to MULTINPT as long as a CLEAR statement has not been executed. 62 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 4.04 SETINPT ( SCRN%, DISPLEN%, EXIT$, HOTCOL% ) Description: Defines a multi-field input screen, which will be utilized by a subsequent call to routine MULTINPT. Arguments: SCRN% is the number of the screen being defined. SCRN% may range from 1 to 10. DISPLEN% is the length of the screen ( rows ) which will be in effect when the multi-field input screen for the designated screen number is called. DISPLEN% must equal 25, 43, or 50. When MULTINPT for this input screen is called the current screen rows must equal those specified in the call to SETINPT for the same input screen or an error will be reported. EXIT$ is a code for the keys, or mouse condition which will exit the multi-field input routine for the designated screen number. EXIT$ may be any combination of "0123456789EUDO". To make the function keys active place their number "1","2" etc in EXIT$. A "0" ( zero ) represents the F10 key, a "D" the PGDN key , a "U" the PGUP key and an "E" the ESC key. The letter "O" in EXIT$ will cause routine MULTINPT to be exited if the left mouse button is pressed while the mouse cursor is NOT in a field. EXAMPLE: IF EXIT$ ="03U" THE F10, F3, OR PGUP KEYS WILL EXIT THE MULTI-FIELD INPUT ROUTINE ( MULTINPT ). NOTE: If THE ESC KEY IS NOT USED AS AN EXIT KEY IT IS USED TO RETURN THE TEXT OF A FIELD IN MULTINPT TO IT'S PRE-EDITED STATE. THIS FEATURE IS DISABLED WHEN ESC IS USED AS AN EXIT KEY THE SPACE BAR CAN ALSO BE AN EXIT KEY FOR INDIVIDUAL FIELDS IN MULTINPT IF A FIELD IS A FIXED CHOICE FIELD. SEE THE DESCRIPTION FOR ARGUMENT CODE% IN ROUTINE MAKEFIELD TO USE FIXED CHOICE FIELDS. HOTCOL% sets the color of "key characters" for fields defined in subsequent calls to MAKEFIELD for the specified multi-field input screen. Key characters may be used to move the cursor to a specific field if the key character for that field is pressed. Although key characters may be used to move the cursor to an editable input field, key characters are ignored while in an editable field ( the characters are assumed to be input ). Editable input fields allow input. "Fixed choice" fields which may be used as BUTTONS or for multiple choices are not editable. 63 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 4.05 MAKEFIELD ( SCRN%, FLD%, CODE%, TR%, LC%, WD% INACTIVEATTR%, ACTIVEATTR%,MOUSEATTR%,RES$,EXTO$,HOTPOS%,CURPOS%,BRACKET%) NOTE1: THE ABOVE CALL TO MAKEFIELD MUST BE ON ONE LINE IN THE QB/QBX ENVIRONMENT. NOTE2: ROUTINE SETINPT FOR THE DESIGNATED MULTI-FIELD SCREEN NUMBER ( SCRN% ) MUST BE CALLED PRIOR TO CALLING THIS ROUTINE. Description: Makes input, fixed choice, or button fields for a multi-field input screen previously defined in call to routine SETINPT. The fields will be used in a subsequent call to MULTINPT. Arguments: SCRN% is the multi-input screen for which this routine is making a field. The multi-input screen MUST have been previously defined by a call to routine SETINPT. FLD% is the field number being made. The order in which fields are made, determine the order of input. Field number 2 can not be made unless field number one has been previously made. If a field is made for a specified multi-input screen, and the field already exists, the existing field is replaced with the new one. FLD% may range from 1 to 150. CODE% is the code for type of input field and can be set to any of the following. 0 to 6 ----- The field is numeric with the indicated number of decimal places. 10 to 16 --- The field is numeric with padded zeros. Subtract 10 to obtain the number of decimal places. 30 --------- The field is numeric. It is to be used for real numbers. 40 --------- The field is numeric and padded with leading zeros. It is to be used for real numbers. 7 ---------- The field is alpha/numeric. 8 ---------- The field is a date field. 17 --------- The field is alpha/numeric. (upper case) 27 --------- The field is alpha/numeric. (lower case) SEE ROUTINE "INPTWIND", ARGUMENT CODE$, FOR A DESCRIP- TION AND INPUT LIMITATIONS FOR FIELDS BASED ON THEIR DESIGNATION. 64 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Adding 100 to CODE% makes the field protected. A protected field will be displayed but can not be edited. A protected field can not be an Auto-advance or Auto-exit field. If a protected field is defined as an Auto-exit or Auto-advance field the definition is ignored and the field remains a protected field. Adding 1000 to CODE% makes the field an Auto-advance field. When the cursor reaches the end of an Auto- advance field, via typing a character, it moves to the next field. ( User defined order. ) Adding 10000 to CODE% makes the field an "Auto-exit" field. The multi-field input routine will be exited whenever the cursor is moved from an "Auto-exit" field. Adding 30000 to CODE% makes the field a "Fixed choice" field. Multi-field input routine, MULTINPT, will be exited if the space bar is pressed on, or if the cursor is moved from a "fixed choice" field. MULTINPT will also be exited if the mouse cursor is in a fixed choice field and the left mouse button is simultaneously released. This in makes the field an auto-exit field. The description for the procedure MULTINPT describes the details of a "fixed choice" field. Fixed choice fields provide several opportunities. 1. If a field is made a "fixed choice" field it may be used as a "button field". Routine MULTINPT is exited when the SPACE BAR is pressed while the cursor is in the field or when the left mouse button is released and the mouse cursor is in the field. This emulates buttons. EX: CODE%=30007 2. If a field is made a "fixed choice" field and also defined as protected ( CODE% = 30100 ) the field is a "mouse only selectable field". The cursor can not be moved to a "mouse only selectable field" as it protected ( 100 has been added to CODE% ). A "mouse only selectable field" may appear as < F1 = EXIT >. Routine MULTINPT will exit whenever the mouse cursor is in it and the left mouse button is released. If the field appears as < F1 = EXIT > and F1 is an "exit key" ( from routine SETINPT ) users without a mouse may exit MULTINPT by pressing F1. Users with a mouse may use the mouse or press F1 to exit. EX: CODE%=30100 3. If a field is made a "fixed choice" field it may be used for fixed choices. If the space bar is pressed while the system cursor is in the field, or if the left mouse button is released while the mouse cursor is in 65 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. the field routine MULTINPT is exited. The field may be updated with a different choice ( text ) and updated. Routine MULTINPT is then re-entered. EX: CODE%=30007 EXAMPLE: If CODE%= 11017 THEN CODE% = 10000+1000+17. THE FIELD IS ALPHA/NUMERIC ( UPPER CASE ), AUTO-ADVANCE AND "AUTO-EXIT". ** SEE THE MULTI-FIELD CODE CHART IN THE APPENDIX.** TR%, LC%, and WD% are the same as in INPTWIND. They represent the field's row position, column position and width. As in routine INPTWIND the width is dependent on the field type. ( SEE ROUTINE INPTWIND ) INACTIVEATTR% is the field's color when the field is inactive. The field is inactive when the system cursor is NOT in it. ACTIVEATTR% is the field's color when the field is active. The field is active when the system cursor is in it. MOUSEATTR% is the field's color when the field is occupied by the mouse cursor and the left mouse button is pressed. Usually "button" and "mouse selectable" fields require a different color ( from INACTIVEATTR% ) in MOUSEATTR%. RES$ defines the allowable characters in a restricted field. If the field is not set to alpha/numeric by CODE%, RES$ is ignored. Setting RES$ to "YN" and CODE% TO 17 ( UPPER CASE ) allows the field to respond to Y,y,N or n. If CODE% = 7 ( UPPER AND LOWER CASE ) and RES$ ="YN" the field is restricted to Y or N. IF CODE%=27 ( LOWER CASE ) and RES$ ="YN" the field will not allow any characters. If RES$ = "" the field is not restricted and will respond to characters predicated on the value of CODE%. NOTE: IT IS ONLY NECESSARY TO USE RES$ FOR NON-STANDARD FIELDS. SET RES$ TO "" FOR NORMAL ALPHA/NUMERIC FIELDS OR THE RESULT WILL BE EXTRA CODE AND MEMORY USAGE. IF THE FIELD IS STANDARD ALPHA/NUMERIC MAKE CODE% = 7 AND RES$ = "". THIS WILL ALLOW UPPER/LOWER CASE ALPHA/NUM- ERIC INPUT. EXAMPLE: RES$ = "0123456789-( )" THIS RESTRICTS INPUT TO CHARACTERS INCLUDED IN A PHONE NUMBER WITH THE AREA CODE. 66 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. EXTO$ sets the "exit to character" for the field. An "exit to character" defines a key, when pressed, which will exit to the field. If EXTO$ = "A" for a field and an "A" is pressed while the cursor is in a non-editable ( fixed choice ) field, routine MULTINPT is exited. MULTINPT's argument ( TOFLD% ) which points to the next active field will point to the field number with EXTO$ = "A". Make EXTO$ ="" if "exit to characters" are not used. NOTE: IF MORE THAN ONE FIELD HAS THE SAME "EXIT TO CHARACTER" ( EXTO$ ) ONLY THE FIRST FIELD IS FOUND. DO NOT USE THE SAME "EXIT TO CHARACTER" FOR MORE THAN ONE FIELD. HOTPOS% is the position of the character of text in the field which will assume the "key character" color set by routine SETINPT. This "key character" may be used as the "exit to character". If HOTPOS% = 0 or HOTPOS% is greater than the strings length a differently colored "key character" will not be displayed. HOTPOS% only applies to "fixed choice fields". CURPOS% determines the position the cursor will occupy in fixed choice fields when the field is active. If CURPOS% = 0 or CURPOS% is greater than the fields width the cursor will go to the position as specified by the call to INPTINIT. BRACKET% is used to set the first and last characters of text in the field to the color, BRACKETATTR% as defined by routine SETWIND. It is only appropriate for "fixed choice" fields. If BRACKET% = 1 the first and last character of text in the field assume the BRACKETATTR% color defined in routine SETINPT. This is only true when the field is the active field. This is useful for button field such as "< OK >". 4.06 MULTINPT ( SCRN%, TOFLD%, OPT$, FROMFLD%, RKEY%, RTRN$() SEL%) NOTE1: ROUTINE INPTINIT MUST BE CALLED AT LEAST ONCE IN ANY PROGRAM PRIOR TO CALLING THIS ROUTINE. NOTE2: ROUTINE SETINPT ( FOR THIS SCREEN - SCRN%) MUST BE CALLED SOMETIME IN THE PROGRAM PRIOR TO THIS CALL. Description: Displays input fields defined in a previous call to SETINPT. Fields are available for full editing Returns edited strings to the calling program. Arguments: SCRN% is the number ( 1 to 10 ) of the multi-field input screen to display. 67 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. TOFLD% serves two purposes. 1. When entering MULTINPT, TOFLD% determines which field will be the active field ( the one with the cursor ). It may range from one to the last field as designated by SETINPT. On entry to MULTINPT the field represented by TOFLD% is always updated. 2. When exiting MULTINPT, TOFLD% points to the next field the cursor would normally occupy. If a field is an auto-exit field and the down arrow is pressed, MULTINPT will be exited. TOFLD% will point to the field the cursor would normally occupy via the down arrow being pressed. This enables MULTINPT to be exited by an auto-exit field and re-entered at the correct field. If the field is a fixed choice field and the space bar is pressed, TOFLD% will point to the fixed choice field This is the field the cursor occupied before MULTINPT was exited. OPT$ specifies properties of the multi-field input screen. OPT$ may equal the following. "VIEW" ------ On entry MULTINPT will fill a single field or all fields with their respective data. MULTINPT is then exited. This is useful for viewing a multi-field screen and exiting routine MULTINPT. "U" ---------- This changes the normal field to field movement of the cursor when using the TAB, SHIFT TAB, RIGHT ARROW, AND LEFT ARROW keys to user defined order. User defined order is the same order as fields are defined in routine MAKEFIELD. The TAB and RIGHT ARROW keys follow user defined order ( same as ENTER or DOWN ARROW ). The SHIFT TAB and LEFT ARROW keys follow reverse user defined order ( same as UP ARROW ). ---------- All other string values for OPT$ have no effect on the multi-field input screen. FROMFLD% also serves two purposes. 1. If FROMFLD% is set to zero, MULTINPT, when entered, will update all fields. If FROMFLD%% is set from one to the last field number only the specified field is updated. This allows quick exiting from, and re- entering of MULTINPT. 68 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 2. When MULTINPT is exited FROMFLD% is set to the last field that was available for input prior to the exit. NOTE: ALTHOUGH THE MOUSE MAY MOVE THE INPUT CURSOR TO SEVERAL FIELDS PRIOR TO RELEASING THE LEFT MOUSE BUTTON, FROMFLD% POINTS TO THE LAST FIELD AVAILABLE FOR INPUT. IT DOES NOT POINT TO ANY OF THE FIELDS THE INPUT CURSOR MAY HAVE OCCUPIED WHILE THE LEFT MOUSE BUTTON WAS PRESSED. It is important to distinguish FROMFLD% from argument TOFLD% which points to the NEXT field the cursor would normally occupy. RKEY% returns a value designation for the key or feature which caused MULTINPT to be exited or auto- exited. MULTINPT exits when a valid exit key (specified in the call to SETINPT for the multi-field input screen) is pressed. MULTINPT is auto-exited whenever the cursor is moved out of an auto-exit field, or fixed choice field. MULTINPT is also auto-exited when the SPACE BAR is pressed with the cursor in a fixed choice field. RKEY% may equal: 1 to 10 Exit keys, F1 to F10, caused MULTINPT to be exited. MULTINPT was not exited by the auto-exit feature although the field the cursor occupied on exit may have been an auto-exit field. 11 ----- Exit key, PGUP, caused MULTINPT to be exited. MULTINPT was not exited by the auto-exit feature although the field the cursor occupied on exit may have been an auto-exit field. 12 ----- Exit key, PGDN, caused MULTINPT to be exited. MULTINPT was not exited by the auto-exit feature although the field the cursor occupied on exit may have been an auto-exit field. 13 ----- The RETURN key caused MULTINPT to be auto-exited. The field must have been an auto-exit field. 14 ----- SHIFT TAB or the LEFT ARROW caused MULTINPT to be auto-exited. The field must have been an auto-exit field. 15 ----- The TAB key or RIGHT ARROW caused MULTINPT to be auto-exited. The field must have been an auto- exit field. 16 ----- The UP ARROW caused MULTINPT to be auto-exited. The field must have been an auto-exit field. 69 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 17 ----- The CONTROL-HOME combination caused MULTINPT to be auto-exited. The field must have been an auto-exit field. 18 ----- The CONTROL-END combination caused MULTINPT to be auto-exited. The field must have been an auto- exit field. 19 ----- The DOWN ARROW caused MULTINPT to be auto-exited. The field must have been an auto-exit field. 20 ----- The AUTO-ADVANCE feature caused MULTINPT to be auto-exited. The field must also be an auto-exit field. This occurs when the text fills a auto- advance, auto-exit, field. 27 ----- Exit key, ESC, caused MULTINPT to be exited. MULTINPT was not exited by the auto-exit feature although field the cursor occupied on exit may have been an auto-exit field. 32 ----- The SPACE BAR caused MULTINPT to be auto-exited. The field occupied by the cursor on exit must have been a fixed choice field which is always an auto- exit field. 50 ----- The cursor was in a fixed-choice field ( code = 3xxxx ) and a field "exit to character" was pressed. ( SEE ARGUMENT EXTO$ FOR ROUTINE MAKEFIELD.) 100 ---- The mouse selected a new field. THE MOUSE WAS RELEASED IN THE NEW FIELD. The last field that was available for input was an auto-exit field. 200 ---- The mouse was PRESSED outside of a field. RKEY% can only equal 200 if argument EXIT$ from routine SETINPT specified an exit when the mouse is pressed out of a field. 300 ---- The mouse selected a new field AND the mouse was RELEASED outside of the field. The last field available for input was an auto-exit field. RTRN$() is a string array which holds the data to be edited. Elements of RTRN$() will be displayed in the appropriate fields. RTRN$(1) will be displayed in field 1 and so on. Make sure there is not a RTRN$(0) as it will not be displayed. If a field is numeric, the number to be placed in it must be converted to a string. Convert the number (A) to a string as follows: RTRN$(2) = STR$(A) 70 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. When MULTINPT is exited RTRN$() holds the data in it's edited state. On entering MULTINPT, if the field is designated as alpha/numeric and the string will not fit in the field it will be truncated to fit. If the field is numeric and a number formatted to the correct number of decimal places will not fit in the field, "*"'s will be printed. This will not pose a problem if RTRN$() is initialized via MULTINPT, as MULTINPT will not allow the user to input data longer than the field's width. If a numeric field is entered with an alpha string the string will print in the field. It is the programmer's responsibility to assure numeric fields contain numeric strings. IF A FIELD IS NUMERIC WITH 4 DECIMAL PLACES SETTING THE FIELD TO EQUAL "DOG", WILL RESULT IN DOG.0000 BEING DISPLAYED! Use caution if a field is a result of calculation, as the result may be in exponential format. EXAMPLE: A = 1 B = 14 C = A/B STR$(C) = "7.142857E-02". If the field is numeric with four decimal places and set to equal STR$(C) it will print as 7.1428, and not as .0714. To following routine corrects numbers in expoential form for both large and small numbers. A$ is the numeric string to be displayed in a field. IF INSTR(3, A$, "+") THEN A$ = "9999999999999999" REM: THE NUMBER WAS TOO LARGE ( EX: 2.2D+22 ). SET TO REM: "9999999999999999" AND "*"'s WILL BE DISPLAYED. IF INSTR(3, A$, "-") THEN A# = VAL(A$): A# = A# + SGN(A#): A$ = STR$(A#) IF ABS(A#) > 1 THEN A$ = MID$(A$, INSTR(A$, ".")) IF A# < 1 THEN A$ = "-" + A$ ELSE A$="0" END IF END IF REM: THE NUMBER WAS TOO SMALL. IF A$ = "3.33D-4", REM: A$ WILL NOW = ".000333" SEL% returns a value if the exit from routine MULTINPT was caused by the mouse selecting a "mouse only selectable field". SEL% will equal the field number of the "mouse only selectable field" selected by the mouse and argument RKEY% will equal 100 indicating the left 71 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. mouse button was released in the field. When MULTINPT is exited by a "mouse only selectable field" argument TOFLD% points to the last field occupied by the system cursor. "Mouse only selectable fields" can not be occupied by the system cursor. 72 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. --------------------------------------------------------------- FIELD EDITING FEATURES FOR "MULTINPT" AND "INPTWIND" ( * = AVAILABLE FOR "MULTINPT" ONLY. ) --------------------------------------------------------------- KEY FUNCTION SPACE BAR ERASES FIELD - IF IT IS THE FIRST KEY PRESSED. *UP ARROW MOVES THE CURSOR FROM FIELD TO FIELD AS DETER- *DOWN ARROW MINED BY THE ORDER DEFINED IN "SETINPT."

NOTE1: THE FIELD TO UPDATE MUST BE DISPLAYED ON THE SCREEN. IF IT IS NOT DISPLAYED THIS ROUTINE WILL PRINT IT'S TEXT AT THE LOCATION THE FIELD WOULD NORMALLY OCCUPY. NOTE2: ONLY THE FIELD IS UPDATED. IT IS THE PROGRAMMER'S RESPONSIBILITY TO UPDATE THE ELEMENT OF THE ARRAY HOLDING THE FIELD'S DATA IN ROUTINE MULTINPT. ( SEE ARGUMENT RTRN$() IN ROUTINE MULTINPT ) Arguments: SCRN% is the screen number ( 1 to 10 ) of the multi-field input screen. ( SEE ROUTINES SETINPT AND MULTINPT ). If SCRN% is not a valid screen number or it is a screen number which has not been pre-defined by routine SETINPT the call to UPDATEFIELD is ignored. FLD% is the field number of the field to update. FLD% must be a valid field number for the specified multi-input screen ( SCRN% ) or the call to UPDATEFIELD is ignored. TEXT$ is the text to print in the field. 4.08 GETANS (PROMPT$,CHOICE$,ANS$,TR%,LC%,WATTR%,FATTR%,BORDER%) Description: Generates a prompt with an optional window and pauses, waiting for a single key reply. The key may be any key or an individual key selected from a definable list. The prompt may be windowed or on a single line. The key pressed may, or may not be displayed. If it is displayed ENTER must be pressed to finalize the selection is optional. NOTE: THERE ARE TWO MODES OF OPERATION FOR THIS ROUTINE. SEE THE DESCRIPTION FOR THE ARGUMENT ANS$ FOR DETAILS. Arguments: PROMPT$ is the prompt ( i.e. Press any key ) or question ( i.e. Are you sure? Y/N ). It may be optionally windowed ( SEE BORDER% ). The width of the window is determined by the length of PROMPT$. If PROMPT$ is too long making the window, or prompt, too wide to fit on the screen an error will be reported. CHOICE$ is the valid keys the user can press to exit GETANS. If CHOICE$ = "" any key will exit. This would be appropriate if PROMPT$ = "Press any key". If CHOICE$ = "YN" then the "Y", "y", "N" or 74 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. "n" keys will exit GETANS. The ESC key will always exit regardless of CHOICE$. ANS$ serves two purposes. On entry ANS$ determines the mode of operation for routine GETANS. There are two modes of operation for this routine. 1. If argument ANS$ = "" on entry, as soon as a valid key is pressed the routine is exited. EXAMPLE: ANS$ = "" CALL GETANS ( PROMPT$, "YN", ANS$ ...... As soon a "Y" or "N" is pressed the routine is exited with the key pressed returned in ANS$ 2. If argument ANS$ equals any letter on entry the letter is displayed in the get answer window to the right of the prompt. The user may press any valid key predicated on argument CHOICE$. The letter represented by the valid key is displayed in the get answer window. The user must press ENTER to accept the choice. EXAMPLE: ANS$ = "N" CALL GETANS ( PROMPT$, "YN", ANS$........ On entry an "N" will appear after the prompt. If a "Y" is pressed it will appear after the prompt. The user must press ENTER to exit the routine with the displayed letter returned in ANS$. On exit ANS$ holds the key pressed. It is returned in upper case. If CHOICE$ = "" then ANS$ = "". If ESC is pressed CHR$(27) is always returned in ANS$. TR% is the top row. See MAKEWIND LC% is the left column. See MAKEWIND WATTR% is the window's and text's color designation. See MAKEWIND. Although it is permissible to set ATTR% > 127 to make the border flash the text will not flash. FATTR% is the field's ( if one exists ) color. If ANS$ equals a letter, on entry, the letter is displayed next to the prompt. The color of this letter is set by FATTR%. 75 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. BORDER% is the window's border designation. Title boxes ( BORDER% > 42 ) are not permitted. Set BORDER% to 0 for no window ( prompt only ). SEE THE BORDER DESIGNATION CHART. EXAMPLE OF A CALL TO GETANS: ANS$ = "" CALL GETANS ("Are you sure? Y/N", "YN", ANS$, 100, 100, 240, 11) ( Above must be on one line. ) A window will be generated with the text "Are you sure? Y/N" printed in it. With TR% and LC% set to 100 the window will be centered on the screen ( See MAKEWIND ). ATTR% = 240, therefore, the window will be white with black text and a black flashing border. The user may press the N, n, Y, y, or ESC keys to exit. The key pressed will be returned to GETANS in the argument ANS$. 4.09 CHOICEWIND% (T$,TXT$(),CH$(),TR%,LC%,ATTR%,HATTR%,ESC%,BRDR%) ( CHOICEWIND% is a function ) NOTE: ROUTINES INPTINIT AND SETWIND MUST BE CALLED AT LEAST ONCE IN ANY PROGRAM PRIOR TO CALLING THIS ROUTINE. Description: Displays a window containing text. The window also displays up to ten choices. A choice may be selected by using the TAB or SHIFT/TAB key to move the cursor to the choice and pressing ENTER or the SPACE BAR. A choice may also be selected by RELEASING the left mouse button while the mouse cursor is on the choice. The choice window's height is determined by the number of lines of text in it. The choice window's width is determined by the longest line of text or the width of the choices, whichever is greatest. CHOICEWIND% returns the number of the selection made by the user, or 27 if ESC is pressed and argument ESC% > 0. Arguments: T$ is the windows title. Based on the value of BRDR% ( SEE MAKEWIND ), T$ will print in the window's title box or on the window's top border. TEXT$() is an array holding the text for each line in the choice window. TEXT$(1) prints as line one in the choice window. TEXT$(2) prints as the second line in the choice window. Each element of TEXT$() represents a line in the choice window. NOTE: TEXT$() DETERMINES THE NUMBER OF LINES IN THE CHOICE WINDOW. IF TEXT$()'s UPPER BOUND IS TEN ( EX: REDIM 76 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. TEXT$(10) ), TEN LINES WILL BE PRINTED IN THE CHOICE WINDOW. If TEXT$()'s UPPER BOUND IS ZERO ( EX: REDIM TEXT$(0) ), NO LINES OF TEXT WILL PRINT IN THE CHOICE WINDOW. THIS MAY BE APPROPRIATE IF THE CHOICE WINDOW'S TITLE ( ARGUMENT T$ ) IS THE ONLY PROMPT REQUIRED. The following applies to TEXT$(); 1. TEXT$ must ALWAYS be dimensioned prior to any call to CHOICEWIND%. If no text is used TEXT$() must be dimensioned to zero. ( EX: REDIM TEXT$(0) ) 2. If an element of TEXT$() has a "@" as the first character, the text will be centered in the choice window. 3. If an element of TEXT$() = "" a blank line will be printed in the choice window. 4. If an element of TEXT$() = "-" a segmenting single line will print across the choice window. NOTE: TEXT$() IS ERASED BY THE CALL TO CHOICEWIND TO CONSERVE MEMORY. TEXT$() MUST BE REDIMENSIONED PRIOR TO ANY CALL TO CHOICEWIND. CH$() is an array holding the choices for the choice window. Each choice is automatically bracketed. If CH$(1) = "OK", it will be displayed as "< OK >". One to 10 choices are permitted NOTE: CH$() IS ERASED BY THE CALL TO CHOICEWIND TO CONSERVE MEMORY. CH$() MUST BE REDIMENSIONED PRIOR TO ANY CALL TO CHOICEWIND. TR% is the choice window's top row position. If TR% = 100 the choice window is centered top to bottom on the display. LC% is the choice window's left column position. If LC% = 100 the choice window will be centered left to right on the display. ATTR% is the color of the choice window and it's text. HATTR% if not zero allows "key character" selections and sets the key character color of the items in CH$(). The key character is always the first character of each element of CH$(). If HATTR% = 0 key characters are not used. 77 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ESC% allows CHOICEWIND% to exit if the ESC key is pressed. If ESC% = 1 and ESC is pressed CHOICEWIND% will exit with a value of 27. If ESC% = 0 and ESC is pressed CHOICEWIND% will not be exited. BRDR% is the choice window's border. ( SEE ARGUMENT BORDER% FOR ROUTINE MAKEWIND. ). BRDR% may NOT equal zero. 4.10 CHOICEBAR% (CH$(), TR%, LC%, WD%, ATTR%, HATTR%, EX$ ) ( CHOICEBAR% is a function. ) NOTE: ROUTINE INPTINIT MUST BE CALLED AT LEAST ONCE IN ANY PROGRAM PRIOR TO CALLING THIS ROUTINE. Description: Displays one to ten choices on a single line on the display. A choice may be made by moving the cursor to the choice using the TAB or SHIFT/TAB keys and pressing the ENTER key or the SPACE BAR. If the left mouse button is released while the mouse cursor is on a choice the selection is made. CHOICEBAR% returns the following. 0 --------- On entry argument EX$ = "VIEW" routine CHOICEBAR is displayed and exited. 1 TO 10 --- Choice 1 to 10 was selected. Choice 1 is the leftmost choice, 2 is to the right of 1 etc. 11 --- PGUP is an exit key and PGUP was pressed. 12 --- PGDWN is an exit key and PGDWN was pressed. -1 TO -10 -- F1 to F10 are exit keys and F1 to F10 was pressed. 27 --- ESC is an exit key and ESC was pressed. 15 --- TAB is an exit key and TAB was pressed. 14 --- SHIFT/TAB is an exit key and SHIFT/TAB was pressed. 200 --- The left mouse button was pressed outside of choicebar selections and an "O" was included in argument EXIT$ Arguments: CH$() is an array holding the choices for the choice bar. Each choice is automatically bracketed. If CH$(1) = "OK", it will be displayed as "< OK >". One to 10 choices are permitted. TR% is the choice bar's top row position. LC% is the choice bar's left column position. WD% is the width of the choice bar. The choices are automatically spaced in the choice bar's width. 78 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ATTR% is the color of the choice bar and it's text. HATTR% if not zero allows "key character" selections and sets the key character color of the items in CH$(). The key character is always the first character of each element of CH$(). If HATTR% = 0 key characters are not used. EX$ is used to provide additional exit keys or alternate ways to exit CHOICEBAR%. EX$ may equal any combination of "0123456789UDETO" or "VIEW". Each character in EX$ provides a means of exiting CHOICEBAR as indicated by the following list. "0" ---------- The F10 key exits. "1" to "9" --- The F1 to F9 keys exit. "U" ---------- The PAGE UP key exits. "D" ---------- The PAGE DOWN key exits. "E" ---------- The ESC key exits. "T" ---------- The TAB key and SHIFT/TAB combination exit. "O" ---------- Pressing the left MOUSE button while the mouse cursor is out of all choices exits. "VIEW" ------- This displays the choicebar only. Routine CHOICEBAR is dispalyed and exited. NOTE: THE DISPLAY AREA UNDER A CHICEBAR IS NOT SAVED. BY PLACING THE CHOICEBAR IN AN EXISTING WINDOW, THIS LIMITATION IS NEGATED. WHEN ROUTINE RSTRWIND IS CALLED FOR THE EXISTING WINDOW THE AREA UNDER THE WINDOW IS RESTORED. 79 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ***** DIRECTORY ROUTINES ***** Directory routines compliment features included with QB 4.5 BASIC 7.1 ( PDS ) and VB for DOS . Procedures to find the current disk, current path, disk capacity, and disk space available are supplied with WINDOWS R-E-Z. Also included are routines to find the directory of any disk or path. In addition a file's size, date, time, and attributes can be found. 5.00 GETDISK% ( THIS IS A FUNCTION ) Description: Returns the default disk drive. Returns 1 drive A:, 2 for B:, 3 for C:, 4 for D: etc. Argument: None NOTE: DECLARE THIS FUNCTION IN ANY MODULE WHIC USES IT. 5.01 FINDPATH$ ( THIS IS A FUNCTION ) NOTE: ALWAYS TRAP FOR DISK ERRORS PRIOR TO CALLING THIS FUNCTION. SEE SECTION " MAKING A DIRECTORY SCROLL WINDOW" Description: Returns the current path (directory) in the following format, alway starting with the drive letter, DRIVE:\SUB-DIRECTORY\SUB-DIRECTORY.... NOTE: DECLARE THIS FUNCTION IN ANY MODULE WHIC USES IT. 5.02 SETDISK (DRIVE%, BADFLAG%) Description: Changes the default drive. Arguments: DRIVE% is the drive designation. DRIVE% = 1 for drive A:, 2 for B:, 3 for C:, etc. BADFLAG% = 1 if DRIVE% is less than 1 or greater than the number of logical drives. BADFLAG% = 0 if DRIVE% is in the range from 1 to the number of logical drives in the system. NOTE: A SYSTEM WITH A FLOPPY DRIVE FOR DRIVE A: AND A HARD DISK FOR DRIVE C: HAS 3 LOGICAL DRIVES. THEREFORE, BADFLAG% WILL = 0 IF DRIVE% = 1 TO 3 EVEN THOUGH A PHYSICAL DRIVE B: DOES NOT EXIST. ATTEMPTS TO ACCESS DRIVE B: MAY RESULT IN THE DOS MESSAGE. "Place a disk in drive B: and press any key" BEING DISPLAYED. 80 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 5.03 DISKSIZE (DRIVE%, SIZE&, FREE&) NOTE: ALWAYS TRAP FOR DISK ERRORS PRIOR TO CALLING THIS ROUTINE. SEE SECTION " MAKING A SCROLL DIRECTORY WINDOW". Description: Retrieves disk space and disk free space. Arguments: DRIVE% is the drive designation. It follows the same rules as detailed in SETDISK. The note for SETDISK applies. SIZE& is the size in bytes of disk space. FREE& is the size in bytes of free disk space. NOTE: THE ARGUMENTS FOR SIZE AND FREE SPACE ARE LONG INTEGERS. ANY VARIABLE USED TO REPRESENT THEM MUST BE DESIGNATED AS A LONG INTEGER ( FOLLOWED BY A "&" SIGN ) OR A PARAMETER MIS-MATCH WILL BE REPORTED. 5.04 FINDDIR (PATH$, TYP$, FILE%) NOTE # 1: THE FOLLOWING MUST BE PLACED BEFORE ANY EXECUTABLE STATEMENTS IN ANY MODULE CALLING "FINDDIR" TYPE DIREC SIZE AS LONG DATE AS STRING * 10 TIME AS STRING * 6 ATTR AS INTEGER END TYPE COMMON SHARED /DIRECTORY/ DIREC$(), DIRINFO() AS DIREC NOTE # 2: ALWAYS TRAP FOR DISK ERRORS PRIOR TO CALLING THIS ROUTINE. SEE SECTION " MAKING A SCROLL DIRECTORY WINDOW" Description: Puts the directory listing of the specified path in an array, DIREC$(). If a long directory search is requested the files size, date, time and attributes are also placed in array, DIRINFO(). The arrays MUST be defined as explained above in NOTE # 1. Arguments: PATH$ is the path for the directory listing search. It must be in the same format as returned by the procedure FINDPATH. It may be expanded to restrict the search. Wildcards are permitted. EXAMPLE: IF PATH$ = "C:\TEST\*.BAS", THE SEARCH WILL 81 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. FIND FILES IN DRIVE C:, SUB-DIRECTORY "TEST", WITH THE EXTENSION ".BAS". TYP$ restricts or expands the search to include files with specified attributes. An "L" in TYP$ tells FINDDIR to make a long directory search. The file's size, date, time and attributes are found in a long directory search, in addition to the files name, TYP$ may contain any combination of the following: A - file's archive bit is set H - hidden files S - system files R - read only files D - sub-directory listings V - volume entry O - no file attribute L - long directory search - SEE ABOVE EXAMPLE: IF TYP$ = "HS" ONLY HIDDEN AND SYSTEM FILES WILL BE FOUND. FILE% is the number of files found. FILE% = 0 if no files were found. If files are found their names are placed in the array, DIREC$(). A long directory search places the file's size, date, time and attribute designation in DIRINFO(). DIREC$(1) = The name of first file found. DIRINFO(1).SIZE = The size of the file. DIRINFO(1).DATE = The files creation or last update date. DIRINFO(1).TIME = The files creation or last update time. DIRINFO(1).ATTR = The files attribute designation. The following describes DIRINFO(1).ATTR; IF DIRINFO(1).ATTR AND 1 the file is a read only file. IF DIRINFO(1).ATTR AND 2 the file is a hidden file. IF DIRINFO(1).ATTR AND 4 the file is a system file. IF DIRINFO(1).ATTR AND 8 the entry is a volume entry. IF DIRINFO(1).ATTR AND 16 the entry is a sub-directory. IF DIRINFO(1).ATTR AND 32 the files archived bit is set. IF DIRINFO(1).ATTR = 0 the file has no attribute. NOTE: WHEN FINDDIR IS CALLED THE ARRAY, DIREC$() IS AUTOMATICALLY DIMENSIONED TO THE NUMBER OF FILES FOUND. THE ARRAY, DIRINFO() IS ALSO DIMENSIONED TO THE NUMBER OF FILES FOUND PROVIDING THE DIRECTORY SEARCH IS A LONG DIRECTORY SEARCH. EACH FILE FOUND USES ABOUT 16 BYTES OF MEMORY PLUS AN ADDITIONAL 22 BYTES IF THE DIRECTORY 82 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. SEARCH IS LONG. TO RECLAIM THE MEMORY ( AFTER USING THE INFORMATION RETURNED BY THE CALL TO FINDDIR ) THE ARRAYS MUST BE ERASED VIA THE STATEMENT: ERASE DIREC$, DIRINFO 83 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ***** MAKING A DIRECTORY SCROLL WINDOW ***** REM: THIS EXAMPLE FINDS THE DIRECTORY LISTING OF ALL FILES REM: WITH THE ARCHIVE BIT SET IN DRIVE A.

NOTE: MOST OF THESE ROUTINES ARE ASSEMBLY ROUTINES. ALWAYS PLACE THEM IN DECLARE STATEMENTS IN ANY MODULE WHICH USES THEM. THIS WILL ASSURE ARGUMENT MATCHING AND PREVENT ACCIDENTAL PROGRAM "CRASHES". 6.00 GETAKEY% Description: GETAKEY% is a function. It returns a value for the next character in the keyboard buffer or zero if no character is in the keyboard buffer. If the key pressed represents a standard ASCII/IBM character, the code for the character ( 1 to 255 ) is returned in GETAKEY%. If the key pressed produces an extended scan code such as the up arrow, the extended scan code for the key multiplied by 256 is returned in GETAKEY%. GETAKEY% returns 18432 ( 72 * 256 ) for the up arrow. For those keys which produce an extended scan code over 127, such as CTRL-PGUP ( 132 ), GETAKEY% returns a negative value. SEE THE GETAKEY CODE CHART IN THE APPENDIX. ------------------------------------------------------- 'EXAMPLE: WAITS FOR RETURN, "A", DOWN ARROW, OR END.

END -------------------------------------------------------- 86 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 6.01 CLEARKB Description: Clears all characters from the type ahead keyboard buffer. Arguments: None 6.02 MOUSEON% (ISON%) ( FUNCTION ) Description: Sets the mouse status and initializes the mouse. Returns 1 if the mouse driver is present, the mouse hardware is present, and the mouse is set on by argument ISON%. If the preceding conditions are not true MOUSEON% returns 0. Arguments: ISON% turns the mouse off or attempts to turn the mouse on. If ISON% = 1, and the mouse driver and hardware are present, the mouse will be turned on. The mouse cursor will be visible and positioned on row one and column one of the display. If ISON% = 0 the mouse is turned off, and the mouse cursor is hidden. 6.03 MOUSEHIDE Description: Hides the mouse cursor. Decrements the mouse "visibility flag" by one. ( SEE MOUSESHOW ) Arguments: None 6.04 MOUSESHOW Description: Displays the mouse cursor. Increments the mouse "visibility flag" by one. NOTE: FOR EVERY CALL TO MOUSEHIDE A SUBSEQUENT CALL TO MOUSESHOW IS REQUIRED TO DISPLAY THE MOUSE CURSOR. TWO CONSECUTIVE CALLS TO MOUSEHIDE REQUIRE TO CONSECUTIVE CALLS TO MOUSESHOW TO DISPLAY THE MOUSE. THE REVERSE IS NOT TRUE. EXAMPLE: ( ASSUMES THE MOUSE CURSOR IS VISIBLE ) CALL MOUSEHIDE ' Mouse cursor hidden - "visibility ' flag" is decremented. CALL MOUSEHIDE ' "visibility flag" decremented again. CALL MOUSESHOW ' "Visibility flag" incremented. Mouse ' is still hidden. 87 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. CALL MOUSESHOW ' "Visibility flag" incremented. Mouse is ' now displayed. 6.05 MOUSEROW% ( NOTE: THIS IS A FUNCTION ) Description: Returns the row position of the mouse cursor. Arguments: None 6.06 MOUSECOL% ( NOTE: THIS IS A FUNCTION ) Description: Returns the column position of the mouse cursor. Arguments: None 6.07 MOUSEPOS ( ROW%, COLUMN% ) Description: Moves the mouse cursor to a specified position. NOTE: IT IS POSSIBLE TO MOVE THE CURSOR OFF OF THE DISPLAY Arguments: ROW% is the row position. COLUMN% is the column position. 6.08 MOUSELIMIT ( TOPROW%, BOTTOMROW%, LEFTCOL%, RIGHTCOL% ) Description: Sets the bounds for mouse cursor movement. Arguments: TOPROW% is the top row limit of movement for the mouse cursor. BOTTOMROW% is the bottom row limit of movement for the mouse cursor. LEFTCOL% is the left column limit of movement for the mouse cursor. RIGHTCOL% is the right column limit of movement for the mouse cursor. 6.09 LBUTTON% ( NOTE: THIS IS A FUNCTION ) Description: Returns the status of the left mouse button. If the left mouse button is pressed LBUTTON% = 1. If the left mouse button is not pressed LBUTTON% = 0. Arguments: None 88 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. 6.10 RBUTTON% ( NOTE: THIS IS A FUNCTION ) Description: Returns the status of the right mouse button. If the right mouse button is pressed RBUTTON% = 1. If the right mouse button is not pressed RBUTTON% = 0. Arguments: None 6.11 MOUSEINWIND% ( WIND% ) ( NOTE: THIS IS A FUNCTION ) Description: Returns a value signifying if the mouse cursor is in a specified window. The returned values may equal the following. 0 -- The mouse cursor is not in the specified window or the specified window does not exist. 1 -- The mouse cursor is on the TOP border ( including the corners ) of the specified window. 2 -- The mouse cursor is on the RIGHT border ( excluding the corners ) of the specified window. 3 -- The mouse cursor is on the BOTTOM border ( including the corners ) of the specified window. 4 -- The mouse cursor is on the LEFT border ( excluding the corners ) of the specified window. 5 -- The mouse cursor is in the interior of the specified window. NOTE: MOUSEINWIND% RETURNS A VALUE BASED ON THE WINDOW'S COORDINATES. IT IS THE PROGRAMMERS RESPONSIBILITY TO ASSURE THE SPECIFIED WINDOW IS VISIBLE WHEN MOUSEINWIND% IS CALLED. Argument: WIND% is the number of the window; 0 to 20 represent standard windows. 21 represents the INPUT window, if one is active. 23 represents the PULLDOWN window, if one is active. 24 represents the PULLDOWN menubar, if one is active. 6.12 MOUSEINMULT% ( MULTSCRN% ) ( NOTE: THIS IS A FUNCTION ) Description: Returns the field number of a specified multi-field input screen the mouse cursor occupies or zero if the mouse cursor is not in a field. 89 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. NOTE: IT IS THE PROGRAMMERS RESPONSIBILITY TO ASSURE THE SPECIFIED MULTI-FIELD SCREEN IS DISPLAYED. IF IT IS NOT AND IT EXISTS, MOUSEINMULT% RETURNS A VALUE AS IF IT IS DISPLAYED. Argument: MULTSCRN% is a multi-field input screen defined by previous calls to SETINPT and MAKEFIELD, and displayed by MULTINPT. If MULTSCRN% is out of range ( 1 to 10 ) or set to an undefined input screen, MOUSEINMULT% returns zero. 90 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. **** INFO-LINE ROUTINES ***** These routines allow the programmer to set up and print in an info-line at any location on the screen. The info-line can be used to print messages, instructions, or a prompt. Used in conjunction with routines PULLDOWN and SCRLWIND these routines will change the message in the info-line as the scroll bar is moved through the selections in the pulldown and scroll windows. 7.00 INFOLINE ( TR%, LC%, WD%, ATTR% ) Description: Set up routine for routines PRINTINFO, INFOFIXED, AND RSTRINFO. Sets the coordinates and the color for the info-line. Defines the fixed info-string to equal "" ( SEE: INFOFIXED ). Makes the info-line active. Saves the display area specified by TR%, LC%, and WD%. This area may be restored by calling routine RSTRINFO. INFOLINE DOES NOT PRINT OR DISPLAY THE INFO-LINE. THIS IS ACCOMPLISHED BY ROUTINE PRINTINFO. Routine PRINTINFO is incorporated in routines PULLDOWN and SCRLWIND. It may also be used prior to calling other routines. ( SEE: Examples - Info-line routines ) NOTE: IF AN INFO-LINE IS ACTIVE A CALL TO INFOLINE DOES NOTHING EXCEPT TO CHANGE THE COLOR (IF IT IS DIFFERENT) OF THE INFO-LINE FOR SUBSEQUENT CALLS TO PRINTINFO. THE INFO-LINE IS DEACTIVATED VIA A CALL TO RSTRINFO. Arguments: TR% is the top row position of the info-line. LC% is the left column position of the info- line. If LC% + WD% > 81 an error will be reported. WD% is the info-lines width. If WD% + LC% > 81 an error will be reported. ATTR% is the info-lines color ( SEE THE COLOR ATTRIBUTE CHART ). ATTR% must range from 1 to 255 or it is adjusted to ATTR% AND 127. 7.01 PRINTINFO ( INFO$ ) Description: Displays the info-line and prints in same. The info-line must have been made active by a previous call to INFOLINE. If a fixed info-string has been previously defined by a call to routine INFOFIXED, PRINTINFO adds it's text to the fixed info-string and displays the result in the info-line ( SEE: INFOFIXED ). If an info-line is not active PRINTINFO does nothing. ( SEE: Examples -Info-line routines. 91 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. Argument: INFO$ is the string which will print in the info-line. If a fixed info-string has been defined by routine INFOFIXED, INFO$ is added to the fixed info-string with the result printing in the info-line. If the length of the fixed info-string plus the length of INFO$ will not fit in info-line defined by routine INFOLINE it is truncated to fit. 7.02 INFOFIXED ( FIXEDINFO$ ) Description: Defines a fixed info-string which will print every time routine PRINTINFO is called. As PRINTINFO is called for every entry in a scroll or pulldown window, INFOFIXED is useful for these routines. The info-line must be active or INFOFIXED does nothing. ( SEE: Examples - Info-line routines ) Argument: FIXEDINFO$ is the fixed info-string. It will remain the fixed info-string until routine RSRTINFO is called with argument DELFLAG% = 1 ( SEE: RSTRINFO ). The fixed info-string may be also disabled by calling INFOFIXED with FIXEDINFO$ equal to "". 7.03 RSTRINFO ( DELFLAG% ) Description: Restores the display area under the info- line. This area was saved by a previous call to INFOLINE. If the info-line is not active RSTRINFO does nothing. (SEE: Examples - Info-line routines. ) Argument: DELFLAG% is set to 1 to deactivate the info- line. If DELFLAG% = 1 the display area saved by routine INFOLINE is restored to the display. An info-line will no longer be active. If DELFLAG% = 0 the info-line remains active. The saved display area is restored. The saved display are remains in window memory, however. NOTE: THE SAVED DISPLAY AREA RESIDES IN WINDOW NUMBER 25. FUNCTION WAVAIL% CAN DETERMINE IF THE INFOLINE IS ACTIVE. EXAMPLE: IF WAVAIL%(25) = 0 ' The info-line is active. IF WAVAIL%(25) = 1 ' the info-line is not active. 92 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ----------------------------------------------------------------- ' Example: Info-line routines ' THIS EXAMPLE WILL NOT RUN AS THE CALLS TO INPTWIND, SCRLWIND, ' AND PULLDOWN ARE NOT COMPLETE.

EVENT TRAPPING -------------- Additional library files have been included which allow event trapping ( SEE THE SECTION TITLED FILES ). These libraries may be used for programs which do not require event trapping also. It is important to note, however, that additional code will be added to programs that are compiled from the QB/QBX/VBDOS environments, even if event trapping is not used. QuickBASIC 4.5, BASIC 7.1, and VBDOS detect event trapping capabilities in the *.QLB library and add the /W or /V switch to the compiler ( BC.EXE ) when modules are compiled from the programming environment; even if the modules do not use event trapping. This adds extra code to the program and reduces it's speed. If modules not are compiled and linked from the command line the /W and /V switches are not required for modules not using event trapping. If modules will be compiled from the programming environment and event trapping is not used, use the libraries supplied which do not include event trapping. THESE LIBRARIES ARE NOT SUPPLIED IN THE UNENHANCED VERSIONS. When event trapping is used care should be taken to assure that "exit keys" for routines do not conflict with keys trapped via event ( key ) trapping. For example if the F1 key is used as an "exit key" for routine MULTINPT and the F1 key is trapped via event trapping two events will occur. The event trapping routine will be executed for the F1 key pressed event, and routine MULTINPT will be executed as F1 is designated as an "exit key". 102 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved.

Errors The following is a listing of the errors WINDOWS R-E-Z will detect. ERROR # DESCRIPTION ------------------------------------------------------------ ERROR 1 There is no active window. SCRLWIND, RESAVE CLRWIND, PRINTW, PRINTWHOT, LINEW, NEWCOLOR, and BOXW require an active window. ERROR 2 SETWIND has not been called to initialize window memory. This error will also be reported if the program uses a CLEAR statement and SETWIND has not be called to re-initialize window memory. ERROR 3 A window number has been specified which is out of range for the calling routine. Window number 20 is the maximum window number for all routines. Window number 1 is the minimum window number for SAVEWIND, DELWIND, RESAVE and RSTRWIND. Window number 0 is the minimum window number for MAKEWIND and CHNGWIND. ERROR 4 The window will not fit on the screen or the window is too small. The left column plus the window's width makes the window too wide or the top row plus the number of rows makes the window too tall. The left column and top row must be greater than 0. The width and number of rows must be greater than 2. The left column or row are out of permissible range. GETANS makes a window with a width predicated on the width of the prompt. INPTWIND makes a window with a width based on the length of the prompt plus the width of the input field. Input windows with < OK > and < CANCEL > buttons require additional rows. PULLDOWN windows have a width based on the longest item in the pulldown window's list. The number or rows in a pulldown window are based on the number of selections and segmenting lines in same. 106 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. CHOICEWIND makes a window with a width based on the longest line of text in it or the width of the choices in it. The length is based on the number of lines of text in the choice window. This error is reported for INPTWIND and GETANS if no window is specified ( BORDER%=0 ) and the width of the prompt and/or field will not fit on the screen. ERROR 5 The border designation is not valid for the calling routine. GETANS does not allow title windows. PULLDOWN does not allow title windows and only allows right-bottom shadows. SEE THE BORDER DESIGNATION CHART. ERROR 6 A request was made to CHNGWIND to make the active window a non-existent window or a window saved via SAVEWIND. The active window can only be a window generated by MAKEWIND. ERROR 8 An window specified in a call to MAKEWIND or SAVEWIND previously existed. A window must be deleted via a call to DELWIND or RSTRWIND before the number assigned to it can be used again. This error will not be reported for window number 0 as it is not saved. ERROR 9 A call to INPTINIT was not made to initialize input memory. INPTINIT must be called once in every program prior to calling routines INPTWIND MULTINPT, CHOICEWIND, CHOICEBAR or SCRLWIND with buttons. If a CLEAR statememt is executed, INPTINIT must be called again. ERROR 11 A bad row number was specified in a call to PRINTW, PRINTWHOT, LINEW or BOXW. The row number must be greater than 0. PRINTW and PRINTWHOT allow print on the bottom border. LINEW does not. The string specified in a call to PRINTW or PRINTWHOT will not fit in the window due to it's length or it's left column ( start print ) position. The entire box in a call to BOXW will not fit in the active window. BOXW does not allow row or column value to equal 100 to center then box. 107 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ERROR 12 The position or width of the info-line in a call to INFOLINE or PRINTINFO is illegal. The position or width of the menubar in a call to SETPULL or PULLDOWN is illegal. The position or width of the choicebar in a call to CHOICEBAR is illegal. The left column position is out of range. A combination of the left column position plus the specified width will not allow the info-line, menubar or choicebar to fit on one line. The menubar selection or choicebar selections will not fit in the specified width. The minimum row position, left column position and left column plus the width are checked on the calls to INFOLINE SETPULL, and CHOICEBAR. The maximum row position is checked on the calls to PRINTINFO, PULLDOWN and CHOICEBAR and is based on the active number of display rows at the time of the call. ERROR 13 This is an array dimension error. The array ( LIST$() ) in a call to SCRLWIND has a lower dimension greater than 1 or an upper dimension less then the number of entries ( ENTRIES% ) in the list. The array ( RTRN$() ) specified in a call to MULTINPT has a lower dimension of greater than one or an upper dimension less than the number of fields in the multi-field input screen. ERROR 14 A routine was called with an illegal number of selections. The number of entries ( selections ) in a call to SCRLWIND must be greater than one. The number of selections in an "EXTENDED" scroll window exceeds the number or interior rows in the scroll window. The number of selections in a pulldown window's menubar, set by routine SETPULL must equal one to ten. Routine SETPULL attempted to make a pulldown window with no selections in same. This consecutive "***"'s may be in the data stream. 108 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. The number of choices in a call to CHOICEWIND or CHOICEBAR must equal one to ten. ERROR 15 The minimum size of a scroll window when routine SCRLWIND is called not wide enough or does not contain enough rows. The size varies if < OK > and < CANCEL > buttons are used. See the descrip- tion for routine SCRLWIND for details. ERROR 16 At least one of the strings in the list for a scroll window ( SCRLWIND ) will not fit in the window, allowing for a space on either side of the string. ( non-virtual scroll windows only ) ERROR 21 The screen number specified in a call to SETINPT, MAKEFIELD, or MULTINPT does not equal one to 10. The screen number specified in a call to MULTINPT or MAKEFIELD has not been defined by a previous call to SETINPT. MULTINPT has been called with no fields previously defined by MAKEFIELD. ERROR 22 A bad field number has been specified. Routine MAKEFIELD may use field numbers one to 150. The field, however, must not be greater than the highest previously defined field number plus one. The TOFLD% argument in a call to MULTINPT is attempting to access a field which does not exist for the specified MULTI-FIELD input screen The FROMFLD% argument in a call to MULTINPT does not equal zero or a valid field number for the specified MULTI-FIELD input screen. ERROR 23 The color of a field in a call to INPTWIND or MAKEFIELD equals zero. This includes the field's inactive color, active color, or mouse active color in a call to MAKEFIELD. 109 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved. ERROR 24 The field code in INPTWIND does not consist of legal characters. ("0","1","2","3","4","5","6", "A","L","U","D","P0","P1","P2","P3","P4","P5, "P6, "R" or "RP" ) The field code in a call to MAKEFIELD is illegal. SEE THE FIELD CODE CHART IN THE APPENDIX. ERROR 25 The requested width of in input field in INPTWIND or MAKEFIELD is out of range. The maximum width is 15 for numeric fields. The minimum width for a numeric field, 0 to 6 decimal places, is the number decimal places plus one. The width for a date field must be eight or ten. The minimum width for a alpha- numeric field is one. The maximum width is 79. The maximum width for windowed fields in routine INPTWIND depends on the windows location, and the use of buttons. ERROR 26 The left column position plus the width of a field defined in a call to MAKEFIELD will not allow the field to fit on the screen. The row or column position is less than one. The row position of a field is greater than the display length specified by the previous call to SETINPT. ERROR 27 The number of characters in a restrict string for an individual field defined in a call to MAKEFIELD is greater than 255. ERROR 28 The cumulative total of restrict characters for all fields for a multi-field input screen defined via MAKEFIELD is greater than 1023. ERROR 29 The screen length when MULTINPT was called was not the same as specified when the multi-field input screen was defined by SETINPT. The screen length specified in a call to SETINPT was not 25, 43, or 50. ERROR 30 All fields defined by MAKEFIELD are protected fields. No input is possible. This error is detected when MULTINPT is called. 110 Copyright(c) 1988-92 - By: CONNECT Software - All rights reserved.
