Differences between the QuickBasic ( 4.00, 4.00b and 4.50 ) and the BASIC 7.+ (PDS) versions are detailed. The documentation can be used for the unenhanced versions with the following exceptions. 1. MULTI-FIELD INPUT SCREENS - A maximum of 2 input screens with a maximum of 25 fields per screen are available in the unenhanced version. This compares to 10 multi-field screens with up to 100 fields each, in the enhanced version. 2. MEMORY - The code in the unenhanced libraries is not modular. Therefore executable programs made with the unen- hanced libraries will contain all of the code even though all of the procedures are not used. This will substantially increase the length of any executable file and program. With the enhanced versions of WINDOWS R-E-Z, it is not necessary to link modules to executable programs if routines in a module are not used by the program. Much smaller ex- ecutable programs are consequently possible. An additional library is included in the enhanced versions which does not contain error checking or window status capability. This library can be used after the program is de-bugged and also represents an opportunity for considerable memory reduction. 3. The BASIC 7.0/7.1 unenhanced version does not allow the use of unnamed ( blank ) COMMON blocks. The enhanced version has provisions for the use of same. 4. The section labeled "MAKING A CUSTOMIZED LIBRARY" refers to the enhanced version of WINDOWS R-E-Z. ********************************************************** ** For information on obtaining the enhanced version ** ** of WINDOWS R-E-Z see the file ORDER.ME. ** ********************************************************** 1 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. Important notes for BASIC 7.0/7.1 ( PDS ) users. ENHANCED AND UNENHANCED VERSIONS: The /Ea option may be used when loading QBX. 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 column 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. ENHANCED VERSION ONLY: An additional object file PDSMEM70/71.OBJ is included which allows the use of unnamed (blank) COMMON blocks. It must re- place the object file PDSMEM.OBJ which is included in the libraries. Window memory will share main module string space after this change is made. To make this change; 1. Make new library files. ( Save old library files! ) LIB PDSALL70.LIB-PDSMEM.OBJ+PDSMEM70.OBJ; ( BASIC 7.0 ) LIB PDSNER70.LIB-PDSMEM.OBJ+PDSMEM70.OBJ; ( BASIC 7.0 ) LIB PDSALL71.LIB-PDSMEM.OBJ+PDSMEM71.OBJ; ( BASIC 7.1 ) LIB PDSNER71.LIB-PDSMEM.OBJ+PDSMEM71.OBJ; ( BASIC 7.1 ) 2. Make new quick-libraries. ( Save old quick-libraries! ) LINK/Q PDSALL70.LIB,PDSALL70.QLB,,QBXQLB.LIB; ( BASIC 7.0 ) LINK/Q PDSNER70.LIB,PDSNER70.QLB,,QBXQLB.LIB; ( BASIC 7.0 ) LINK/Q PDSALL71.LIB,PDSALL71.QLB,,QBXQLB.LIB; ( BASIC 7.1 ) LINK/Q PDSNER71.LIB,PDSNER71.QLB,,QBXQLB.LIB; ( BASIC 7.1 ) 2 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. UNENHANCED VERSION ONLY: The library in the unenhanced, BASIC 7.0/7.1, version of WINDOWS R-E-Z was made using BASIC 7.1. If you are using BASIC 7.0 the following message will appear when making executable programs from within the QBX environment. LINK WARNING L4051: BRT71EFR.LIB: CANNOT FIND LIBRARY Enter new file spec: Press ENTER. The file, BRT71EFR.LIB, is not required. The enhanced version of WINDOWS R-E-Z has libraries avail- able for BASIC 7.0 and BASIC 7.1. 3 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. *** GENERAL OVERVIEW *** WINDOWS R-E-Z is a collection of QuickBASIC and assembly routines which provide users of QuickBASIC ver. 4.00+ and BASIC 7.0+ ( PDS ) with a complete window management system. 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" and "MULTI-FIELD INPUT" routines are also provided. "INPUT WINDOWS" provide a convenient means to prompt for, and receive an input. "MULTI-FIELD INPUT" allows users to define up to 10 input screens, each having up to 100 input fields. 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. Several other routines are included which allow the use of "GET ANSWER WINDOWS" and "SCROLL WINDOWS". The ability to read KEYBOARD and MOUSE input is also provided with WINDOWS R-E-Z. 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". SAVEWIND ------- Saves a screen area to window memory. RESAVE --------- Saves the active window. 4 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. RSTRWIND ------- Restores a window area to the display. DELWIND -------- Deletes a window area from window memory. CHNGWIND ------- Changes the active window to another window. NEWCOLOR ------- Changes the print-to color of the active window for text printed by PRINTW. The print-to color is used by CLRWIND to clear the active window's interior. CLRWIND -------- Clears the interior of the active window. PRINTW --------- Prints text in the active window using the window's "print-to" color. LINEW ---------- Prints a line in the active window using the window's "print-to" color. SCRLWIND ------- Places a scrollable list in the active window. MARKED% -------- (FUNCTION) Returns position of marked items after a call to SCRLWIND. WINDSTATUS ----- Reports window memory status. SETPULL -------- Set up routine for pulldown windows. PULLDOWN ------- Makes pulldown windows. CHNGPULL ------- Changes the color of, and disables or enables an item in a pulldown window. INPTWIND ------- Makes an input field with an optional window. The field can be edited by the user. SETINPT -------- Set up routine for multi-field input screens. MULTINPT ------- Places input fields on the screen as defined by a previous call to SETINPT. GETANS --------- Makes a get answer window or single line prompt. Waits for a single key response. DOSOUND -------- Produces sound determined by SETWIND. 5 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. GETDISK -------- Returns the default disk drive. SETDISK -------- Sets the default disk drive. FINDPATH ------- Returns the default path for any drive ( current directory ). DISKSIZE ------- Returns disk size and free space. FINDDIR -------- Returns the directory of any drive or path in a string array. KEYMOUSE% ------ (FUNCTION) Waits for keyboard or mouse input, or mouse movement. Returns a code for the key pressed or mouse movement. MBUTTONS ------- Redefines the mouse buttons. MOUSEON -------- Turns the mouse on, off, or disables movement detection. -------------------------------------------------------- *** SYSTEM AND PROGRAMMING REQUIREMENTS *** COMPUTER: IBM PC (XT or AT) or compatible computer. One disk drive. VIDEO ADAPTER CARD: MONO, CGA, EGA or VGA emulating CGA. PROGRAMMING LANGUAGE: For the QB4.+ version; QuickBASIC version 4.00 or greater. - Text mode For the BASIC 7.+ (PDS) version; BASIC 7.0 or greater. - Text mode - Requires use of "far strings". This is the default if executable programs are produced from within QBX. If modules are compiled using BC on the command line ( outside of the QBX environment ) the /Fs option must be used. DOS: Version 2.1 or higher. ------------------------------------------------------- 6 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. USING WINDOWS R-E-Z THE ACTIVE WINDOW When a window is defined ( made ) the number assiged 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. 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. 1.00 SETWIND (FAST%, SND%, SHAD%, NOHIFLAG%, ISDOT%, ISARROW%) Description: SETWIND must be called at least once in any program using the routines in WINDOWS-R-E-Z, prior to calling any windowing routines. This procedure init- ializes window memory. It also sets the default window- ing speed, sound, and window shadow color. In addition it determines how the pulldown window and scroll window routines display high intensity characters and the direction arrow. 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. Arguments: FAST% is used to allow "fast" windowing if a CGA video card, or emulation, is detected. IF FAST% = 0 window routines will be slower on computers with CGA. If FAST% = 1 the window routines will be "fast" on computers with CGA. This may, however, cause "snow" with certain CGA cards. If a monochrome card is detected all windowing is "fast" and FAST% has no effect. 7 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. SND% determines which sound will be generated by the routines. If SND% = 1 a "CLICK" sound will be generated. If SND% = 2 will 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 display while setting SHAD% to 8 works well for color displays. NOHIFLAG% tells the pulldown and scroll window routines how to display high intensity "key" characters. If NOHIFLAG% = 0 and the key character's color is set to a high intensity it is displayed as high intensity. If NOHIFLAG% = 1 high intensity "key" characters are displayed in reverse video. This is appropriate for LCD displays which can not display high intensity characters. NOHIFLAG% affects "key" char- acters only. See PULLDOWN and SCRLWIND descriptions. ISDOT% sets a period or comma for the decimal designator. If ISDOT% = 1 the decimal designator is a period. If ISDOT% <> 1 the decimal designator is a comma. This is appropriate for some foreign users. ISARROW% tells the pulldown and scroll window routines to display or not display the direction arrow on the right side of the windows. If ISARROW% = 1 the arrow will be displayed. If ISARROW% = 0 the arrow will not be displayed. NOTE: If a CLEAR statement is executed by the program all window memory is lost. Any window areas saved in window memory are lost. SETWIND must be called again to re-initialize window memory after executing a CLEAR statement. ------------------------------------------------------------ Examples of a call to SETWIND. Use the first example if SETWIND will be called only once in the program. Use the second example if SETWIND may be called several times in the program. In example two the call to SETWIND is placed in a sub-routine. This is more memory efficient than calling SETWIND several times in the program. ------------------------------------------------------------ Example one: This is the easier method but the ability to change parameters based on the user's requirements is inhibited. 8 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. This call sets windowing and print speed to fast, sound to click, window shadow color to 7, no hi-intensity to no, decimal deignator to a period, and scroll bar direction arrow to on. CALL SETWIND(1, 1, 7, 0, 1, 1) ------------------------------------------------------------ Example two: This method provides the ability to easily change the parameters. In this example the sound starts out as a "click" but is changed to a "beep" by the program FAST% = 1: SND% = 1: SHADCOL% = 7 NOHIFLAG% = 0: ISDOT% = 1: ISARROW% = 1 GOSUB SETITUP ' Initial call to SETWIND 'program 'program 'Now turn the sound to "beep". SND% = 2 GOSUB SETITUP ' 2nd call to SETWIND 'program 'program CALL DOSOUND END SETITUP: CALL SETWIND(FAST%,SND%,SHADCOL%,NOHIFLAG%,ISDOT%,ISARROW%) RETURN ------------------------------------------------------------- 1.01 MAKEWIND (W%, LABEL$, TR%, LC%, WIDE%, NR%, ATTR%, BORBER%) Description: Makes a window. May also save a window- ed area to window memory. The window becomes the active window. Calls to PRINTW, LINEW, SCRLWIND, CLRWIND, RESAVE, and NEWCOLOR refer to the active window. Arguments: W% is the window number and must equal 0 to 20. If W% = 0 the area under the window is not saved. A window is simply made. If W% is from 1 to 20 the area 9 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. under the window is saved and may be restored at a later time via a call to RSTRWIND. If W% is the number of a window area previously saved by MAKEWIND or SAVEWIND an error is reported. LABEL$ 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 left 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. TR% can range from 1 to 23 or may equal 100. Any other value for TR% will result in a error. LC% is the left column position of the win- dow. If LC% = 100 the window will be centered from left to right. LC% can range from 1 to 78 if the display width is 80 or from 1 to 38 if the display width is 40. WIDE% is the window's width. WIDE% must be greater than 2. WIDE% + LC% -1 must not be greater than the displays width ( 40 or 80 ). NR% is the number of rows in the window and must be greater than 2. NR% + TR% must not be greater than 26. If NR% is less than 5 a window title box is not permitted. ATTR% is the windows colors and may be in the range of 0 to 255. The foreground ( window's label and border ) color equals ATTR% MOD 16. The background 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 10 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 has 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". 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. 11 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 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. 1.05 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 12 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. the active window's interior, RSAVE 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. 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. Additional windows may also be printed in the window. Use window number 0 to make the additional windows, as the screen area under them need not be saved. 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. 1.06 RSTRWIND (W%, DELFLAG%) Description: Restores a window area previously saved by MAKEWIND, SAVEWIND or RESAVE. The window area (W%) must exist in window memory or RSTRWIND does nothing. 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. 13 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 1.07 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. Argument: W% is the window area number. 1.08 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 1.09 NEWCOLOR ( ATTR% ) Description: Changes the print-to color of the active window. Text printed in the window by PRINTW or lines printed in the window by LINEW 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. 1.10 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 14 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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. 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 THE LINE IN THE WINDOW, POSITIONED IN ROW, ROW% WILL BE ERASED. 1.11 WINDSTATUS Description: This is a programming tool. Calling WINDSTATUS reports each window'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 desireable to view each windows parameters. The program will terminate and must be restarted. First remove the call to WINDSTATUS. Arguments: None. 15 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. ***** PULLDOWN WINDOWS ***** These procedures generate a maximum of 10 pulldown windows with a maximum of 20 items ( lines ) in each window. The area covered by the pulldown windows is saved and restored as the window moves from one menubar item to the next. Unlike the other windowing procedures pulldown windows will only work in the 80 column display width mode. 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 CHAR- ACTER" 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 key always exits. 2.00 SETPULL (BAR$, PWIND$()) Description: Must be called to set up the routine PULLDOWN. Call SETPULL only once at the beginning of each program using pulldown windows. Arguments: BAR$ is the menubar. If BAR$ = "THIS IS A SAMPLE" the menubar is; THIS IS A SAMPLE. Two spaces are placed between each menubar item ( THIS, IS, A, SAMPLE ). The maximum length of the menubar is 80 characters including the spaces. No more than 10 menubar items are permitted. Error detection checks for the menubar length and number of items. PWIND$() is an array that contains all of the strings representing the items in each pulldown window. PWIND$() must be in the correct format. ( SEE: EXAMPLE OF A CALL TO SETPULL ). The last item 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). Each selectable item in PWIND$() has a "KEY CHARACTER". The key character is the character which is searched for when a key is pressed while in the PULLDOWN enviornment. The key character defaults to the first character in each item. To designate the key character as a different character follow the character with a "@". EXAMPLE: PWIND$(1) = "Get File" ( Key character = "G") PWIND$(2) = "Save F@ile" ( Key character = "F") 16 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. The "@" will not be displayed when the string is printed in the pulldown window. The description for KEYATTR% for the routine PULLDOWN describes how to make the key character a different color, or high intensity, enabling users to distinguish it as the key character. NOTE: DO NOT PLACE THE "@" IN POSITION ONE OR TWO OF THE STRING AS IT WILL PRINT IN THE PULLDOWN WINDOW. AS STATED THE KEY CHARACTER WILL DEFAULT TO POSITION ONE IF THE "@" IS OMITTED FROM THE STRING. THIS ELIMINATES THE NEED TO PLACE THE "@" IN POSITION TWO. If an element of PWIND$() = "-" 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$(3) = "-" Providing PWIND$(3) is not last item in the pulldown window PWIND$(3) will print as a line across the window. -------------------------------------------------------- EXAMPLE OF A CALL TO SETPULL BAR$ = "THIS IS A SAMPLE" 'MENUBAR STRING DEFINED.

First the menubar is defined, then an array is dimen- sioned to hold the pulldown window's data. 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". The last menubar item is "SAMPLE" and it's pulldown window contains one item "BYE". 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 (MENUBAR%, WINDITEM%, ATTR%, KEYATTR%, BORDER%) Description: Places the menubar on line one. Places the user in the pulldown window environment. Arguments: MENUBAR% is the sequential number ( left to right ) of selected menubar item . It is returned to the calling procedure (PULLDOWN). If the second item in the menubar is selected, MENUBAR% will equal two. If the ESC key is pressed MENUBAR% = 0. WINDITEM% represents the row number of the selected pulldown window item. It is returned to the calling procedure. If the ESC key is pressed WINDITEM% = 0. NOTE: A LINE IN A PULLDOWN WINDOW OCCUPIES A ROW POSITION. 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 each item in the pulldown windows. If KEYATTR% = 0 the key character will be the same color as the other characters in each window item. This would be appropriate if the first charcter in each item is ALWAYS the key character. Setting KEYATTR% to a 18 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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. BORDER% is the pulldown window's border designation. BORDER% can be 0,1,2,10,11 or 12 for pulldown windows. Any other value for BORDER% will result in an error. SEE THE BORDER DESIGNATION CHART. 2.02 CHNGPULL ( BARITEM%, WINDITEM%, ATTR% ) Description: Changes the color of an item in a pulldown window. Also disables or enables the ability to select the item. 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. 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. 19 Copyright (c) 1988 - 1991 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. Pressing the ENTER key 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. SCRLWIND searches from the position of the scroll bar to the last item in the window ( list ) to see if the key pressed is the KEY CHARACTER of any element of the list. If a match is found the scroll bar moves to that position in the list. 3.00 SCRLWIND (LIST$(), ENTRIES%, KIND$, RTRN%, KEYATTR%) Description: Places a list ( LIST$() ) in the active window. The list is ENTRIES% long. Arguments: LIST$() 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 an error is reported. LIST$(1) must be the first string in the array, NOT LIST$(0). Each selectable item in LIST$() has a "KEY CHARACTER". The key character is the character which is searched for when a key is pressed while in the SCRLWIND enviornment. The key character defaults to the first character in each item. To designate the key character as a different character follow the character with a "@" in the string. EXAMPLE: LIST$(1) = "Get File" ( Key character = "G") LIST$(2) = "Save F@ile"( Key character = "F") The "@" will not be displayed when the string is printed in the scroll window. The description for KEYATTR% for this routine describes how to make the key character a different color, or high intensity, enabling users to distinguish it as the key character. NOTE: DO NOT PLACE THE "@" IN POSITION ONE OR TWO OF THE STRING AS IT WILL PRINT IN THE SCROLL WINDOW. AS STATED THE KEY CHARACTER WILL DEFAULT TO POSITION ONE IF THE "@" IS OMITTED FROM THE STRING. THIS ELIMINATES THE NEED TO PLACE THE "@" IN POSITION TWO. 20 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. If an element of LIST$() = "-" 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$(2) will print as a line.) ENTRIES% is the number of elements in the array ( LIST$() ) to use in the scroll window . KIND$ is as follows; IF KIND$ = "A" when entering SCRLWIND the scroll window is an "AUTO-EXIT" scroll window. If the key pressed equals the key character of an item in the scroll window and the item is between the scroll bar and the end of the list the routine will automatically exit. The position of the selected item in LIST$() will be returned in RTRN%. If RTRN% = 2, LIST$(2) was selected. IF KIND$ ="M" when entering SCRLWIND the scroll window is a "MARK" scroll window. Pressing the <+> or INSERT key marks the item covered by the scroll bar. A right arrow is printed to the left of the item in the scroll window to signify it has been marked. Pressing the <-> or DELETE key un-marks an item if it was marked. Striking the PRINT key or space bar marks all items, unless they were all previously marked, in which case the PRINT key or space bar will unmark 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$(26), LIST$(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$(26) ) in KIND$. See the description for the function MARKED% for a method of decoding KIND$. IF KIND$ = "S" when entering SCRLWIND the scroll window is a "SINGLE MARK" scroll window. Provided there is more 21 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. than one item ( ENTRIES% > 1 ) in the scroll window, one item will be marked as in the preceding example for a "MARK" scroll window. Only one item can be marked, however. The marked item follows the scroll bar. Pressing TAB, ENTER, RETURN or ECS will exit the scroll window. If TAB, ENTER or RETURN is pressed the selected item number is returned in RTRN%. If the scroll bar is over LIST$(2), RTRN% = 2. If ESC is pressed RTRN% = 0. SINGLE MARK scroll windows with one entry ( ENTRIES%=1 ) do not mark the item. RTRN% = 1 if ENTER or RETURN is pressed. RTRN% = 0 if ESC is pressed and RTRN% = -1 if TAB is pressed. These scroll windows can be used as <OK>, <CANCEL>, <ABORT> etc... scroll windows. NOTE: SEE THE SECTION LABELED "Multiple Scroll Windows" TO SEE HOW SINGLE MARK SCROLL WINDOWS CAN BE USED TO DISPLAY AND USE SEVERAL SCROLL WINDOWS AT ONE TIME. IF KIND$ = "V" the scroll window is "VIEW ONLY". 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. The window will be filled with the strings in LIST$(). If ENTRIES% > 1 the item designated by the value of RTRN% will be marked. ( See description for RTRN%. ) Any other value for KIND$ 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%. RTRN% serves two purposes. One is to place the scroll bar over a the item specified by RTRN% when entering SCRLWIND. If RTRN% < 1 or RTRN% > ENTRIES%, 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. IF ECS is pressed to exit SCRLWIND, RTRN% = 0. If TAB is pressed and the scroll window is a "SINGLE MARK" scroll window with over one entry, RTRN% returns the selected item. If the scroll window is a "SINGLE MARK" scroll window with one entry and TAB is pressed, RTRN% = -1. 22 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. NOTE: THE ITEM SELECTED IN LIST$() ( AS INDICTED BY THE VALUE OF RTRN% ) MAY CONTAIN A "@" TO INDICATE THE KEY CHARACTER. IF IT IS NESESSARY TO PRINT THE ITEM THE "@" CAN BE REMOVED FROM IT USING THE FOLLOWING FUNCTION. ' FUNCTIONS MUST BE DECLARED. RTRN% = ITEM # SELECTED ' FROM LIST$(). 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 "@" IN ITEM$. ELSE NO$ = LEFT$(ITEM$, A% - 1) + MID$(ITEM$, A% + 1) END IF END FUNCTION 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 charcter in each item is ALWAYS the key character. Setting KEYATTR% to a different color, or high intensity, allows users to distinguish the character as the 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. ------------------------------------------------------- 'EXAMPLE OF A CALL TO SCRLWIND - AUTO EXIT SCROLL WINDOW DIM LIST$(11) FOR X% = 1 TO 11 'ALWAYS START WITH 1 READ LIST$(X%) NEXT 23 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved.

Arguments: RTRN$ is the string returned by calling SCRLWIND with the MARKED option ON. RTRN$ = "" if no items were marked. START% is the postion in RTRN$ to start searching for a CHR$(26). A CHR$(26) in RTRN$ represents a marked element in the string array LIST$() used in SCRLWIND. Every time a position in RTRN$ is found which corresponds to a marked element of LIST$(), START% is set to a new value which is equal to the "marked" position in RTRN$ + 1.

The prompt may, optionally, be windowed. The key may be any key, or individual keys from a list of permissible keys. The area covered by the get answer window is restored after the key is pressed. 4.00 GETANS (PROMPT$, CHOICE$, ANS$, TR%, LC%, ATTR%, BORDER%) Description: Generates a prompt with an optional window and pauses, waiting for a reply. Arguments: PROMPT$ 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" or "y" or "N" or "n" keys will exit GETANS. The ESC key will always exit regardless of CHOICE$. ANS$ is 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 ATTR% is the color designation. See MAKEWIND. Although it is permissible to set ATTR% > 127 to make the border flash the text will not flash. 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: CALL GETANS ("Are you sure? Y/N", "YN", ANS$, 100, 100, 240, 11) ( Above must be on one line. ) 29 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. A window will be generated with the text "Are you sure? Y/N" printed in it. With TR% and LC% set to 100 the window will be centered on the screen ( See MAKEWIND ). ATTR% = 240, therefore, the window will be white with black text and a black flashing border. The user may press the N, n, Y, y, or ESC keys to exit. The key pressed will be returned to GETANS in the argument ANS$. 30 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. ***** INPUT ROUTINES ***** Input routines provide users with the ability to generate 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 100 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 zero's. Numerous additional options are available. 5.00 INPTWIND (PROMPT$,CODE$,TR%,LC%,WD%,ATTR%,RES$,RTRN$,BORDER%) Description: Makes an input field, which may optionally be windowed. The area under the field or window is auto- matically saved. It is restored upon exiting the routine. Arguments: PROMPT$ is the message which will be printed to the left of the input field or in the title box of the window, if one is specified. If PROMPT$ is preceded by a "@" it will be centered in the title box. CODE$ sets the type of input field and may may equal the following: "A" - Alpha/numeric. All standard keys are active. "U" - Alpha/numeric. Upper case. "L" - Alpha/numeric. Lower case. "D" - Date. If a field is a date field it can not be exited unless the date is valid or the field is blank. The number keys, "/" and "-" are active. Valid dates range from 1/1/1980 to 12/31/2099. "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 are "P3" or "3" entered. The field can not be exited "P4" or "4" unless the number, with the correct "P5" or "5" number of decimal places will fit in the "P6" or "6" the field. or the field is blank. The numeric,"-", and "." keys are active. 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. 31 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 dec- imal point and padded with leading zeros. TR% is the top row of the field, or window. If a window is designated, TR% must equal 1 to 23. Without a window TR% must equal 1 to 25. Setting TR% to 100 centers the field, or window, top to bottom. LC% is the left column. If a window is designated, LC% must equal 1 to 76 ( 36 in 40 column mode ). With no window LC% must equal 1 to 79 ( 39 in 40 column mode ). If LC% = 100 the field, or window, is centered left to right. If LC% is set so the input field 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 fields 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, and for an alpha/numeric field WD% can range from 1 to the screen width minus 1 ( minus 4 if windowed ). ATTR% is the window's and PROMPT$'s color. The color of the input field is the inverse of the window's color. The field's foreground color is the same as the window's background color while the field's background has the same color as the windows foreground. SEE THE COLOR ATTRIBUTE CAHRT. To make the field's foreground color high intensity, add 1000 to ATTR%. EXAMPLE: ATTR% = 1160. ( 1000 + 160 ) The "160" produces a flashing black on green window. ( SEE THE COLOR ATTRIBUTE CHART. ). The "1000" makes the field text high intensity green. RES$ is the restrict string. It holds the allowable characters which can be entered in the input field. RES$ IS IGNORED IF CODE$ IS NOT ALPHA/NUMERIC ("A"). IF CODE$ IS ALPHA/NUMERIC ("A") AND RES$ = "" ALL STANDARD ALPHA/NUMERIC KEYS ARE ALLOWABLE. (SEE SETINPT IN SECTION 5.01 FOR DETAILS.) 32 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 BORDER% is the input windows border. ( SEE THE BORDER DESIGNATION CHART ). If BORDER% = 0 a single line input field ( no window ) is generated. If BORDER% produces a title box window, PROMPT$ will printed in the title box. 5.01 SETINPT ( SCRN%, COLWID%, EXIT$, INPT%(), INPT$(), ACTCOL% ) Description: Defines a multi-field input screen, which will be called by MULTINPT. Arguments: SCRN% is the number or the screen being defined. SCRN% may range from 1 to 10. COLWID% is the column width of the screen and must equal 40 or 80. EXIT$ is the code for keys which will exit the multi-field input routine for the designated screen number. To make the function keys active place their number "1","2" etc in EXIT$. A "0" represents the F10 key, a "D" the PGDN key and a "U" the PGUP key. EXAMPLE: IF EXIT$ ="03U" THE F10, F3, OR PGUP KEYS WILL EXIT THE MULTI-FIELD INPUT ROUTINE ( MULTINPT ). INPT%() and INPT$() hold the data representing the parameters for each field in the multi- field input screen. Starting at INPT%(1) and INPT$(1), INPT%() AND INPT$() are as follows; ------------ INPT%() ---------- -INPT$()- 1 2 3 4 5 6 1 (Field #1) CODE%, TR%, LC%, WD%, ATTR%, 99, RES$ (Field #2) ...... Repeat above for each field 9999 ( signals end of INPT%()/INPT$() ) INPT%(1)=CODE% FOR FIELD 1, INPT%(7)=CODE% FOR FIELD 2 INPT$(1)=RES$ FOR FIELD 2, INPT$(2)=RES$ FOR FIELD 2 33 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. CODE% is the code for type of input field and can be as follows; 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. 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) 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 always" field. The multi-field input routine will be exited whenever the cursor is moved from an "Auto-exit always" field. Adding 20000 to CODE% makes the field an "Auto-exit on change" field. The multi-field input routine will be exited only when the data in the field is changed and the cursor is moved from the field. This is useful if a field is part of a formula to calculate another fields value. Adding 30000 to CODE% makes the field a "Fixed choice" field. A fixed choice field will exit the multi-field input routine if the space bar is pressed or if the cursor is moved from the field. This makes the field an auto-exit (always) field. The description for the procedure MULTINPT describes the details of a "fixed choice" field. EXAMPLE: If CODE%= 21017 THEN CODE% = 20000+1000+17. THE FIELD IS ALPHA/NUMERIC ( UPPER CASE ), AUTO-ADVANCE AND "AUTO-EXIT ON CHANGE". ** SEE THE MULTI-FIELD CODE CHART IN THE APPENDIX.** 34 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. TR%, LC%, and WD% are the same as in INPTWIND. ATTR% is the fields color. 99 is a check and must follow the numeric data which defines each field. 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. ACTCOL% is the color attribute of the active input field. Use ACTCOL% to make the active field a different color than the inactive fields. If ACTCOL% = 0, ACTCOL% is ignored and the active field's color will not change. ACTCOL% is adjusted to ACTCOL% MOD 128. ------------------------------------------------------- 'EXAMPLE OF A CALL TO SETINPT A% = 20: B% = 3 ' SET UP TEMPORARY ARRAYS FOR DATA.

'------------------------------------------------------- 5.02 MULTINPT ( SCRN%, FLD%, EXIT$, AUTOEXIT%, RTRN$() ) 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. FLD% serves two purposes. When entering MULTINPT, FLD% 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. 36 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. When exiting MULTINPT, FLD% points to the next field the cursor would normally occupy. If a field is auto-exit ( always ) and the down arrow is pressed, MULTINPT will be exited. FLD% 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, FLD% will point to the fixed choice field ( the one the cursor was in before MULTINPT was exited ). EXIT$ also serves two purposes. When entering MULTINPT, setting EXIT$ to "VIEW" causes MULTINPT to print and fill the fields with their corresponding data. MULTINPT is then exited. This is useful for viewing a multi-field screen or updating a single field ( see AUTOEXIT% ). Any other value for EXIT$, allows MULTINPT to act normally. The field or fields are filled and the program requires user input. When exiting MULTINPT, EXIT$ will equal "F1" to "F10", "PGUP" or "PGDN" if a valid exit key was pressed. Valid exit keys are determined via the call to SETINPT for the multi-field input screen. EXIT$ will equal "AUTO" when MULTINPT is exited, if it was exited by an auto-exit field. EXIT$ will equal "FIXED" if MULTINPT is exited when the space bar is pressed and the cursor is in a fixed choice field. It is important to note that fixed choice fields are also auto-exit ( always ) fields. If a fixed choice field is exited via the cursor moving from it to another field EXIT$ will equal "AUTO". NOTE: EXIT$ IS CASE SENSITIVE. AUTOEXIT% also serves two purposes. If AUTOEXIT% is set to zero, MULTINPT, when entered, will update all fields. If AUTOEXIT% 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. When MULTINPT is exited AUTOEXIT% is set to zero or to an auto-exit field number. The value of AUTOEXIT% remains the same if MULTINPT is exited by an exit key (F1,F2..) or by an auto-exit or fixed choice field. The following conditions will set AUTOEXIT% to a field number ( not zero ). 1. The cursor was in an auto-exit field ( always ) field and MULTIPT was exited by an exit key or the auto-exit feature ( cursor moving from the field ). 37 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 2. The cursor was in an autoexit ( on change ) field, the field's data was changed, and MUTINPT was exited by an exit key or the auto-exit feature. 3. The cursor was in a fixed choice field and MULTINPT was exited by an exit key, by the space bar being pressed, or by moving the cursor from the fixed choice field. As previously stated fixed choice fields are also autoexit ( always ) fields. NOTE: If the cursor is in an auto-exit or fixed choice field and MULTINPT is exited via an exit key (F1,F2..) EXIT$ will not equal "AUTO". It will equal the key pressed ( F1,F2 .. etc. ). Check AUTOEXIT% to verify if the cursor was in an auto-exit field when MULTINPT was exited. If AUTOEXIT% equals a valid field number ( not zero) and EXIT$ = "VIEW" when entering MULTINPT, the field specified by the value of AUTOEXIT% will be updated and MULTINPT will be exited. This method can be used to update any single field and exit. 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) When MULTINPT is exited RTRN$() holds the data in it's edited state. Upon entering MULTINPT, if the field is designated as alpha/numeric and the string will not fit in the field it will be truncated to fit. If the field is numeric and a number formatted to the correct number of decimal places will not fit in the field, "*"'s will be printed. This will not pose a problem if RTRN$() 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! 38 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 ) REM: SET TO "9999999999999999" AND "*"'s WILL REM :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" 39 Copyright (c) 1988 - 1991 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."

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. 6.00 GETDISK (DRIVE%) Description: Retrieves the default disk drive. Argument: DRIVE% is the current drive. DRIVE% = 1 for drive A:, 2 for B:, 3 for C:, 4 for D:, etc. 6.01 FINDPATH (PATH$) NOTE: ALWAYS TRAP FOR DISK ERRORS PRIOR TO CALLING THIS ROUTINE. SEE SECTION " MAKING A DIRECTORY SCROLL WINDOW" Description: Retrieves the current path ( directory ). Argument: PATH$ is the path in the format: DRIVE:\SUB-DIRECTORY\SUB-DIRECTORY\.... PATH$ always starts with the drive letter and always ends with a "\". 6.02 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 41 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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. 6.03 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. 6.04 FINDDIR (PATH$, TYP$, FILE%) NOTE # 1: THE FOLLOWING MUST BE PLACED BEFORE ANY EXECUTABLE STATEMENTS IN ANY MODULE CALLING "FINDIR" 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. 42 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 FIND FILES IN DRIVE C:, SUB-DIRECTORY "TEST", WITH THE EXTENSION ".BAS". TYP$ designates the attributes of the files to include in the search. 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 - archived files 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$(). A long directory search places the file's size, date, time and attrtibute designation in DIRINFO(). DIREC$(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 volumn entry. IF DIRINFO(1).ATTR AND 16 the entry is a sub-directory. 43 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 SEARCH IS LONG.

NOTE: THESE 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". 7.00 KEYMOUSE% Description: KEYMOUSE% is a function. It pauses program execution. Upon keyboard or mouse input the program resumes with the appropriate code returned in KEYMOUSE%. The mouse buttons are user defineable via the procedure MBUTTONS. Mouse movement emulates the arrow keys. Up, down, left, and right mouse movement places the same value in KEYMOUSE% as the corresponding arrow key. If the key or mouse button pressed produces a standard ASCII/IBM character, the code for the character ( 1 to 255 ) is returned in KEYMOUSE%. If the key pressed, or mouse movement, produces an extended scan code such as the up arrow, the extended scan code for the key multiplied by 256 is returned in KEYMOUSE%. KEYMOUSE% returns 18432 ( 72 * 256 ) for the up arrow. For those keys which produce an extended scan code over 127, such as CTRL-PGUP ( 129 ), KEYMOUSE% returns a negative value. SEE THE KEYMOUSE CODE CHART IN THE APPENDIX. NOTE: THIS IS AN ASSEMBLY ROUTINE.

If LBUTTON% is greater than 255 it is converted to LBUTTON% AND 255 RBUTTON% sets the value which will be returned in function KEYMOUSE% when te right mouse button is pressed. It may range from 0 to 255. If RBUTTON% is greater than 255 it is converted to LBUTTON% and 255. -------------------------------------------------------- ' EXAMPLE: SETS THE LEFT MOUSE BUTTON TO "RETURN" AND ' THE RIGHT MOUSE BUTTON TO "ESC". 13 IS THE ASCII CODE ' FOR "RETURN". 27 IS THE ASCII CODE FOR "ESC".

MAKING A CUSTOMIZED LIBRARY ( Enhanced version only ) Users familiar with LINK and LIB utilities may prefer to create libraries outside of QuickBASIC's environment using the appropriate object files. As individual assembly object files can be linked together to create smaller libraries this is the preferable method. See the section "FILES" for a description of all files. The libraries ( QB4ALL.QLB, PDSALL70.QLB, PDSALL71.QLB, QB4ALL.LIB, PDSALL70.LIB and PDSALL71.LIB ) are complete and contain all of the procedures in WINDOWS R-E-Z. If all of the procedures are not required in your program customized libraries using less memory may be made in the QuickBASIC environment as follows: For QB 4.00 and 4.00b: 1. Load QuickBASIC using the command QB/L QB4ASM. The file, QB4ASM.QLB, contains the assembly routines required by all of the other procedures. 2. Load the modules WIND_REZ.BAS and QB4MEM.BAS. ALL PROCEDURES EXCEPT THOSE IN DIRWIND.BAS REQUIRE THESE MODULES. They contain the basic windowing routines. If this is all your program requires select the Make library option from the Run menu in QuickBASIC (see your manual) to make the library. ( QB4ASM.LIB must be present.) 3. Load any other modules your program requires. IF YOU WANT TO USE PULLDOWN WINDOWS THE MODULES PULLDOWN.BAS AND SCROLL.BAS MUST BOTH BE LOADED. All other modules may be loaded independent of each other. When all of the modules you will be using are loaded make the library as in step 2. Two libraries will be produced. The library with the suffix .QLB is used in the QuickBASIC environment and the library with the suffix .LIB must be available to produce an executable file. To use your new library ( assuming a name of NEWLIB.QLB ) exit QuickBASIC and reload with the command QB/L NEWLIB. For QuickBASIC version 4.50 and BASIC 7.+ ( PDS ); Versions 4.5 of QuickBasic and BASIC 7.0+ ( PDS ) do not use the "full library" mode while linking. Therefore it is not nesessary to build a customized library or link outside of the QuickBASIC environment to produce the smallest possible executable programs. 53 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved.

Errors The following is a listing of the errors WINDOWS R-E-Z will detect. ERROR # DESCRIPTION ------------------------------------------------------------ ERROR 0 There is no active window. SCRLWIND, RESAVE CLRWIND, PRINTW, LINEW, and NEWCOLOR require an active window. ERROR 1 SETWIND has not been called to initialize window memory. This error will be reported if the program uses a CLEAR statement and SETWIND has not be called to re-initialize window memory. ERROR 2 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 minimim window number for SAVEWIND, DELWIND, and RSTRWIND. Window number 0 is the minimum window number for MAKEWIND and CHNGWIND. ERROR 3 The shadow, specified in a call to MAKEWIND, will not fit on the screen. If this error is displayed the window will fit on the screen but the shadow will not. ERROR 4 The window will not fit on the screen. 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. 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. PULLDOWN windows have a width based on the longest item in the pulldown window's list. This error is displayed 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 56 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. 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 save by MAKEWIND. ERROR 7 A call was made to RESAVE when the active window was window number 0. RESAVE can only resave active window 1 to 20. ERROR 8 An window specified in a call to MAKEWIND or SAVEWIND previouly existed. A window must be deleted via a call to DELWIND or RSTRWIND before the number assigened to it can be used again. This error will not be reported for window number 0 as it is not saved. ERROR 11 A bad row number was specified in a call to PRINTW or LINEW. The row number must be greater than 0. PRINTW allows print on the bottom border. LINEW does not. The string specified in a call to PRINTW will not fit in the window due to it's length or it's left column ( start print ) position. ERROR 21 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. ERROR 22 A call was made to SCRLWIND with less than one entry ( ENTRIES% ). ERROR 23 A scroll window requires a minimum width of 5. ERROR 24 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. ERROR 31 The menubar string specified in a call to SETPULL is missing or has the wrong format. ERROR 32 The menubar string specified in a call to SETPULL has over 10 items in it. A space between two characters is the separator for the items. 57 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. ERROR 33 The data supplied to SETPULL is in the wrong format. The end of each pulldown window must be represented by "***" in the data stream. The end for all pulldown windows must be represented by "ENDPULL". A pulldown window entry is a null string. ERROR 34 Over 20 items are requested for an individual pulldown window. This may occur if a pulldown window separator ("***") is missing. ERROR 35 There are no items in a pulldown window. Two consecutive "***"'s may be in the data stream. ERROR 36 The menubar has less than 2 items in it. There must be spaces between the items. ERROR 41 The requested width of in input field in INPTWIND is out of range. The maximum width is 15 for numeric fields, the screens width minus 4 for windowed ALPHA/NUMERIC fields or the screens width minus 1 for un-windowed ALPHA/NUMERIC fields. The minimum width for a numeric field is the number of decimal places plus one. The minimum width for an ALPHA- NUMERIC field is 1. A date field must have a width of 8 or 10. ERROR 42 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, or "P6 ) ERROR 51 The screen number in MULTINPT is less than one or over 10. ERROR 52 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 53 The screen number in a call to MULTINPT was not defined via a call to SETINPT. ERROR 54 The field number specified in call to MULTINPT is greater than the number of fields in the multi-field input screen or less than one. The auto-exit field is greater than the number of fields in the multi-field input screen or less than 0. 58 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved. ERROR 55 The screen width when MULTINPT was called was not the same as specified when the multi-field input screen was defined by SETINPT. ERROR 61 The screen number in a call to SETINPT is less than one or greater than 10. ERROR 62 The screen width in a call to SETINPT is not 80 or 40. ERROR 63 The exit string ( EXIT$ ) in a call to SETINPT is null or contains an illegal character. Legal character are: "1234567890UD". ERROR 64 The input data ( INPT%(), INPUT$() ) is not in the correct format in a call to SETWIND. ERROR 65 Over 100 fields were defined in a call to SETINPT. ERROR 66 Less than 2 fields were defined in a call to SETINPT. ERROR 67 At least one field in a call to SETINPT has an illegal field code. SEE THE MULTI-FIELD CODE CHART. ERROR 68 The field width is not appropriate for the type of field specified in a call to SETINPT. ERROR 69 The left position plus the width of a field defined in a call to SETINPT will not allow the field to fit on the screen. The row or column position is less than one. The row position of a field is greater than 26. ERROR 70 All fields defined in a call to SETINPT are protected fields. No input is possible. ERROR 71 The cumulative total of restrict characters for all fields for a multi-field input screen defined via SETINPT is greater than 1023. ERROR 72 The number of characters in a restrict string ( INPT$() ) for an individual field defined in a call to SETINPT is greater than 255. ERROR 73 The array ( INPT$() ) in SETINPT, which defines the field's restrict strings is dimensioned less than the number of fields or has a lower dimension graeter than one. 59 Copyright (c) 1988 - 1991 By:CONNECT Software All rights reserved.
