This easy-to-use software product allows you to build and maintain structure charts and data structure diagrams. You can improve your productivity by providing a sound blueprint of how program components fit together as you build your structure chart. The graphic editing available in the product makes modification easy and documentation reliable. You can decompose more complicated structure chart modules into entirely separate charts and build as simple or complex charts as are necessary. This SCdraw User Guide is designed to provide you with the necessary instructions for creating structure charts on a personal computer system. This manual is divided into twelve sections. A description of each section follows: INTRODUCTION - This section describes the intended use of the SCdraw software package. SYSTEM REQUIREMENTS - This section describes the type of personal computer system required to use the SCdraw software package. It also gives recommendations for optimal use of the package and optional output devices that can be used. SETTING CONFIGURATION - This section outlines the steps you must take to modify the SC.BAT file to match your video, printer, and plotter devices. UNDERSTANDING STRUCTURE CHARTS - This section explains the types of symbols that are supported in SCdraw and what they mean in terms of designing a chart. THE KEYBOARD - This section outlines the keys that are used by SCdraw and their associated function. FIVE MINUTE LESSON - This section focuses on how to perform particular functions immediately upon starting SCdraw. CHART MENU - This section explains the CHART menu functions - retrieving an existing chart, creating a new chart, deleting an existing chart, renaming an existing chart, creating a copy of an existing chart, listing the file names in a directory, changing the directory and changing the default drive. ADD MENU - This section explains the functions available from the ADD menu - adding modules, links, loops, diamonds, boundaries, off page connectors, text, and data/control parameters. OTHER MENU - This section explains the remaining functions available from the OTHER menu - moves, deletes, changes, duplicates, group functions, changing the chart size, highlighting, leveling, redrawing, and changing the default settings in the profile. PLOTTING/PRINTING - This section provides a brief instruction on how to print or plot a chart and the default color settings for a plotter. USING A MOUSE - This section describes usage of a mouse with SCdraw. ERROR MESSAGES - This section lists error messages, common causes and solutions for each. SYSTEM REQUIREMENTS What hardware is required? 1. Any MS-DOS PC or clone (8088, 80286, 80386, 80486, 80???). 2. At least one floppy drive or a hard disk. 3. MS-DOS or PC-DOS, Level 2.0 or higher. 4. Monitor and graphics card. The following chart lists the monitor/card configuration that SCdraw supports indicating the resolution and number of colors that are available with the identified equipment. CARD/MONITOR DISPLAY ------------ --------------------------------------------- APA or XGA 720 x 350 2 colors (IBM 3270 w/5272 monitor) CGA (Lores) 320 x 200 4 colors CGA (Hires) 640 x 200 2 colors EGA 640 x 350 4 colors (16 with extra 64K) HERCULES 720 x 348 2 colors (monochrome monitor) MCGA 640 x 480 2 colors TECMAR (color) 640 x 200 16 colors (CGA monitor) TECMAR (mono) 720 x 352 2 colors (monochrome monitor) VGA 640 x 480 16 colors 5. An 8087, 80287, or 80387 math co-processor is optional. A math co-processor will dramatically increase the speed of drawing and editing your structure charts by a factor of 4 to 6. What do we recommend? There are several configurations that will give you equally high resolution graphics. However to take advantage of this resolution plus color, we recommend the following: EGA or VGA Color Monitor and video card 80286 or 80386 PC with minimum of 320KB of RAM memory 80287 or 80387 Math Co-Processor chip. What Output devices can I use? SCdraw also supports a wide range of output devices. These include: Printers: Epson-(narrow) FX and RX Epson-(wide) FX, RX, and LQ1500 Toshiba-P321, P351, P1350, and P1351 IBM-5152 and Proprinter Star Micronics-Delta 10 and Delta 15 OKIDATA-ML92, ML93 (need plug and play) Hewlett Packard Laser Jet- Plus, 500+, Series II, and Series III Hewlett Packard Deskjet Plotters: Hewlett Packard-7220, 7470A, 7475A, 7550A, ColorPro, Draftmaster IBM-7371, 7372 Sweet Pea-Six-Shooter Pointing Devices Microsoft Mouse Mouse Systems PC Mouse SETTING CONFIGURATION SCdraw as supplied, assumes that your personal computer system is equipped with the following: CGA Color Monitor CGA Graphics card Epson FX100 Printer HP 7475A plotter If your system configuration differs, you must modify the SC.BAT file to match your configuration. How do I change SCdraw to match may configuration? You can modify the SCdraw startup file to match your system by editing the file named "SC.BAT". The SC.BAT file consists of three lines: SET NO87=Y ECHO OFF SCGO IBMCGMA1 EPSFX100 HP-7475A | | | | Pos. 1 6 15 24 Edit the SC.BAT file using an ASCII editor, as shown in the following examples. If you have a math co-processor installed, remove the line containing SET NO87=Y. Refer to Driver Tables on the following 2 pages for your options. Example 1 If your system has an EPSON FX80 printer but no plotter, change the third line of the SC.BAT file to read: SCGO IBMCGMA1 EPSFX080 Example 2 If your system has a Hewlett-Packard 7470A or 7475A plotter but no printer, change the third line of SC.BAT file to read: SCGO IBMCGMA1 HP-7470A or SCGO IBMCGMA1 HP-7475A Note: When a printer is not specified, you must insert ten blanks between "IBMCGMA1" and the plotter field. A printer and/or a plotter can be specified, even if not present, and will not cause problems unless the device is selected for printer and/or plotting. Example 3 If your system has a VGA monitor, HP LaserJet series III printer, and a HP 7475A plotter, change the third line of the SC.BAT file to read: SCGO PS2-VGA1 HPLA1-II HP-7550A Note: The HP LaserJet series II and III use the same driver (HPLA1-II).

A sample SCdraw chart has been included, displaying the symbols discussed in this section. To load the chart for viewing, follow the steps outlined in the section, CHART MENU, under the heading "Recalling an existing chart". When prompted for OLD CHART NAME, enter SAMPLE. Structure charts consist of: I. Modules - a contiguous set of program statements that can be invoked by a name. - these can include but are not limited to: . separately compiled programs . COBOL paragraphs . Fortran subroutines - represented by a rectangle and displaying: Name Label Process ID 1. Library Macro - module that has been predefined - indicates that the module has already been written and debugged and whose object and source modules are in a library - these can include but are not limited to: . Macros . reuseable copy libraries . industry or shop standard routines - represented by double bars along the sides of the rectangle. 2. Lexical Inclusion Attribute - indicates that one module is wholly contained within the Lexical boundaries of another - represented by a rectangular hat on top the module II. Link - a connector between modules - these can include but are not limited to: . COBOL PERFORMs . PL/1 DOs . FORTRAN CALL SUBROUTINES - represented by a line with an arrow at the destination III. Loop - indicates iteration - these can include but are not limited to: . COBOL PERFORM UNTILs . PL/1 DO WHILE . FORTRAN DOs - represented by a curving arrow attached to the bottom of the module. IV. Diamond - indicates decision (if statements) - represented by a diamond at the base of the module. V. Page Connector - symbol used to indicate that the chart continues on another page. - indicated by a square with a triangular shaped bottom. VI. Data - parameters identified on the chart as being significant and passed to the next module. - the arrow indicates which way the data is flowing VII. Control - parameters that indicate control. - these can include but are not limited to: . flags . indicators . status codes - represented by a dot on the end of the tail of the arrow. THE KEYBOARD SCdraw is a menu-driven system, with menu options selected via highlighting and pressing ENTER. In some cases, selecting a menu option will cause a new menu to replace the original menu. KEYS PURPOSE ------------- -------------------------------------------------------------- ESC returns to a higher menu used to end bend point selection when drawing links and boundries. CTRL + Break terminates a currently selected menu option stops the printer or plotter INS change the speed of the cursor (graphic locator) or zoom frame. INSert off - fast (move several pixels at a time) INSert on - slow (move one pixel at a time) ENTER picks a point on the chart picks highlighted function CTRL + F1 PAN moves part of the chart that is not currently visible to the screen. To use the Pan function, press the CTRL+F1 key. This function allows you to scan a chart after using the Zoom function. Using the graphic locator, select a reference point on the diagram, press ENTER. Pick second point to determine direction of pan, press ENTER. For example, if you are zoomed in on a section of the diagram and you want to view a part of the diagram which is to the left of the currently viewed area, your second point will be to the right of your first reference point, indicating that you wish to move the diagram to the right in order to view the left section. CTRL + F2 ZOOM to enlarge a portion of the diagram on the screen for clearer viewing and editing. To use the Zoom function, press the CTRL+F2 key. This function provides you with a zoom frame that is moved by using the arrow keys on the numeric keypad. The plus (+) and minus (-) keys allow you to enlarge or reduce the size of the frame. When the frame reaches the desired position and size, press the ENTER key and the framed area will be displayed in full screen size. The zoom function can be envoked multiple times without restoring to the full chart. CTRL + F3 FULL RESTORE to return to the full scale chart after you have zoomed to another level of the chart. CTRL + F4 ONE LEVEL RESTORE to return to the view that resulted from the previous zoom. CTRL + F5 PRINT (low) to print a single density copy of the chart. CTRL + F6 PRINT (high) to print a double density copy of the chart which gives clearest print but is slower than single density. FIVE MINUTE LESSON The following steps will take you through the creation of a simple structure chart. If you are going to use this lesson please be sure of the following: - you have installed or loaded SCdraw into your PC - you have edited SC.BAT to match your PC configuration - you understand the symbols used in structure charts. I. Load SCdraw Change to the drive and directory where SCdraw is installed. Then enter SC and press "RETURN" or "ENTER" to start SCdraw. The CHART menu will appear as the program is loaded.

You have a maximum of 5 lines of 15 characters each for the full label. Press ENTER. 4. Second Line Type in the second line and press enter. If you do not want any more lines, simply press enter and SCdraw will know you have no more lines. 5. Process ID Type in the ID of the process that this module came from, if applicable and press enter. This assumes that you may have a data flow diagram with a process on it that relates to this module. Press ENTER if there is no ID. The module box with the information you just supplied will now be drawn. Now follow instructions 1-5 again and draw several more modules. When you are finished with the 'Add Module Mode', press ESC to return you to the full menu. IV. Zoom In To get a more comfortable size of symbols displayed on your chart, you can zoom in to a smaller portion of the chart. Press CNTL + F2 and you will see a square frame appear on your chart. Use the + and - keys to increase or decrease the size of this zoom frame. You can move this frame around with the mouse or cursor keys to place it over a specific area and their zoom in on just that area. When you are comfortable with the area to be zoomed in and the position of the frame, press ENTER. If you need to zoom in even clearer, follow the instructions above until the zoomed area is clearly visible and large enough to work in. You can modify the chart at any zoom level. To end this zoom function, press ESC. To return to full scale, press CNTL + F3. V. Add a Link Highlight Link on menu by moving your cursor up or down and press enter. SCdraw will respond by prompting you and asking you a series of questions. 1. Source Move the cursor via the mouse or cursor control arrows to a point on the module you want to draw a link from. Press enter. 2. Bend points Move the cursor drawing an imaginary line towards the module you want to connect to. At each turn you can establish a bend point by pressing enter. When you have reached the destination, press enter for the last time to connect the link to the module. Then press ESC to end the selection process. SCdraw will respond by drawing the link the way you drew it with your cursor keys or mouse. You can continue to add more links by following instructions 1 and 2 again. When you are finished with the 'Add Link' mode, press Enter to return you to the full menu. VI. Add Data or Control DATA and CONTROL attributes work the same way. The difference on the chart will be that DATA will have an open-ended arrow and CONTROL will have a closed-ended arrow. Highlight DATA by moving your cursor up or down to DATA and press ENTER. SCdraw will respond by prompting you and asking you the following questions. 1. SELECT DATA OR CONTROL TYPE: Highlight the selection at the top left of the screen- DATA or CTRL (control), IN (top-down), or RTD (returning, bottom-up). Press ENTER. 2. PICK POINT ON LINK SYMBOL: Move the graphic locator to a point on the link to place the DATA or CTRL arrow. Press ENTER. 3. LABEL: Type in the first line of the label for the arrow. 2 lines of 15 characters each are available for the full label. Press ENTER. 4. NEXT LINE? Type in the second line of the label and press ENTER. If no second line is needed, just press ENTER. The DATA and CTRL arrow and its label will now be drawn. Follow instructions 2 - 4 to place more parameters on the chart. When finished with the ADD DATA or CTRL mode, press ESC to return to the full menu. VII. Print a Chart Return to the Add Menu and press ATL + F6 to print your chart. If you want to print the entire chart, you should be at full scale - press CNTL + F3.

To exit from these functions, press ESC until you are returned to the menu desired. PLOTTING/PRINTING Plotting SCdraw supports multiple plotters; refer to the chapter 'System Requirements'. The plotting function can be activated from the Other Menu under the function REDRAW. See The Redraw Function in the section OTHER MENU for more explanation. Setting of baud rates and parity are outlined in the following table: PLOTTER BAUD RATE PARITY --------------------- --------- ------ Hewlett Packard 7220 2400 None Hewlett Packard 7470A 9600 None Hewlett Packard 7475A 9600 None Hewlett Packard 7550A 9600 None Hewlett Packard ColorPro 9600 None Hewlett Packard Draftmaster 9600 None IBM 7371 9600 None IBM 7372 9600 None Sweet Pea Six-Shooter 9600 None For information on how to set the dip switches, refer to the your respective plotter manual. Also the plotter has to be identified to SCdraw through the configuration setup. If this has not been done, refer to Setting Configuration. Color Definitions SCdraw uses seven logical colors. The default colors used for the various symbol types are shown in the following table. ----------------------------------------------------------------------- Symbol Default Color Type ----------------------------------------------------------------------- Module White Link White Loop White Diamond White Boundary Green Page Connector White Text Blue Data Red Control Blue ----------------------------------------------------------------------- The correspondence between color and plotter pen number used is shown in the table below. ----------------------------------------------------------------------- Color Color 2-Pen-Plotter 6-Pen-Plotter 8-Pen-Plotter No. Pen No. Pen No. Pen No. ----------------------------------------------------------------------- Red 1 1 1 1 Green 2 2 2 2 Blue 3 1 3 3 Cyan 4 2 4 4 Yellow 5 1 5 5 Magenta 6 2 6 6 White 7 1 1 7 Note: If a symbol is highlighted, it will use pen number 1 on the 2-Pen-Plotter; pen number 5 on the 6-Pen-Plotter and on the 8-Pen-Plotter. Printing The print function generates a hardcopy of the current screen display via an attached printer. The ZOOM and PAN functions can be used to isolate sections of a diagram for hardcopy display. There are two print resolutions available for most of the printers supported by SCdraw. To print, press either: CTRL + F5 Standard resolution CTRL + F6 High resolution (For the Toshiba printers, standard = high) Gives the clearest printed diagrams but is slower than the single density used with CTRL + F5. Note: HP LaserJet Series II and III require a total of 2 Meg of printer memory for high resolution printing. Note: Printer must be attached to a parallel port. USING A MOUSE The mouse pointing device will function with both menu selection and graphic editing. The mouse buttons can be used in place of the keyboard keys as defined below: ----------------------------------------------------------------------- Keyboard 3-Button 2-Button Key Mouse Mouse ----------------------------------------------------------------------- ESC Click left button Click left button ENTER Click right button Click right button + Hold left button and Hold left button and click right button click right button - Hold right button and Hold right button and click left button click left button INS Click middle button Hold either button and click the other ARROW KEYS Movement of mouse Movement of mouse ----------------------------------------------------------------------- Menu Selection Move the mouse highlighting the menu selection and click the ENTER button. ZOOM Function The plus (+) and minus (-) keys are used with the zoom function to increase or decrease the size of the zoom box, respectively. The mouse can be used to replace the usage of these two buttons as defined in the above table. Graphic Editing The mouse will function with the graphic editor for symbol location and usage of the ENTER, ESC, and INS keys. For symbol location, use the mouse to move the cursor to the appropriate position. Use the buttons as noted in the above table to represent the ENTER and ESC keys defined for each appropriate symbol selection process. Use of the mouse to represent the INS key will be active except in the Zoom mode on the 2 button mouse. The INS key is used to toggle movement of the graphic locator between high and low precision. General Notes The mouse is an optional feature with SCdraw. All input can be entered through the keyboard if a mouse is not available. All menus and editing features as defined in this manual remain the same. If a mouse is used, note above listed table to identify appropriate usage. Mouse Requirements A mouse may be used as an additional input device with SCdraw. Both Microsoft's and Mouse Systems' mice are supported. However, before initiating the SCdraw session, the vendor's mouse device driver must be made resident following instructions supplied by the vendor. For the Microsoft mouse, the driver is named MOUSE.COM; the Mouse Systems driver is named MSMOUSE.COM. Most users include a line in the AUTOEXEC.BAT file so that the driver will automatically be made resident when the system is booted. ERROR MESSAGES ADJUST PAPER. ENTER TO CONTINUE - Adjust paper on printer to top of form Press ENTER to print or CTRL + Break to stop the print function. CANNOT DELETE FILE - Error in file or disk structure. Try to delete again or try to delete from DOS. CANNOT OPEN FILE - File is in wrong format. It is not an SCdraw chart file. CANNOT PAN AT FULL SCALE - You are currently at full scale mode with the chart. You must be in the ZOOM mode (use CTRL+F2) before PAN can be used. CANNOT RENAME FILE - There is a possible error in the file or disk structure. Try to rename the file again or try DOS RENAME. CHART ALREADY EXISTS - The chart you are trying to create or rename already exists. Retry this function with a new name. Use the DIR function under the CHART menu to view the current file names that exist. CHART NOT FOUND - The chart name entered was not found on the disk and directory currently in use. Use the DIR function under the CHART menu to check the spelling of the chart names and/or use the DRIVE and CHANGE DIR functions to change to the correct directory, if necessary. DEVICE DRIVER NOT COMPATIBLE WITH INSTALLED EQUIPMENT - The configuration you have estabished in the SC.BAT file does not match your actual PC equipment. Review the bat file and update it to match your equipment. DEVICE ERROR ON ASYNC PORT - You have encountered an error while plotting. Check the following conditions: 1) Be sure the correct communications port number is entered when prompted for; 2) Be sure plotter is turned on and in a ready state (paper loaded); 3) The switch settings on the plotter must be correct - see the plotter manual; 4) You must use the correct cable as specified by the plotter manufac- turer. DIRECTORY NOT FOUND - The directory specified in the CHANGE DIR function does not exist. Display the directory of the disk and check the spelling. DISK SPACE OR R/W ERROR - The disk is full or you have encountered an error while reading or writing to the disk. DISPLAY LIST MEMORY BUFFER FULL-You have run out of memory for displaying your current chart on your PC.You may need additional memory (>320K) to add more symbols to your chart. The maximum number of symbols allowed is 800 and requires more than 320K of memory. To gain more memory, you might check for any resident programs running in memory and eliminate those or if possible, add more memory to your machine. FILE ALREADY EXISTS - The file already exists for this chart name entered. Retry the name with a new name. Use the functions provided in the CHART menu to aid this process--DIR, CHANGE DIR, and DRIVE. ILLEGAL DRIVE - The specified disk drive does not exist. Check the existing drive and try again. Input the letter only (for example: A, B, C, etc.) ILLEGAL SYMBOL TYPE - The function specifed is not valid for the symbol type chosen. For example: 1) MOVE function is not valid for links, loops, diamonds, boundaries or data & control parameters. To `move' these symbols, use the CHANGE function and select the type of symbol to be `moved'. 2) DUPL function is not valid for links, loops, diamonds, boundaries, or text. To create these additional symbols, use the ADD menu. 3) LINKS can connect only modules and off page connectors. INVALID HEIGHT - The point chosen for height is at or below the level of the point chosen for the text position. The point chosen for the position for the text represents the botton of the text. The point chosen for HEIGHT: must be above the first point. The vertical distance of these two points is the text height. INVALID NAME - The name entered for the chart does not conform to DOS file name standards. It must be 1-8 alphanumeric positions. INVALID NUMERIC INPUT - The value(s) entered are less than 0 or the entry is invalid. Size of a chart must be entered as #,# (for example: 10,12) INVALID SIDE - Loops and diamonds must be placed on the bottom side of the module boxes. MAXIMUM CONNECTIONS ALREADY ESTABLISHED - The maximum number of connections has been exceeded. One of the following conditions has occurred: 1) The number of data or control arrows assigned to a link has exceeded 20. 2) The sum of the number of links, diamond and loop connections to a module or off-page connector has exceeded 100. MAXIMUM NUMBER OF SYMBOLS EXCEEDED - The maximum number of symbols is 800 per chart and this limit has been exceeded. No more symbols can be added until others have been deleted. To expand your charting capability, use the off page connector to go to another chart or the LEVEL function to expand a chart in more detail on another chart. NO SYMBOL DETECTED - One of the following conditions has occurred: 1) During a PICK SYMBOL function, the graphic locator was not placed on a symbol. (The tip of the locator must be on the symbol you wish to choose--touching labeling information or a line segment); 2) The point chosen for the SOURCE or DESTINATION of a link did not touch the symbol (module or off page connector). 3) During the CHANGE function of a loop or diamond, the LOCATION picked did not touch the module box selected. 4) During the CHANGE function of a data or control parameter, the LOCATION picked did not touch the data or control selected. 5) During the LEVEL function, the graphic locator did not touch the module box to be expanded. 6) The point chosen to add a data or control symbol to the chart did not touch the link this symbol is to be associated with. The graphic locator must touch the link line segment though the data or control arrow will actually be drawn off the link. PLOTTER SUPPORT MODULE ABSENT - The plotter module must be included in the SC.BAT file to be able to output charts to a plotter. See Setting Configuration. POINT NOT ON SAME SIDE - The point chosen for the end point for the loop must be on the same side of the module as the beginning point. UNABLE TO LOAD SCdraw - Random Access Memory (RAM) was exceeded. SCdraw needs a minimum of 320K of RAM to execute. If you have other resident programs in memory when loading SCdraw, these programs may take up some of the RAM and not leave enough for SCdraw. Reboot the PC without loading the other programs and try to load SCdraw again. UNSUPPORTED MONITOR DEVICE - Monitor device specified in SC.BAT file was not found on the default disk drive. Verify the correct monitor driver exists on the diskette or in the SCdraw directory. Also check the correct spelling of the driver. See Setting Configuration for correct syntax of the SC.BAT file. UNSUPPORTED PLOTTER DEVICE - The plotter module specified in SC.BAT file was not found on the default disk drive. Verify the correct plotter driver exists on the diskette or in the SCdraw directory. Also check the correct spelling of the driver. See Setting Configuration for correct syntax of the SC.BAT file. UNSUPPORTED PRINTER DEVICE - The printer module specified in the SC.BAT file was not found on the default disk drive. Verify the correct printer driver exists on the diskette or in the SCdraw directory. Also check the correct spelling of the driver.
