What does that mean? Literally, TheDraw makes designing and figuring out a video screen display childs play. Its basic premise is this: be easy to use. The most novice computer user can make an Ansi text file screen with TheDraw in only minutes. From that point on, you can explore and use more of the horsepower available in TheDraw. Someone is probably saying "it edits screens... big deal". This type of person has never known the agony of creating a good looking menu or display for a program (assuming he/she programs), making a fancy batch file intro screen, or having to quickly putting together a computer presentation for the boss. The biggest problem facing most people is we really do not know what will look good until we see it. Manually editing a screen can literally take hours. With TheDraw, you can free form until you really know what is perfect. With the picture in mind, you can quickly develop whatever is necessary or instruct TheDraw to create a data file which can be used. Instead of hours, making a screen takes minutes. For the curious, TheDraw can transform your masterpiece into data files with the following formats: ANSI color text (useful in batch files, BBS's, etc...) ASCII text (compatible with word processors and text editors) BINARY files (generic, useful in most everything) BSAVE (for Basic) COM files (actual separate programs that may be executed directly by Dos. Great for batch files.) ASSEMBLER (for the die-hard coder) TURBO PASCAL (directly compilable source code) C (format is for Turbo C specifically) THEDRAW (custom storage format for FAST loading and saving) TheDraw was long ago originally written as an improvement to a simple program named AnsiDraw written by Amrich Enterprises. Both programs provided similar operation, with TheDraw giving a much enhanced user interface. TheDraw v3.20 Introduction 1 TheDraw is now vastly improved over the abilities of AnsiDraw, and most other screen editors. It is compatible with most systems that have 150k of free memory available. Monochrome and Color monitor users are supported, and a special keyboard driver allows you to redefine keystrokes that do not operate properly or are used by other programs (registered version). Another feature TheDraw fully supports is ANIMATION. With this facility you can develop quick and dirty presentations, or simply make a generic screen appear with pizzazz. You can either let TheDraw make an animation sequence from an image, or one can be made from scratch; thus letting you fully control the appearance of your work. TheDraw gives you a maximum of 16000 separate animation "entries" to handle the most complex job. The final result can be saved either as an ANSI file (Ansi Animation) or TheDraw format file. See the section entitled "The Animation System" for more information. To get started using TheDraw right away, refer to the section entitled "Starting TheDraw". This section describes how to install and run TheDraw. Enjoy! TheDraw v3.20 Introduction 2 D E F I N I T I O N S Throughout this documentation you may run across the occasional enigmatic word that needs explaining. The following are some examples you might come across: enigmatic - mysterious or cryptic [ENTER] or C/R - This represents the return key on the keyboard. If you see this in the text, press the Enter key; do not type the actual letters. ESC or [ESC] - Means to press the ESC key on the keyboard. [letter] - Means to press the actual key marked 'letter' on your keyboard. ie: [L] means to press the 'L' key. Alt-[letter] - Alt- is always followed by another character. Together, this symbol means to first press and hold down the ALT key on the keyboard then type the letter key following it. ie: Alt-A means hold down ALT then press 'A'. Ctrl-[letter] - This is executed the same as the ALT key. or ^[letter] Press and hold down the CTRL then hit the letter following. ie: CTRL-A and ^A mean the same thing - hold CTRL then press 'A'. TheDraw v3.20 Definitions 3 S Y S T E M R E Q U I R E M E N T S TheDraw requires an IBM PC/XT/AT or close compatible running MsDos 2.0 or higher. In addition, a Color Graphics or Monochrome adapter plus monitor is needed to run properly. In a minimum configuration, 150 kilobytes of free memory are required. The maximum memory usage is 330k of memory (8 page layers, 16000 animation entries). Any remaining memory can be used to execute a Dos Shell if desired. TheDraw will always attempt to allocate all available memory up to the limits specified using the Setup utility. MULTITASKING ENVIRONMENTS ______________________________________________________________________ TheDraw can be used under multitasking or windowing environments provided the full video screen is allocated to it. The program directly accesses video memory and the keyboard hardware for some of its functions. TheDraw is known to operate under Double Dos except for minor problems. Double Dos disables certain keyboard sequences (notably Ctrl-PrtSc). For this situation, people with the registered version of TheDraw can use the Setup utility to redefine the function of Ctrl- Prtsc to another key. TheDraw operates under Microsoft Windows and Desqview provided memory and video requirements (as mentioned above) are taken care of. Note: It is easily conceivable to cause problems with window environments if the user wishes. Working in another window while TheDraw attempts to refresh its screen will result in information being overwritten. Be warned. Proper support for window environments will be provided in the future. TheDraw v3.20 System Requirements 4 G E T R U N N I N G Setting up TheDraw to operate on your computer is not a great chore. Refer to the section below that applies to you. If you received TheDraw on diskette, it is suggested you backup the disk before proceeding. It never hurts to play it safe. The diskette obtained from TheSoft contains a batch file called INSTALL.BAT to simplify this initial setup (note: INSTALL.BAT is not included with the shareware version of TheDraw). FLOPPY DISK INSTALLATION ______________________________________________________________________ If you obtained a diskette from TheSoft, you are almost set to go. You will want to copy all the files onto the diskette you will be using frequently. Because of space requirements, the setup utility, documentation and demo files are compacted. Use the INSTALL batch file to expand these files onto another diskette. ie: INSTALL FLOPPY <enter> Simply follow the online instructions presented. Once done, proceed to the section "The Setup Utility". HARD DISK INSTALLATION ______________________________________________________________________ Create a sub-directory of your choice to place TheDraw and files in. Next, copy all files to the sub-directory. Example commands are: MKDIR \THEDRAW Create a sub-directory THEDRAW in the root directory of your hard drive. CHDIR \THEDRAW Put Dos into the THEDRAW sub-directory. COPY A:*.* Copy all files from drive A to the sub- directory. Details of the above commands will not be covered here. Please refer to your Dos manual if you have questions. On the diskette obtained from TheSoft, there is a batch file to simplify this process. With the diskette in drive A, type: INSTALL HD <enter> This will do all of the above for you automatically. TheDraw v3.20 Get Running 5 MAKE IT DO SOMETHING! ______________________________________________________________________ By this point you may be eager to start playing with TheDraw; by all means do so. Use of the Setup utility is not absolutely necessary unless TheDraw does not appear to run properly. To run TheDraw simply type from the Dos prompt: THEDRAW [ENTER] People with the registered version type: THEDRAWR [ENTER] After a few seconds, TheDraw will start running and display its title screen. Press a key, and TheDraw is ready. Quickly, two commands you should be familiar with are: ALT-S Save Screen to Disk ALT-X Exit TheDraw The former will save your efforts to disk. The latter will allow you to exit TheDraw back to Dos. Have fun! THE DEMO FILES ______________________________________________________________________ TheDraw comes with two demonstration files to help show some of its capabilities; SHUTTLE2.ANS and DEMO.TD. SHUTTLE2.ANS is a simple animation example which you can view from dos by entering: TYPE SHUTTLE2.ANS [Enter] Note: You must have the ANSI.SYS driver installed in your CONFIG.SYS file for this to appear properly. See APPENDIX A for more details on the CONFIG.SYS file. If you do not have Ansi.Sys, THEPP (provided with registered version of TheDraw) can be used alternatively (ie: THEPP SHUTTLE2.ANS [Enter]). The second demo file, DEMO.TD, demonstrates the block editing features of TheDraw. To use it, run TheDraw as described above. Next, press ALT-L and type DEMO.TD [ENTER]. Instructions will appear on screen showing what to do next. TheDraw v3.20 Get Running 6 MOVING TO THEDRAW VERSION THREE AND BEYOND ______________________________________________________________________ Users of TheDraw versions 2.0, 2.1, or 2.2 will be able to start using version 3.0 and above right away. The only things the user should be aware of are the revised ALT-E command, and the block copy/move "exchange" command. To flip page layers, the wanted layer must be specified. This differs from the older versions which merely toggle between the available pages. There are many new additions to TheDraw. Some will be apparent (such as the Last block option); some will not. The following is a list of new features added to TheDraw version 3.00 through 3.20: o Multi-Layer sprite editing - Supported in both normal AND animation modes. o Five new animation screen scanners - Angle, Gate, Pyramid, Squares and Wiggle. o Ability to shell to Dos. o Ability to append one animation file onto the end of the current animation file in memory. o Global screen copies now supported in animation mode along with the layered editing mentioned above. o Use of the "Last Block" specified. o THEDRAW format files. These files store the complete configuration of TheDraw when the file was saved. This includes the current colors, tab line, cursor position, etc... Useful for quickly saving an animation file or all the current page layers. o Animation Markers, Include Files, and Pausing. TheDraw v3.10 adds: o MicroSoft Mouse Support o Full screen Ansi file saving o Five new function character sets for a total of 15! TheDraw v3.20 Get Running 7 TheDraw v3.20 adds: o Compute pull down menu system for ease of learning. o "Sticky" wildcards in the directory listings (see ALT-L). o COM file save screen format (see ALT-S). Plus much more! FILE LISTING ---------------------------------------------------------------------- The following briefly describes the contents of the shareware self- extracting archive: READ.ME Contains last-minute notes and corrections, plus any special instructions needed. MAILER Prints out a registration form on your printer that can be folded and mailed directly. WHATSNEW.DOC Gives a brief listing of major additions to TheDraw in this latest version. DEMO.TD Example files. Refer to THE DEMO FILES. SHUTTLE2.ANS PRINTDOC.EXE Program that simplifies the printing of these instructions. Type PRINTDOC [Enter] from Dos. SETUP.EXE TheDraw Setup utility. Refer to section below. THEDRAW.EXE Shareware version of TheDraw. THEDRAW.DOC This documentation file. UNCRUNCH.ASM These files contain implementations of the uncrunch UNCRUNCH.PAS algorithm needed to display screen images crunched UNCRUNCH.H by TheDraw. UNCRUN_N.OBJ UNCRUN_F.OBJ TheDraw v3.20 Get Running 8 T H E S E T U P U T I L I T Y This section describes how to customize TheDraw and install your customizations in the THEDRAW.EXE or THEDRAWR.EXE (registered version only) files. WHY SETUP? ______________________________________________________________________ Setup is the TheDraw installation program; used to customize the TheDraw program (EXE) file. With this utility you can specify screen modes, change edit colors and various other defaults. Setup allows you to change the TheDraw environment in which you operate. It also directly modifies various values within your copy of THEDRAW.EXE or THEDRAWR.EXE. Via Setup you can do the following: o Setup the default video display mode o Change screen colors o Resize TheDraw's usage of available memory o Change save screen default parameters. o Specify initial default filespec wildcards. In the registered version of TheDraw, the Setup utility can also: o Customize or "remap" the editor command keys and mouse buttons. o Setup a path to the directory where help files are stored. TheDraw comes ready to run; there is no mandatory installation. After setting up as specified in GET RUNNING, you can run TheDraw. However, you will need to run Setup if you want to do any of the following: o Change TheDraw default colors. o Force a display mode or "snow" checking o Customize the editor commands to preferred sequences. o Adjust memory usage to better suit your needs. TheDraw v3.20 The Setup Utility 9 WINDOWS AND SELECTING OPTIONS ______________________________________________________________________ The setup utility operates in a windowing user environment. You select commands by either pressing the highlighted capital letter of a given option, or using the Up and Down arrow keys to move to your selection and then pressing [ENTER]. For instance, from the main Setup installation menu you can select Editor configuration*, Keyboard customize, Screen mode, Colors, Help and overlay file path*, Memory usage, Defaults, or Quit/Save. * Available while editing the registered version only. SAVING AND ABORTING CHANGES ______________________________________________________________________ In general, pressing [ENTER] will save any changes. Pressing [ESC] (as many times as needed) will abort a function and return you from a submenu to the main installation menu. Where this convention is not followed, instructions are displayed on the screen for you. RUNNING SETUP ______________________________________________________________________ To get started, type SETUP [ENTER] at the DOS prompt. Once the utility runs, you will be prompted for the filename to modify. This allows you to have several different customized copies of TheDraw on your system. These various copies of THEDRAW.EXE can each have different executable program names. This allows you to customize for various editor command-keys, menu colors, etc... if you are so inclined. The registered program is called THEDRAWR.EXE. After selecting a file to edit, SETUP determines what version of TheDraw is being updated (shareware or registered). It then proceeds to the main menu. TheDraw v3.20 The Setup Utility 10 RUNNING SETUP: MAIN MENU ______________________________________________________________________ The main menu presents several options. Each item on the menu is described below: EDITOR CONFIGURATION The editor in TheDraw provides many features, including cursor control, color changing, various text operations, etc... These editing commands are assigned to certain keys, as described in this documentation. This option allows you to change the default assignments for each function. When you select Editor Configuration from SETUP's main menu, the editor installation screen appears. Three columns of information will be immediately notable: o The first (left-most) column describes each configurable function available in the editor. o The second column lists Primary keystrokes. These keys are the defaults by which TheDraw normally operates. o The third column lists Secondary keystrokes. These are optional alternates keystrokes you may press to invoke a given editor action. These keystrokes always take precedence over the primary keystrokes described above. Along the bottom of the screen is a list of the keys used to select and modify entries. Key Action _______________________________________________________________ Up and Down Selects the editor command you wish to change. arrow keys PgUp/PgDn Scrolls up/down one full screen page. [ENTER] Enters the secondary keystroke modify mode. R Restore all editor commands to the original default values. [ESC] Returns to the main SETUP options menu. _______________________________________________________________ TheDraw v3.20 The Setup Utility 11 After pressing [ENTER] to modify a command, the current secondary definition disappears. You can then type in your new definition. Anything may be used for redefining a key except Numbers (0-9), Letters (A-Z,a-z), Enter, Esc, and Backspace. A maximum of four keystrokes for any given editor command is allowed; however, certain key combinations are equal to two keystrokes. These include ALT-(key), cursor movement keys (up, PgDn, Home, etc...) and any keystroke involving a function key (F1, CTRL-F4, etc...). Upon pressing ESC, if anything has been changed you are prompted to save the changes. Next, if there are any duplicate keystrokes SETUP will point out the first occurrence so you can clear up the problem (marked with an asterisk). KEYBOARD CUSTOMIZE The true IBM-PC and certain clones have a Bios bug preventing the Ctrl-Up and Ctrl-Down keystroke combinations from working properly. TheDraw gets around this by using a custom keyboard driver. SETUP examines the keyboard hardware to see what happens when Ctrl-Up and Ctrl-Down are pressed. Upon selecting this option, the screen clears and prompts if you wish to continue. Next you are requested to press Ctrl-Up and Ctrl-Down in that order. SETUP will display scan codes returned by your keyboard for those keys. Next you can experiment to see that everything is indeed working properly. Press Ctrl-Up/Down until satisfied you programmed the correct keys. When ready press [ENTER] to return to the main menu. SCREEN MODE Normally, THEDRAW will automatically determine the correct video mode of your computer. You should only need to change the Screen mode option if: o you think TheDraw is incorrectly detecting your hardware. o you have a Color Graphics Adapter (CGA) that does not produce the "snow" effect. o your computer has a composite video screen, which acts like a CGA with only one color. In this case, you want the Black and White screen option. TheDraw v3.20 The Setup Utility 12 Upon pressing S to select this option, a pop-up menu will appear with the available options. These are fairly apparent: DEFAULT TheDraw will operate in the mode active when first run. BLACK AND WHITE TheDraw will use composite black and white mode (80 column), regardless of the active mode when first run. The original video mode will be selected when you exit TheDraw. COLOR TheDraw will use color mode (80 column), regardless of what mode active when first run. The original video mode will be selected when you exit TheDraw. MONOCHROME TheDraw uses monochrome video mode, and switches back to the previous mode upon exiting. After selecting one of the first three options above (Default, B&W, or Color), SETUP checks the screen for snow. If you see snow or hashing, respond Yes to the prompt that appears. COLOR CONFIGURATION TheDraw holds three complete sets of configurable colors. Which color set is used depends on the initial screen mode specified above. The sets are for Color, Black and White, and Monochrome screen users. A pop-up window prompts for which set to edit. After selecting a color set, another pop-up window appears. These choices are for the type of item you wish to configure. The Edit Screen, Main Help Display, Directory (Load/View) Screen, and Pop-up help if configuring the registered version of TheDraw. Choose the item type to edit. Next, you will see a menu of configuration items under that type. Selecting a menu item will display a view port and list of available colors. The view port shows an example of the screen TheDraw v3.20 The Setup Utility 13 item you chose. It also reflects any changes in colors as you scroll through the color palette. Use the arrows keys to select a color to your liking from the palette. Watch the view port to see how the item looks in that color. Press [ENTER] or [ESC] to save your choice. Now repeat this procedure for every screen color item you want to customize. When done, press [ESC] until you return to the main SETUP menu. HELP DIRECTORY This option only appears when you are editing the registered version of TheDraw. With the Help Directory you can specify a path for TheDrawR to locate its help, overlay and macro key files. The current setting is displayed for you. To change it, simply type in the new directory. Enter a period (.) by itself to use the current directory when TheDraw is loaded. Press [ENTER] without entry to leave unchanged. MEMORY USAGE TheDraw always tries to allocate all available memory up to limits specified by this SETUP option. When fully configured, TheDraw can use as much as 330k of memory. Memory is allocated first for screen page layers and then for the animation system. If you have limited memory, there might not be enough space for 8 page layers, 16000 animation entries and Dos Shell (maximum usage). There may however be enough space for 4 page layers and 5000 animation entries, or one layer and a Dos Shell, or anything in between. This is when you may wish to override the automatic memory allocation. To make TheDraw operate as in earlier versions, you would want just 2 page layers and 5000 entries. Feel free to experiment. Keep in mind that TheDraw will scale down all settings when loaded if there is not enough memory. Upon selecting this option the current settings are displayed for you. The amount of memory occupied by screen page layers and the animation system is also indicated. If you wish to change them answer Yes to the prompt. You can then enter new values for both. TheDraw v3.20 The Setup Utility 14 DEFAULTS TheDraw has certain default values used throughout the program. Some of these are: o Initial edit colors o Default file extensions o Default file save parameters o Sticky directory wildcards etc... Selecting Defaults from the main menu displays a screen with several fields. Use the up and down arrow keys to select the field you wish to change. PgUp/PgDn switches between the two screens of options. To change a value follow the on screen directions. Pressing "R" at any time restores all "factory" defaults. Press [ESC] when satisfied with your changes. QUIT/SAVE Once all changes are completed, select Quit/save at the main SETUP menu. The message: Save Changes? (Y/N) appears along the bottom line of the screen. Reply Yes, and all the changes you have made will be saved into TheDraw. Reply No, and all your changes are ignored. After either reply, you are return to the operating system (Dos). If you ever decide to reset TheDraw completely to factory defaults, simply copy the EXE program file from your original disk (you did make one right?) onto your work disk. If you just want the editor commands restored, select the R command under Editor Configuration. TheDraw v3.20 The Setup Utility 15 S T A R T I N G T H E D R A W COMMAND LINE FILESPECS ______________________________________________________________________ For convenience, TheDraw allows you to specify a filespec from Dos when first running the program. ie: THEDRAW DEMO.TD Only one file may be specified this way. All files are loaded onto page layer one (except for THEDRAW format files, which are discussed under the ALT-S command). THE STATUS LINE ______________________________________________________________________ The status line of TheDraw shows various information about the state of the program. Each structure in the status line is described below: (xx,xx) Displays the current cursor position. Color Indicates the current drawing color. This color is used for any new characters placed onto the screen. Text or Which word is displayed indicates if TheDraw is in Draw normal Text or line Draw mode. In Draw mode, moving the cursor with the arrow keys draws a line in the moved direction. Ins Appears when TheDraw is in Insert keystroke mode. In this mode, typing a character shifts everything to the right to make room for the new character. Page:x or Indicate the current screen page edit layer. In Anim:x animation mode (see The Animation System for more details), the word Anim appears. In addition, this structure indicates when TheDraw is in sprite edit mode (see ALT-E). In sprite mode, either message will appear in capital letters. ie: PAGE or ANIM. Set:xx Number of the current function key set. This set appears immediately after this indicator. Note: The symbol "x" or "xx" indicates a number of some value. TheDraw v3.20 Starting TheDraw 16 HELP!!! ______________________________________________________________________ The shareware version of TheDraw contains two outline help screens available from command mode (no other commands being used) by pressing ALT-H. These outline screens display brief notes about all operations available in the program. The registered version of TheDraw supports context sensitive help. In other words, pressing ALT-H absolutely anywhere in the program will bring up specific instruction on that area of TheDraw. This can be very useful during the initial learning of the program or for rarely used functions. CURSOR CONTROL ______________________________________________________________________ The cursor may be moved by using the following keys: Key Action _____________________________________________________ Up Arrow Up one line Down Arrow Down one line Left Arrow Left one position Right Arrow Right one position Home First column of current line End Last column of current line PgUp First line in current column PgDn Last line in current column Ctrl-Home First Character of current line Ctrl-End Last Character of current line (plus 1) Ctrl-PgUp Upper-left position of screen Ctrl-PgDn Lower-right position of screen Tab Next set Tab position (see Alt-T) Shift-Tab Previous set Tab position (see Alt-T) Enter First column of following line _____________________________________________________ Naturally, if you attempt to move past the screen border no action will be taken. If no tab position follows the current location, pressing [TAB] will return you to column one of the current line. TheDraw v3.20 Starting TheDraw 17 MOUSE CONTROL ______________________________________________________________________ TheDraw v3.2 fully supports the use of a Microsoft Mouse or compatible device. Pull down menus and other facilities are available (see section PULL DOWN MENU SYSTEM). You may use either a two or three button mouse with TheDraw. The mouse operates differently depending on where you are in TheDraw. At the normal editing screen (no sub-function active) the mouse functions are: MOVEMENT: Moves cursor. LEFT BUTTON: Marks a block. MIDDLE BUTTON: Toggles line drawing mode RIGHT BUTTON: Activates pull down menu system. In any sub-function: MOVEMENT: Moves cursor/block/screen/whatever... if something can move, you can use the mouse. LEFT BUTTON: Equivalent to pressing [ENTER] MIDDLE BUTTON: Unused. RIGHT BUTTON: Pops a small window with current menu options. Someone comfortable with using a mouse will find TheDraw easy to get used to. The mouse may used everywhere in the program. If no particular mouse indicator appears, pressing the RIGHT mouse button will generally pop up a window with available options. Simply clicking the RIGHT button on the wanted option will select it. Users without a mouse will find TheDraw operates as before without change. Note: The mouse driver (MSMOUSE.SYS or similar program) must be installed into your CONFIG.SYS file before TheDraw will recognize the device. See APPENDIX A for information on configuring Config.Sys. Once the driver is installed, TheDraw auto-detects the presence of the mouse so it can be used. TheDraw v3.20 Starting TheDraw 18 COMMAND SUMMARY ______________________________________________________________________ TheDraw provides the following 33 command functions, available through ALT-Letter or CTRL-Letter key sequences plus a pull-down menu system.

ESC Activate pull-down menu system from keyboard. The section THEDRAW KEYBOARD COMMANDS on the following pages contains explanations for each of the above. TheDraw v3.20 Starting TheDraw 19 P U L L D O W N M E N U S Y S T E M ----------------------------------------- Starting with version 3.2, TheDraw can be fully controlled by use of pull down menus. The menus can greatly simplify the learning of TheDraw by conveniently showing all related commands. The pull down menus are activated from command mode using one of two ways. Pressing either the [ESC] key on the keyboard or the RIGHT-most mouse button (if using a mouse). The following options bar will appear across the top of the screen: ┌─────────────────────────────────────────────────────────────────┐ │ Files Global Options Screen Animation Color Toggles Help │ └─────────────────────────────────────────────────────────────────┘ Each heading is described briefly below. For full functional descriptions, please refer to the appropriate section under THEDRAW KEYBOARD COMMANDS. The FILES Menu ---------------------------------------------------------------------- The Files pull-down menu offers assorted options for loading or viewing existing files, deleting old files, and saving the screen image currently being edited. When you load a file, it is read into the screen edit area. When done with a file, you can save it to any directory or file name. In addition, from this pull-down you can change to another directory, temporarily go to a Dos Shell, or exit TheDraw completely. ┌────────────┐ │ Load │ │ View │ │ Delete │ │ Change Dir │ │ Save │ │ Quit │ └────────────┘ LOAD - Load a File (ALT-L) Displays a list of files under the current directory. You can use DOS-style masks to get a listing of specific files you want. Simply type in the name of the file you want to load or use the arrow keys to move the and press [ENTER]. VIEW - View a File (ALT-V) Similar to Load, except the image loaded is only temporary. Pressing [ENTER] returns to command mode. TheDraw v3.20 Pull Down Menu System 20 DELETE - Delete a File (ALT-K) Allows files to be deleted from within TheDraw. The screen operates identically to the LOAD option above. The difference being TheDraw will attempt to delete any file you select. CHANGE DIR - Change Working Directory (ALT-O) Displays all subdirectories in the current directory. Select the wanted directory by typing it in or using the arrow keys to select. To change to another drive, simply type the wanted drive followed by a colon. ie "C:" SAVE - Save Current Screen to a File (ALT-S) Saves current screen image to one of a variety of file formats. QUIT - Quit/Shell from TheDraw (ALT-X) Allows you to either exit TheDraw completely or simply leave the program temporarily. In both cases, you end up at the Dos prompt. To return to TheDraw from a Dos Shell, type EXIT. This is useful when you want to run a DOS command with quitting TheDraw. The GLOBAL Menu ---------------------------------------------------------------------- The global menu offers options that affect the entire edit screen. These options include moving and copying the screen, plus global screen fills and text operations. ┌──────┐ │ Copy │ │ Move │ │ Fill │ │ Text │ └──────┘ COPY - Global Screen Copy (ALT-G, option C) Copies the current screen page to another page. You are prompted for which destination page you want. TheDraw v3.20 Pull Down Menu System 21 MOVE - Global Screen Movement (ALT-G, option M) Allows the rotating of the screen around its borders. Use the arrow keys or the mouse. Press [ENTER] or the LEFT mouse button to save at the new location. FILL - Global Fill Screen (ALT-G, option F) Fills the entire screen based on a specified sub-command. The available options allow just the color attributes, just the characters, or both to be changed at once. TEXT - Global Text Operations (ALT-G, option C) Performs various screen text operations. Available sub-options are: Draw Box, Outline contents of screen, Center Justify screen contents, Left Justify, and Right Justify. The OPTIONS Menu ---------------------------------------------------------------------- The Options menu contains facilities to aid you in the layout of a screen design. Commands affect things like the current character set, the Tab line setup, and the on-screen ruler. A screen painting function is available also. ┌───────────────┐ │ Character Set │ │ Tab Setup │ │ Ruler │ │ Paint/Fill │ └───────────────┘ CHARACTER SET - Display and Select Character Set (ALT-F) Shows a screen containing all special symbols in the IBM extended character. From this you can select which character set you would like to work with. Use the arrow keys or the mouse. Press [ENTER] to save your choice. TAB SETUP - Adjust TheDraw Tab Stops (ALT-T) This command permit the setting of tabs in the editor (positions where the [TAB] key stops). Initially the positions are at every tenth column. Sub-commands are available for setting, clearing, and resetting tabs. TheDraw v3.20 Pull Down Menu System 22 RULER - On-Screen Ruler (ALT-N) Places a pair of lines on the screen which intersect at the cursor position. Move the ruler using arrows or the mouse. [ENTER] saves the new cursor position. This command is useful for aligning items of the screen. PAINT/FILL - Enclosed Area Painter (ALT-P) Lets you fill an enclosed area easily with characters and/or color attributes. An area is defined as any shape formed using line characters (from function key sets 1-4). To use this command, position the cursor inside the target area before activating the pull down menus. The SCREEN Menu ---------------------------------------------------------------------- Use items in the Screen menu to erase a page layer or select some other page. Other options allow you to insert, delete, or restore the contents of individual lines. ┌──────────────┐ │ Clear Page │ │ Select Page │ │ Insert Line │ │ Delete Line │ │ Restore Line │ └──────────────┘ CLEAR PAGE - Clear the Current or All Page Layers (ALT-C) Erases the image in the current page. You may also opt to erase all page layers in one fell swoop for a completely clean slate. You will be prompted to save the current screen if changes have been made. SELECT PAGE - Choose a New Page to Work On (ALT-E) TheDraw prompts for the page layer you wish to edit. Enter a number between 1 and the number of available pages, or use the mouse. INSERT LINE (ALT-I) Inserts a blank horizontal screen line at the position of the edit cursor. This command is not reversible so use it carefully. TheDraw v3.20 Pull Down Menu System 23 DELETE LINE (ALT-Y) Similar to Insert, but deletes the line rather than inserts a new one. RESTORE LINE - Recover from Unwanted Changes on the Screen (ALT-R) Brings back the previous copy of the horizontal line currently being worked on. Please note that once you leave a line, all changes are permanent. The ANIMATION Menu ---------------------------------------------------------------------- Provides various facilities for working with the TheDraw animation system. Options allow the display and editing of the animation sequence. The registered version of TheDraw adds Limiting and animation markers (as shown below). ┌──────────────────┐ │ Screen Redraw │ │ Change Character │ │ Erase Character │ │ │ │ Include Files │ │ Limiting │ │ marKer │ │ Movement Storage │ │ Rescan Animation │ │ Pause Animation │ └──────────────────┘ SCREEN REDRAW - Display the Entire Animation Sequence (ALT-Q) Displays the animation sequence as entered. The command is useful for seeing how your work is progressing. The speed of the redraw may be controlled by specifying a number between 0 (fastest) and 255 (slowest). CHANGE CHARACTER - Edit a Character in Animation Sequence (ALT-W) Allows the editing of a mistyped animation entry. Animation mode differs from the normal edit mode in that simply overtyping a character does not replace it. In animation mode, both entries are remembered - the incorrect character, plus the wanted one. This command permits you to edit something without adding unwanted characters. TheDraw v3.20 Pull Down Menu System 24 ERASE CHARACTER - Delete a Character from Animation Sequence (ALT-Z) Deletes characters from the animation sequence. As stated above in the CHANGE CHARACTER option, a character is not replaced or deleted in animation mode by overtyping. To erase something this command must be used. Only the top-most character (the one currently visible) is removed; anything under it is left intact. INCLUDE FILES - Ansi/Ascii Include Files (ALT-J,Include) Allows text files created by programs other than TheDraw to be inserted into Animation sequences. Particularly useful for Ansi Music, and often used sequences. LIMITING - Animation Sequence Editing (ALT-J,Limit) - Registered Limiting gives total control over the animation sequence, making changes anywhere trivial. Normally all changes and additions are done on the end of the animation sequence. By using limiting, you can move that point to anywhere in the sequence. Once the limit point has been set, TheDraw operates only up to that point. All deletions, additions and correcting are done where the limit is specified. Everything in the sequence above the limit is protected. MARKER - Animation Markers (ALT-J,marKer) - Registered Markers are used to "mark" different places in the animation sequence for later reference. Once set, markers can be used for quickly changing the animation limit position (see above) and viewing specific portions of the animation sequence. MOVEMENT STORAGE - Cursor Movement Storage (ALT-J,Movement) Controls whether or not cursor movement is stored in the animation sequence. Normally only characters specifically typed are recorded. With this option turned on however, movements of the cursor are also saved (for example, using the mouse or arrow keys). RESCAN ANIMATION - Animation Screen Rescaning (ALT-J,Rescan) Creates a new animation sequence using the current screen image. Any previous animation is lost (unless in animation limiting mode. See ALT-J description). TheDraw v3.20 Pull Down Menu System 25 PAUSE ANIMATION - Animation Pausing (ALT-J,Pause) Inserts either a keyboard or timed pause into the animation sequence. Gives the opportunity to sit and reflect upon a certain presentation. Note these pauses are truly functional only within TheDraw or THEPP (The Presentation Program). Pauses cannot be accurately saved to Ansi files. The COLOR Menu ---------------------------------------------------------------------- Use this menu to select edit colors. Options are available for setting normal edit foreground and background color, the default background color used for erasing areas, and "picking up" colors current used underneath the cursor. ┌──────────────┐ │ Fore/Back │ │ Default │ │ Under Cursor │ └──────────────┘ FORE/BACK - Change New Character Fore/Background Color (ALT-A) Displays a screen showing available colors. Simply select wanted color using mouse, arrow keys, or directly typing the number. See also CTRL-UP/DOWN. DEFAULT - Change Default Erase Background Color (ALT-D) Similar to above, except changes default color. This is used whenever TheDraw must erase an area, or it otherwise creates a "void" to be dealt with. UNDER CURSOR - Use Colors Currently Under Cursor (ALT-U) Changes new character fore/background color attributes to those under the edit cursor. Very useful for making quick updates and fixes. TheDraw v3.20 Pull Down Menu System 26 The TOGGLES Menu ---------------------------------------------------------------------- The Toggles menu contains settings for controlling how TheDraw operates. The settings affect things like line draw or sprite mode, animation mode toggling, character insert mode, and full screen editing. ┌────────────────┐ │ Draw Mode │ │ Sprite Mode │ │ Animation Mode │ │ Insert Mode │ │ Full Screen │ └────────────────┘ DRAW MODE - Line Draw Mode Toggle (ALT-M) Turns on/off line drawing mode. Line drawing is accomplished using characters from function key sets 1 to 4. In this mode, moving the cursor draws a line. Useful for creating abstract shapes quickly and easily. SPRITE MODE - Sprite Editing Toggle (ALT-E,Toggle) Turns on/off TheDraw Sprite Editing Mode. Please refer to ALT-E for more in depth discussion about Sprite mode. ANIMATION MODE - Animation Mode Toggle (ALT-J) Changes TheDraw from Normal to Animation mode and visa versa. When going from Normal to Animation mode, a list of available screen scanners are presented. See ALT-J below for more details. INSERT MODE - Character Insert Mode Toggle (INSERT) Turns on/off character insert mode. In insert mode, typing something bumps everything to the right to make room for the new character. FULL SCREEN - Full Screen Editing Toggle (CTRL-PRTSC) Toggles using the entire screen for editing. In full screen edit mode, the status line along with all indicators disappear. This makes the full 80 by 25 screen available for editing. TheDraw v3.20 Pull Down Menu System 27 T H E D R A W K E Y B O A R D C O M M A N D S _________________________________________________ ALT-A: CHANGE TEXT COLOR ATTRIBUTES This function allows you to change the current color attributes used by TheDraw. These attributes "color" any new characters placed on the screen. When you press ALT-A, the screen will change to a display of the available colors and the currently selected colors. The lower portion of the screen contains the two prompts: Please Select Foreground Color (0-31): Please Select Background Color (0-7): The cursor will be flashing immediately after the first prompt. You can now change the current foreground color by using the Up and Down arrow keys to select the wanted value, or by directly entering the number associated with one of the following foreground colors. Mouse users position the mouse on the wanted color and press a button. 0 Black 8 Dark Gray 1 Blue 9 Light Blue 2 Green 10 Light Green 3 Cyan 11 Light Cyan 4 Red 12 Light Red 5 Magenta 13 Light Magenta 6 Brown 14 Yellow 7 Light Gray 15 White Characters can be made to blink by selecting colors from the range 16 through 31. These match the above exactly, except they blink. After changing the foreground color (or if satisfied, not changing it) you can either proceed to the background colors by pressing [ENTER] or press [ESC] to return to the edit screen. Background colors are selected in a fashion similar to the foreground colors and may be any of the first eight (0 through 7) colors listed above. There are no background colors available that allow blinking. Pressing either [ENTER] or [ESC] at this point will return to the edit screen. Notes: It is possible to change the colors without using ALT-A. Please see the Ctrl-Arrow Key commands for more details. Monochrome screen users will find background colors generally useless except when set to light gray (7) and you are using a black foreground color of 0 or 16 (blinking black). TheDraw v3.20 TheDraw Command Functions 28 ALT-B: BLOCK ACTION COMMANDS The Block Action Commands provide many facilities for editing and making extensive changes to the current screen. The following options are available: o Move or Copy blocks of text. o Fill in areas with characters, colors or both. o Perform left, right or center text justification. o Draw boxes or outline text with lines quickly and easily. o Delete or simply Erase blocks of text. o Load a block of screen area from a file on disk. o Save just a piece of the current screen to disk. The Block Action Commands in TheDraw are one of the more useful utilities available. After pressing ALT-B, you will see the following prompt: Use [L]ast block or move to Upper-Left corner and press [SPACE]. You can either press [L] to use the last block specified or define a new block. To define a new block, the upper-left and lower-right corners must be specified. Use the arrow keys, PgUp, PgDn, Home or End keys on the keyboard to move the cursor to the wanted locations, then press [SPACE] after you reach each point. The current block is highlighted (colors inverted) to make it obvious. Once you define the upper-left corner of the block, moving above or to the left of it will not invert any text. TheDraw will stop the block marking if you press [SPACE] under this situation. Upon pressing [SPACE] the second time (with an inverted block) you will see the available block option commands. The items on the menu, and their significance are described on the following pages. ----- Mouse users may mark a block by pressing and holding the LEFT mouse button, moving the mouse to wanted block size, and releasing the button. Block option commands as described below will then appear. TheDraw v3.20 TheDraw Command Functions 29 COPY - Copy a Block Copies the marked block. Use the arrow keys, PgUp, PgDn, Home or End on the keyboard to move the block copy around. Available sub- commands are: pagE - Change to a different page layer screen. With this option you can choose to stamp (see below) copies of the block on other layers. A small window appears with a prompt for the new page layer. Enter a number or press [ESC] to abort. Toggle - Toggles between single layer and sprite editing modes (see ALT-E for discussion on sprite editing). In sprite mode, any text on a higher numbered page layer will appear "under" any text on the current page. Stamp - Makes a copy of the current block at the current position. Additional copies can be done as many times as wished. Under - Toggles between moving the block "above" or "under" the current page layer. The block copy starts in above mode. In above mode the entire block is visible, no matter where it is moved. In under mode, the block appears UNDER any other text on the current page layer. It will only show through the black spaces on the current layer. Note: Under mode also allows an interesting effect. If you are sprite editing (see ALT-E command) the block will appear to move -between- the current layer and the layers below it. [ENTER] Saves all changes made to all layers. [ESC] Aborts and removes all changes made to all layers. MOVE - Move a Block Moving a block operates identically to copying a block (see above). The only difference is the block is "cut" out from the current screen, leaving a hole behind. This hole is filled with spaces and the current default background color (see ALT-D regarding default background color). All sub-commands are identical to the block copy described above. TheDraw v3.20 TheDraw Command Functions 30 FILL - Fill a Block Fills the marked block based on a specified sub-command. The available options are listed below: Attribute - Changes both foreground and background color attributes to current values shown in status line. Fore - Changes just the foreground color attributes to current values shown in status line. bacK - Changes just the background color attributes to current values shown in status line (is this sounding familiar by now?) Use - Changes both foreground and background color attributes to those under the CURSOR when you first pressed ALT-B. This is not the upper-left block corner, but the position on the screen the cursor was sitting when block commands were first selected. Character - Prompts for a keyboard character or special function set symbol (see ALT-F command). Solid spaces can be used by pressing Shift-Space. The block is then overwritten using whatever was selected. The color attributes at any given position are not changed, just the character at that position. Both - Combines both the Attribute and Character fill operations described above. A character is prompted for, then everything in the block is overwritten using that character with the current color attributes from the status line. These commands offer much flexibility; however, nothing will satisfy everyone. For this reason, the "last block" option was added. To perform multiple fill operations on a given block is now done quickly and easily. Note: In animation mode, the Attribute, Fore, bacK, and Use options actually change characters in the animation sequence (no new characters are added). Use of the Character or Both option in Animator mode however WILL add additional characters to the animation sequence. TheDraw v3.20 TheDraw Command Functions 31 TEXT - Block Text Operations Performs various text operations on the specified block. Available sub-commands are: Box - Draws a box using the current function set. The box border is defined by the edges of the block area. The contents of the box are left unchanged, however anything where the box lines are actually drawn will be overwritten. Outline - Operates similar to the Box command, except the contents of the block are examined first. The box border will be adjusted to just accommodate all words either fully or partially contained by the block area. For instance, assume you just had one character in the center of the edit screen. You then mark the entire screen as a block, and select text outline. The result would only be a small box around the character. Going the other way, assume you a long word (no spaces) and only block marked the center character. Text Outline would then expand the edges of the block to accommodate the full size of the word. Note: the expansion is only done for words INITIALLY part of the block. Any words the block expansion happens to go over are ignored, and not considered by Text Outline. Center - Text contained or partially contained by the block is centered. The way this is done is similar to the text Outline described above. Each line of characters considered is expanded to just enclose all words. The string of words is then centered on the position of the block. Left - Text contained or partially contained is moved to the left edge of the block. Block expansion is used so words are not split apart. Right - Identical to Left except contained or partially contained text is moved to the right edge of the block using Block expansion. These commands are useful making menu displays or short memos or letters, etc... TheDraw v3.20 TheDraw Command Functions 32 DELETE - Delete a Block This command is fairly intuitive. The block is completely removed. Anything on the edit screen to the right of the block is shift over to fill in the space. The area previously occupied by the shifted text is filled with spaces using the default background color (see the ALT-D command regarding default background colors). ERASE - Erase a Block Erases the block, without changing anything other portion of the edit screen. The block is erased using spaces and the default background color (see above). The following commands are available only in normal (non-animation) screen edit mode: LOAD - Load a Block Imports a block of data from another screen saved on disk. The current image is saved, then you are prompted for the import filespec to load (see ALT-L for details on loading files). The import image is then loaded onto the screen, and an inverted area of the defined block size appears. Move this inverted area using arrow keys, PgUp, PgDn, Home or End to the wanted portion. Press [ENTER] to save a copy of the inverted area appear in the original edit screen. The rest of the import image is discarded. SAVE - Save a Block Operates almost identically to the normal save screen command (see ALT-S for information on saving edit screens). The difference being that what is saved is restricted to the defined block. In addition, TheDraw format files for blocks are currently not available. The following command is available only in animation edit mode: RESCAN - Rescan a Block Operates just like the ALT-J animator rescan option, except only the marked block is rescanned. The marked block area is first erased from the animation sequence, then the block is rescanned and added onto the end of sequence. TheDraw v3.20 TheDraw Command Functions 33 ALT-C: CLEAR CURRENT SCREEN The operation of this command should be apparent. Once selected, the following prompt appears: Do you want to CLEAR this Page or All Page Layers? (Yes/No/All) Selecting [Y]es or pressing [ENTER] will clear the current page layer and nothing else. Selecting [N]o or pressing [ESC] will abort the command. Selecting [A]ll will clear ALL page layers. You are prompted to verify this request before continuing. Useful if you quickly need a completely clean slate. The clearing of a given page layer is done by using spaces and the default background color (see ALT-D below). ALT-D: SET DEFAULT BACKGROUND COLOR The default background color is used whenever TheDraw must erase a portion of the screen. Examples of commands where this is used are: o Clear Current Screen. o Block Delete, Erase, and Move. o Text Operations which move words. o Use of the Backspace or Delete keys to remove characters. o Inserting or Deleting of Lines. All these commands "clear" an area of the screen in one way or another. TheDraw clears the area using spaces and the default background color specified using this command. When you select ALT-D, the screen changes to a display of available colors and the current default background color. In the lower portion of the screen is the prompt: Please Select Background Color (0-7): The cursor will be flashing after this prompt. You can now change the default background color by using the Up and Down arrow keys to select the wanted value, or by directly entering the number associated with a color (see ALT-A for available colors). Mouse users simply position the mouse on the wanted color and press a button. Press [ENTER] or [ESC] to return to the edit screen. TheDraw v3.20 TheDraw Command Functions 34 ALT-E: EXCHANGE EDIT SCREENS The exchange edit screen command allows you to select a different page layer for editing. Up to eight simultaneous layers can be used at once, in either normal or animation modes. With this facility, you can load several images, copy/exchange different parts and do much more. After pressing ALT-E, the following prompt appears: Display Page Layer (1-8), Toggle Single/Layers, or [ESC]? The number of available layers (8 here) will vary depending on how TheDraw has been configured. To select a different page layer, simply press the number. The second option, [T]oggle Single/Layers, is to toggle the sprite editing facility of TheDraw. Sprite mode is indicated by with word "Page" or "Anim" appearing in capital letters on the status line (ie: PAGE). Sprite editing allows you to see everything "underneath" the current page layer. Imagine several sheets of glass, stacked on top of one another. If you look down from the top-most sheet, you can see anything placed on a piece of glass lower down. The sprite editing mode of TheDraw is akin to the layers of glass described above. In this case, layer one is the top-most sheet of glass. Page layer eight (8) is the bottom-most sheet of glass. ie: ┌────────┐ .│ . │ . │ . │ Bottom-Most Layer ┌────────┐ 8│ ┌─┴──────┐ │─────┘ ┌─┴──────┐ │ │ . │ │ │3│ . Top-Most Layer │ │2├─┘ │ 1├─┘ └────────┘ Naturally, an object or character closer to the top will cover anything under it. In TheDraw, anything other than a non-solid black space will conceal the contents of a lower layer. Another useful feature about sprite editing is only the current page layer may be changed. Nothing you do will alter a layer below (short of clearing all layers), even though you can see its contents. The current layer can be moved around, have lines deleted, etc... Anything lower down is protected unless you specifically change to that page layer for editing. TheDraw v3.20 TheDraw Command Functions 35 A question that now comes to mind, is what can be done with this facility? Answer: Plenty. Imagine you have a screen made of several distinct parts, say a backdrop with figures on it. Now a figure must be moved to make room for something else. Unless "block" shaped, the block move command (ALT-B) is tedious to use. For something tree shaped, an easier way is desired. Using sprite editing each figure could have its own layer, with the backdrop placed on the bottom-most page. To move a figure, you merely switch to its layer, and use the global screen move command (ALT-G). Nothing could be simpler. To see the result of your change, switch back to the top-most layer. Menu making can be made easier using sprites also. Put together the basic outline (lines, boxes, etc...) on one page layer, then switch to a higher up layer for the text. If you do not like the initial text, erasing it will not harm the outline. There are endless more possibilities waiting to be discovered. ALT-F: VIEW FUNCTION KEY SETS This command simply shows a display of the 150 special characters supported by TheDraw. These characters are stored in fifteen separate "function key sets". The current set is displayed on the TheDraw status line. Selecting function key sets is divided between two commands. To use function key sets 1 to 10, press ALT followed by a function key 1 to 10. To use function key sets 11 to 15, press CTRL followed by a function key 1 to 5. ie: ALT-F7 will select function key set 7 CTRL-F4 will select function key set 14 The actual characters are accessed using the function keys by themselves. If function key set 7 was selected, pressing [F2] would display the second character in that set (a smiley face). Note: Appendix C contains a list of all special characters supported by the IBM-PC (tm) extended character set in numeric order. To access these characters -without- using the function key sets, press and hold down the ALT key. Now using the numeric keypad on the side of the keyboard, type in the number associated with the wanted character. Once done, release the ALT key. The character will then appear. ie: press and hold ALT. Now type 65 on the numeric keypad, and release ALT. The letter "A" will appear. TheDraw v3.20 TheDraw Command Functions 36 ALT-G: GLOBAL COMMANDS The global commands offer many facilities for doing "global" changes to the entire screens. All of these commands could be duplicated with block operations; they exist for convenience. The following selections are available: o Copy the current screen to another page layer. o Move/Rotate the current screen around its borders. o Globally fill the screen with colors and/or characters. o Perform text operations globally on the text. After pressing ALT-G the available commands are listed. The items on the menu are described below: COPY - Copy Screen The command first prompts for the destination page. The current screen is then copied to the specified page layer. In animation mode this has the effect of first deleting everything on the destination layer, then copying from top to bottom the current screen to it. MOVE - Move/Rotate Screen Moves the entire screen around its borders. Use the arrows keys to rotate the screen. Press [ENTER] when satisfied or [ESC] to leave the screen as it was. ie: moving the screen upwards will "rotate" the line at the top of the screen down to the bottom of the screen. TheDraw v3.20 TheDraw Command Functions 37 FILL - Fill Screen Fills the entire screen based on a specified sub-command. The available options are listed below (these are identical to the block fill commands): Attribute - Changes both foreground and background color attributes to current values shown in status line. Fore - Changes just the foreground color attributes to current values shown in status line. bacK - Changes just the background color attributes to current values shown in status line. Use - Changes both foreground and background color attributes to those under the CURSOR when you first pressed ALT-G. This is not the upper-left screen corner, but the position on the screen the cursor was sitting when global commands were selected. Character - Prompts for a keyboard character or special function set symbol (see ALT-F command). Solid spaces can be used by pressing Shift-Space. The screen is then overwritten using whatever was selected. The color attributes at any given position are not changed, just the character at that position. Both - Combines both the Attribute and Character fill operations described above. A character is prompted for, then everything on the screen is overwritten using that character with the current color attributes from the status line. These commands are identical to the block action fill commands. In animation mode, the Attribute, Fore, bacK, and Use options actually change characters in the animation sequence (no new characters are added). Use of the Character or Both option in Animator mode however WILL add additional characters to the animation sequence (2000 characters exactly). TheDraw v3.20 TheDraw Command Functions 38 TEXT - Global Text Operations Performs various text operations on the screen. Available sub- commands are: Box - Draws a box using the current function set. The box border will be the defined by the edges of the screen. The inside of the box is left unchanged, however anything where the box lines are actually drawn will be overwritten. Outline - Operates similar to the Box command, however the contents of the block are examined first. The box border will be adjusted to just accommodate all words contained by the screen. For instance, assume you just had one character in the center of the edit screen. The result of using global text outline would only be a small box around the character. Center - Text in the screen is centered. The way this is done is similar to the text Outline described above. Each line of characters considered is reduced to just enclose all words. The string of words is then centered in the screen. Left - Text is moved to the left edge of the screen. Right - Identical to Left except text is moved to the right edge of the screen. These commands operate similar to the block action text commands. ALT-H: DISPLAY HELP INFORMATION The help screens provide a quick reminder for the various commands supported by TheDraw. The two screens briefly describe most available functions. The registered version of TheDraw supports context sensitive pop-up help for the ENTIRE program. Typing ALT-H at any position will display specific help on what you are doing. Try it, you'll like it! TheDraw v3.20 TheDraw Command Functions 39 ALT-I: INSERT A LINE Inserts a line at the current position. The current line and all those below it are shifted down. The bottom line is lost. This command is not reversible, so use with care. ALT-J: ANIMATOR OPTIONS The Animator Options command operates differently depending on which mode you are currently in (Normal or Animator). ALT-J FROM NORMAL MODE ______________________________________________________________________ When in Normal mode, selecting ALT-J will put TheDraw into animation mode. To convert the existing normal screen images (static images) to animation entries, a "scan method" must be specified. The particular scan method used tells TheDraw how to read your static images for display. Ten different scan methods are available: TOP - Scan Top to Bottom The static page layers are all scanned from their upper-left to lower-right corners. The scan goes across the screen (left to right). The next line down is then scanned, and so on. BOTTOM - Scan Bottom to Top Exact opposite of TOP. The static page layers are scanned from their lower-right to upper-left corners. The scans starts on the bottom line, and goes across the screen (right to left). The next line up is then scanned, and so on. LEFT - Scan Left to Right Similar to TOP, except the scan goes down the screen (top to bottom). The next column over is then scanned, and so on. RIGHT - Scan Right to Left Exact opposite of LEFT, and similar to BOTTOM. Scan goes up the screen (bottom to top), starting the right-most column. The next column to the left is then scanned, and so on. TheDraw v3.20 TheDraw Command Functions 40 SCRAMBLE - Random Scramble Scan Each static page layer is scanned in a completely random order. ANGLE - Angle Scan Scans each static page layer from upper-left to lower-right corners, using a backward angle approach. ie: scan character then move down to next line and backup one position. AAAAAAAAAA BBBBBBBBB CCCCCCCC DDDDDDD etc... GATE - Gated Scan Alternating lines scan from opposite sides of the screen forwards and backwards going across. The first line will scan left to right going across the screen. The second line scans right to left across the screen. The third line scans as the first, etc... All lines are processed at once, so the screen appears "gated". PYRAMID - Pyramid Scan Scans in a "pyramid" shape, starting from bottom center of screen. . .D. cDCD. tDCBCD. eDCBABCD. SQUARES - Squares or Spiral Scan Scans static screen images using squares. The border of the screen is first scanned (progressing clockwise). The next smaller square is then scanned, and so. Produces a spiral effect. WIGGLE - Wiggle Scan Similar to GATE, except only one line is processed at a time. Produces a snaking line appearance starting from the top of the screen. Scan first goes across screen, then returns on next. The cycle is then repeated. If you have ideas for more animation scanners, please send them! TheDraw v3.20 TheDraw Command Functions 41 Once the animation scan is completed, then screen will be cleared and redrawn. At this point TheDraw will operate as normal, except everything is sequenced by the animation system. Please refer to the section "The Animation System" for more details on its use. ALT-J FROM ANIMATOR MODE ______________________________________________________________________ Once in animator mode, selecting ALT-J presents several facilities for managing the animation system. The following commands are available: o Specify Animation Include Files o Toggle storing of cursor movements o Convert animation screens to normal mode static screen images. o Rescan current animation screens. o Enter a pause into the animation sequence. The registered version of TheDraw also supports: o Adjust Animation Limiting o Specify Animation Markers Each item on the menu is described below: INCLUDE - Specify Animation Include File When creating an ANSI file, TheDraw allows text from other files to be "included" in the one it creates. Ten different files can be included in any given sequence at any given point in the sequence. When TheDraw includes another file, it copies everything from the include file to the new output file TheDraw is making. Once the output Ansi file is created, the include file is not needed again. The include file need only be present when TheDraw is actually copying text from it. Include files are only read when TheDraw actually saves a file. They are ignored by ALT-Q. If you wish to see what everything looks like before saving, use the View option described below. TheDraw v3.20 TheDraw Command Functions 42 Upon choosing the INCLUDE option, a window will appear on the screen. All currently defined include files will be listed, along with their position in the animation sequence. The following sub- commands are available: SET - Sets an include file at the current animation position. In the shareware version of TheDraw, this will always be the end of the current animation sequence. In the registered version, this is the current animation limit position. This allows include files to be easily specified "after the fact", anywhere in the animation sequence (see Limit below). CLEAR - Erases the include file entry you specify. No verify is done before the entry is deleted, so be warned. VIEW - Displays the entire animation sequence, with all specified include files. Very useful for testing the appearance of things. Press [ESC] once when done editing the include files. All changes are saved. Animation include files are especially useful for including so called "Ansi Music" sequences into a TheDraw image. Ansi Music is an extension to the ANSI.SYS driver found is certain modem communication programs. Please note that TheDraw cannot generate Ansi Music source sequences. LIMIT - Specify Animation Limit (registered version only) The animation limit facility of TheDraw provides for a powerful animation editing system. You can easily correct mistakes, insert, delete or do anything else in the MIDDLE of any animation sequence. To make it work, you specify a point for TheDraw to temporarily stop displaying the animation sequence. For example, assume you had a sequence with 5000 entries. You could limit it to 2000, correct a spelling mistake, then quickly set the limit back to 5000. When limiting is on, TheDraw operates exactly as before, except everything above the limit is held out of the way. TheDraw v3.20 TheDraw Command Functions 43 Upon choosing the LIMIT option, you can specify the animation limit position using the following keys: Up/Down Arrows Advance/Backup limit by one position. PgUp/PgDn Advance/Backup limit by 100 positions. Home Go to start of sequence (position = 0). End Go to end of sequence (all entries). marKer Move to the position of an animation marker. Selecting this command displays a window of all currently set animation markers. After choosing a marker, the animation limit moves to the position of the marker. Assuming you have set markers in strategic places, this allows you to quickly bounce around an animation sequence looking for a particular spot. Press [ENTER] to save your changes to the animation limit. Pressing [ESC] resets the animation limit position to its entry value. MARKER - Specify Animation Markers (registered version only) Markers are used to "mark" different places in the animation sequence for later reference. Once set, markers can be used for changing the animation limit position (see above) and viewing just portions of the animation sequence. They can be useful in locating things forgotten or set aside until later, editing images a page at a time, etc... Upon choosing the MARKER option, a window will appear on the screen. All currently defined markers are listed, along with their position in the animation sequence. The following sub-commands are available: SET - Sets a marker at the current animation limit position. This allows markers to be easily specified anywhere in the animation sequence. You are first be prompted for which marker to change. If the marker is already set, it will be erased before continuing. After you specify a marker, you can then enter a comment (32 characters). CLEAR - Erases the marker you specify. No verify is done before the entry is deleted, so be warned. VIEW - Displays the animation sequence, up to a specified marker. Useful for reminding yourself of what happens early in a 16000 entry animation sequence. Press [ESC] once done editing markers. All changes are saved. TheDraw v3.20 TheDraw Command Functions 44 MOVEMENT - Toggle Storage of Cursor Movements Toggles whether or not TheDraw stores actual movements of the cursor. Normally only characters actually typed are recorded; however, if the cursor movement toggle is on then all movements of the cursor are also stored. Cursor movements are being stored whenever the ANIM symbol in the status line is flashing. If you are still in doubt, watch the animation entry count. It will increase every time you move the cursor. NORMAL - Convert to Normal Edit Mode. Converts what appears on the screen to normal mode images. All animation is erased after executing this command. You are first prompted to verify before continuing. In the registered version, anything not displayed because of animation limiting is lost. Only what appears exactly on the screen when you select this command is converted to normal mode images. RESCAN - Rescan the Screens Selecting this command prompts for an animation scan method as described above in the ALT-J FROM NORMAL MODE section. Everything in the animation sequence is first erased, then the images on the screens are rescanned. In the registered version, any animation sequence not displayed because of animation limiting is NOT lost. It will still be available after this operation is done. This differs from the above sub-option and allows you to go back and rebuild something which did not cut it the first time. TheDraw v3.20 TheDraw Command Functions 45 PAUSE - Animation Pausing Allows the entering of pauses into the animation sequence. With this command it is possible to have TheDraw pause for a key or wait a specified number of seconds anywhere while displaying an animation sequence. This can be very useful in presentations. After selecting PAUSE, the following sub-commands are available: TIME_PAUSE Creates a pause for a specified number of seconds (the pause can be aborted by pressing any key when actually displayed). You are prompted for the number of seconds to delay. KEY_ONLY_PAUSE Creates a pause for a key to be pressed. CLEAR Erases pauses from the animation sequence. TheDraw searches backwards from the current animation position for a Pause. If one is found, you can DELETE, VIEW up to this pause, or scan for the NEXT pause before this one. Press [ESC] to abort clearing a pause. Pauses are observed whenever you redraw the animation sequence with ALT-Q. When you save an ANSI file, it is not possible to produce exactly equivalent pausing (pauses for a key are impossible). For this reason, a small separate presentation program (THEPP) is included with registered copies of TheDraw. This program duplicates the operation of the ALT-Q command, and uses THEDRAW format data files. See section entitled "The Presentation Program" for information on using THEPP. ALT-K: DELETE A FILE Deletes a specified file from disk. Use this option to free up disk space when the need arises. The directory file selector (see ALT-L below) displays everything in the current directory. Use the arrow keys to select a file to delete, or simply type in the filename at the bottom of the screen. Press [ENTER] to select the file. TheDraw will then check for the file. If it exists, you are prompted to verify before continuing. This is your last change before you delete something you might regret later. TheDraw v3.20 TheDraw Command Functions 46 ALT-L: LOAD SCREEN FROM DISK This command allows you to load any ANSI text, ANSI Animation, ASCII text, BINARY dump, Basic BSAVE or THEDRAW format file. You are prompted to continue if the current screen image has not been saved. The directory file selector next displays all files in the current directory for convenience. At this point you can use the arrow keys and PgUp/PgDn keys to select a file or simply type in the wanted filename at the bottom of the screen. Press [ENTER] to select the file. If there are many files in the directory, you may specify a filename wildcard to specify a small sub-set of the available files. Wildcards operate identically to those found in Dos. Please refer to your Dos manual for additional information. Wildcards are normally temporary, and are not maintained. They can be made "sticky" however by use of the Setup utility. If you type in the filename, a file extension of ".ANS" is assumed unless otherwise specified. The following file types require the specified extensions for TheDRaw to be able to load them: Binary Dump .BIN Basic BSAVE .BSV TheDraw Format .TD TheDraw COM File .COM Any file without one of the above extensions is assumed to be an ASCII or ANSI file. Assembler, Pascal, and C format files cannot be reloaded, except as Ascii text. You must keep another copy of those screens safely somewhere in one of the above loadable formats. Binary and TheDraw format files load full screen 25 line images. If you are not in full screen edit mode, those lines hidden by the status information are stored. Binary files might be only stored as blocks (see block save under ALT-B). To load a binary block dump, TheDraw must know the width of the block. If a binary block is detected, TheDraw will prompt for this value. The BSave and COM file formats load similar to the above. The might contain a full screen image or just a small screen block. Block loads only overwrite that portion of the screen. When loading Ansi or Ascii, only the first 24 displayed lines are stored. Any extra are discarded. Do not be alarmed by Ansi files which can be hundreds (or possibly thousands) of lines long. So long as the cursor never goes below line 24, everything will load properly. TheDraw v3.20 TheDraw Command Functions 47 Ansi animation is automatically detected by TheDraw using the following advanced system: If the cursor suddenly moves to a place it normally could never go, this is an animator file. A complex algorithm, no? Please note the above mentioned file extensions may be personalized by using the Setup utility if so wished. ALT-M: SELECT DRAW MODE TheDraw supports the "drawing" of lines. This is easily done using the arrow keys while in Draw mode. The characters used in the lines are those normally available via the function keys from the current function key set. Only the first four sets of characters contain lines. If a function key set without lines is selected, the first set (single lines) is used. Draw mode is indicated by the word "Draw" at the bottom of the screen. In draw mode, everything operates without change. Typed characters still appear. The only change is that using the arrow keys makes a line appear in the direction moved. ALT-N: RULER The Ruler command places a pair of intersecting lines on the screen. The point of intersection represents the position of the cursor. The ruler can be moved using the arrow keys, PgUp, PgDn, Home and End. Press [ENTER] to save the new cursor location, or press [ESC] to return to the initial cursor position. Use this command to help line up rows or columns of text or figures. ALT-O: CHANGE DRIVE/SUB DIRECTORY This command requires the use of DOS 2.0 or higher to operate. This command allows you to change the default directory or path (displayed when loading or viewing a file). All sub-directories of the current path are displayed for you. A new directory can be selected by using the arrows keys or typing in the pathname. Press [ENTER] to change to that directory. Note that the details of sub-directories are not covered here. Please refer to your dos manual for that. For example, if you were on drive C in a sub-directory named GAMES, you could switch to the subdirectory UTILITY of drive D by entering "D:\UTILITY". You could then get back to the directory GAMES by simply entering "C:" (no backslash). TheDraw v3.20 TheDraw Command Functions 48 Alt-P: PAINT/FILL COMMANDS This command allows enclosed areas to be easily filled with characters and/or attributes. An enclosed area is made by using lines (from function key sets 1-4) or using the Draw command (see ALT-M). To use this command, position the cursor inside the area then press ALT-P. The following sub-commands are available: ATTRIBUTE - Changes all foreground and background color attributes within the enclosed area to those values shown in the status line. CHARACTER - Prompts for a keyboard character or special function set symbol (see ALT-F command). Solid spaces can be used by pressing Shift-Space. All enclosed characters are then overwritten using whatever was specified. No color attributes are changed, just actual character symbols. BOTH - Combines both the Attribute and Character paint operations above. A character is prompted for, then everything in the area is overwritten using that character with the current color attributes from the status line. In animation mode, the Character and Both options add new entries to the animation sequence; nothing is deleted. The Attribute command however only changes the color attributes of characters already in the animation sequence. No new entries are added. ALT-Q: REDRAW SCREEN (available in animation mode only) This command redraws the animation sequence on the screen. With this you can see how your work is developing. You are prompted for the display speed to redraw at. Available speeds are from 0 (fastest) to 255 (crawl). A value of about 40 is generally a good speed to view at. Be warned that 255 literally is a crawl speed, displaying between two and four characters per second (standard PC/XT). A slow redraw can be broken out of by pressing any key. TheDraw v3.20 TheDraw Command Functions 49 ALT-R: RESTORE CURRENT LINE Restores the current line to original contents if you make a mistake while entering in text. Removes all changes to the line made by the user. Once you move to a new line however, all changes are permanent. ALT-S: SAVE SCREEN TO DISK The Save Screen command offers many formats for saving the entire current screen. The available formats are: Ansi, Ascii, Asm, Binary, BSave, Com, Pascal, C and TheDraw. Please note that all color attributes are lost in an Ascii file. All other formats store the complete screen with color information (unless you specify otherwise). The entire screen is saved when using this command. If you do not require the entire 80x25 screen, use a block save (see ALT-B). These can be more effective at times. You are first prompted for which storage format to use. In animation mode, only ANSI and THEDRAW formats are available. The items on the menu are discussed below: ANSI - Ansi text file You are first asked what initial screen preparation you want before the image is displayed. Options are: CLEAR - Clears the screen HOME - Move cursor to upper-left corner of screen NONE - Leave screen and cursor position as is. The next prompt is for the maximum length of each line in the saved file. TheDraw is capable of producing over 1300 characters per screen line (if every character had a differing color combination). Some applications and programs (ie: other text editors) cannot handle so many characters per line. This option limits the output line length sacrificing time to display the image. If length is no problem, specify [N]one for the most efficient file. Lastly, you are prompted for the Ansi display speed (a number from 0 to 50). The operation is similar to the ALT-Q animator redraw screen function. Things are slowed down by adding redundant codes after everything that is displayed. A value of 50 is approximately equal to an ALT-Q speed of 255 (extremely slow). Experimentation will find the most appropriate speed for your needs. TheDraw v3.20 TheDraw Command Functions 50 ASCII - Ascii Text (no colors) If you select ASCII, you are prompted if you really want a non- color image made before continuing. The Ascii file produced is similar to any file produced by a normal text editor (ie: Turbo Pascal or Sidekick editor). ASM - Assembly Language ASM produces a list of DB data statements for use by assembly language programmers. Addition sub-options are available to specify the assembler data format. You can specify to Crunch, output only Ascii characters, or dump a normal file. Crunching uses a custom method of compressing color changes and strings of identical characters to make the smallest possible file. To display a crunched file you must use the uncruncher routine included separately with TheDraw (UNCRUNCH.ASM). This file has comments explaining its use. The Ascii format saves all characters on the screen. No color attribute information is stored however. The normal file is a 4000 byte binary dump of the screen, converted to an assembler/compiler compatible format. BINARY - Binary Screen Dump Produces a straight 4000 byte dump of the video screen. This data format is generic. It is useful for many things, such as loading screen images directly to video ram, etc... BSAVE - Basic BSave Screen Dump This file is identical to a binary screen dump, except loading codes for Basic are placed at the front. These files can be loaded from basic with: DEF SEG = &HB800 : BLOAD"filespec.BSV",0 If you have a monochrome monitor, replace the B800 with B000 in the above line. TheDraw v3.20 TheDraw Command Functions 51 COM - Dos Executable COM Files. Produces a truly separate program that you may "run" from Dos by simply typing in the program name. COM files are useful in batch files and the like for -fast- displaying. If you save only a screen block (via ALT-B), the COM file displays only that block on the screen without changing anything else. You could conceivably generate a "layering" windows effect if you so desired. PASCAL - Turbo Pascal Compatible Screen Dump This operates the same as the ASM option described above, except the output is in a Turbo Pascal compatible CONST structure. See Appendix B for the section entitled "Programmers Programming Tips". To use the Crunched file format, use the file UNCRUNCH.PAS. C - Modern C Formatted Compatible Screen Dump (Turbo C) Again, this operates the same as the ASM option. The format is for the new "modern C" string continuation structure. The crunched C format may be displayed using code in the two files UNCRUN_N.OBJ and UNCRUN_F.OBJ. The header file UNCRUNCH.H contains instructions on their proper usage. THEDRAW - TheDraw Setup Save This format saves everything about the current configuration of TheDraw. In normal edit mode, all occupied page layers are saved. In animation mode, the animation sequence is dumped to disk. All other parameters are saved also (ie: current colors, tab line, cursor position, current page layer, etc...). The TheDraw format file also has the benefit of being the fastest way to loading and retrieve screen images - Eight page layers or 16000 animation entries take only seconds to load. TheDraw v3.20 TheDraw Command Functions 52 Following the above preliminary prompts, you are prompted for a filename. If the file already exists, you are prompted to verify the save. If you do not specify a filename extension, TheDraw assumes the following: .ANS ANSI compatible files .ASC ASCII text files .ASM Assembler files .BIN Binary dumps .BSV Bsave files .PAS Pascal files .H C files. .TD TheDraw format files. A file without an extension can be specified by placing a period as the last character of the filename (ie: TESTFILE. ). After entry of a valid filename, the screen is saved to disk. For suggestions on using the screen files created by TheDraw see Appendix B. ALT-T: TAB SETUP This command allows you to set tabs in the editor (positions where the [TAB] key stops). Initially the positions are at every tenth column. Available sub-commands are: SET - Set a new tab position. Move the cursor to the wanted position then press 'S'. CLEAR - Clears tab at current cursor position RESET - Resets tab line to initial settings (every ten spaces). ERASE - Delete all current tab setting for a clean slate. INCREMENT - Prompts for a step size. From the current cursor position, every nth location is then set. This allows you to quickly specify, say every fourth position if your need requires it. Press [ESC] to leave the tab set command. ALT-U: USE COLORS UNDER CURSOR Changes current status line colors to those currently under the cursor. This provides a fast method to change to colors already displayed on the screen. TheDraw v3.20 TheDraw Command Functions 53 ALT-V: VIEW A SCREEN This command allows you to look at a previously saved image on disk. The current page layer is not altered by using this command. You might use this in conjunction with the block load/import function (see ALT-B). Viewing a screen is done similar to loading (see ALT-L) except the loaded image is not remembered. Once the image is fully displayed, a window appears with instructions. Press [ENTER] to exit view mode. Pressing any other key will make the window disappear to facilitate viewing. After about 30 seconds the window will reappear to remind you about view mode (in case you leave the computer and then return). ALT-W: EDIT CHARACTER (available in animation mode only) Allows the editing of a mistyped animation entry. This command exists because simply overwriting an incorrect character does not delete it. In animation mode, both entries are remembered - the incorrect character, plus the wanted one. Upon redisplaying the animation sequence (see ALT-Q), both characters would be seen (the former for only a millisecond perhaps, but it would appear). The ALT-Z command could be used to delete just the incorrect entry. The wanted character could then be entered. This will indeed work perfectly well, and some people may prefer using this method; however, to quickly change the entry ALT-W is more convenient. After pressing Alt-W you are prompted to type a new character. The current position will be flickering. All color changing commands are available (ALT-A and the Ctrl-Arrow keys) while editing. ALT-X: EXIT THEDRAW Prompts if you wish to exit TheDraw or execute a shell to DOS. Responding Yes exits the program. No cancels the command. Shell also exits to Dos, however TheDraw remains in memory. All screen page layers and animation entries are retained. Typing the command "EXIT" at the Dos prompt will return control to TheDraw. TheDraw v3.20 TheDraw Command Functions 54 ALT-Y: DELETE CURRENT LINE Deletes the current line on the screen. All lines below the current line are shifted up one position. The bottom line is cleared using spaces and the default background color. This command is not reversible, so use it carefully. ALT-Z: ERASE CURSOR CHARACTER (available in animation mode only) Erases the top-most character from the animation sequence at the current cursor position. Only the last character typed at the cursor position is deleted, everything typed before is unchanged. TheDraw v3.20 TheDraw Command Functions 55 ALT-= TOGGLE MACRO LEARN MODE (registered version only) Activates the macro learning mode of TheDrawR. You are prompted for which macro key to program (0-9). After specifying the macro, TheDraw remembers everything you type. This is somewhat akin to animation mode; however, macro learn mode literally remembers everything. All editing commands performed, any characters typed, etc... Up to 512 characters will be recorded. Once satisfied with the macro, type ALT-= again to save the macro. To use the macro, press ALT followed by a number key 0 through 9 (NOT the ones on the keypad). ALTERNATE COLOR CHANGE OPTIONS For the experienced user, TheDraw provides a more convenient way of adjusting the current status line colors. Pressing Ctrl-Up increments the current foreground color number (found in ALT-A) and Ctrl-Down decrements it. These two key combinations do not always work reliably on all computers (a Bios flaw exists). To get around this, TheDraw incorporates a special keyboard driver to handle these two keys. If they do not work on your machine run the SETUP utility and use "Keyboard Customize" to configure TheDraw to your keyboard. Pressing Ctrl-Right increments the current background color number; Ctrl-Left decrements it. SHIFT-SPACE: SOLID SPACE CHARACTER As stated elsewhere in this documentation, the sprite mode of TheDraw makes other page layers appear through "black spaces" on the current page layer. This can sometimes be convenient and sometimes not. There are instances when you want to have a non-transparent black space on the screen. The Solid Space performs this function (non-transparent black space). Moving the cursor onto a solid space will cause the background color to flicker as an indicator. A Solid space is nothing more than a character #255 (which is a blank IBM extended character). TheDraw v3.20 TheDraw Command Functions 56 CTRL-PRTSC: FULL SCREEN MODE TOGGLE This command toggles screen usage in TheDraw between 23 lines (regular) and 25 lines (full-screen). In full-Screen mode the status line disappears so you can fully use the screen. TheDraw also makes heavy use of pop up windows for prompts and messages in this mode. While useful, it can be awkward since YOU must remember where you are at all times. For instance, block marking and etc... It is easy to become confused unless you are careful. If all else fails, hit ESC a few times to abort the current command. Some people may prefer this mode which is fine. Nothing forces you to use either screen size for anything. Ctrl-PrtSc only operates from command mode. It is not available under any sub commands (such as Block, Global, etc...). There are no restrictions on full screen use in animation modes. TheDraw now supports saving text on -most- of line 25 when using Ansi files. Previously this line was totally ignored. Although the situation is improved, TheDraw still prevents the saving of anything in the very lower-right corner of the screen (column 80, line 25). Any character placed there causes an unwanted, uncontrollable, totally disastrous (well... close enough) screen scroll by Dos. TheDraw v3.20 TheDraw Command Functions 57 THE ANIMATION SYSTEM ____________________ WHAT IS ANSI ANIMATION? ______________________________________________________________________ The animation system of TheDraw allows the user to create screens with movement, adding excitement to your presentations. In animation mode, TheDraw stores every keystroke typed that places a character on the screen. This creates what is called the animation sequence. When the animation sequence is displayed, those keystrokes typed in are repeated in the same order entered. Animation sequences can be saved in two different formats: ANSI and THEDRAW. A sequence saved in ANSI can be displayed using the Dos TYPE command on any computer with the ANSI.SYS driver installed (see Appendix A on how to install Ansi.Sys). TheDraw is not needed to display Ansi files once created. The THEDRAW format is used for quickly saving and loading animation sequences to disk. The Presentation Program (THEPP) can be used to display an animation sequence saved in TheDraw format. For an example of Ansi Animation, enter "TYPE SHUTTLE2.ANS" from the Dos prompt (once the Ansi.Sys driver is installed). ANIMATION BASICS ______________________________________________________________________ The actual "animation" of a screen display is done manually. In other words, the moving object is moved in steps. For each step, the object must first be erased then redrawn moved over slightly. For an example, imagine an asterisk in the center of the screen. We wish to have this asterisk move to the right. To do this, first we put a space over the existing asterisk (thus erasing it), then display a new asterisk over to the right (redrawing it). Repeating this will "animate" the asterisk, since it will appear to move. The above is actually quite easy if you use sprite editing and block copies. Problems start developing however when the object gets larger. The larger the object, the longer it takes to erase and then redraw it. This increased movement time is quite noticeable in ANSI files in particular. All is not lost however, since we can take advantage of certain characteristics found in animated movement. Most animation involves only shifting an object slightly per step. In general, the size of this shift will be smaller than the size of the object. TheDraw v3.20 The Animation System 58 Big deal you say. The point of interest is that by redrawing the object BEFORE erasing the old copy, the amount of erasing needing is reduced considerably. By redrawing the object first we overwrite a good portion of the existing object currently on the screen. Since we are overwriting parts of the original copy, there is no need to erase those parts! The only portion that does need erasing is the area not overwritten. This will normally be only one or two columns of characters. HOW TO ANIMATE SOMETHING ______________________________________________________________________ Knowing the above details about animation movement makes "animating" an object quite simple with TheDraw. All of the above movement operations (erase then redraw) can be accomplished by using a block copy. The block defined should include the object to move (naturally), plus a line of blank spaces on the side of the block OPPOSITE to the direction of movement. The line of spaces acts to erase the trailing characters as the object moves. The object is redrawn, and the old portion of the object is erased by the line of spaces. Notice that a block copy is used, NOT a block move. A block move physically changes the location of the block. Upon redisplaying the animation sequence, all you see is the block drawn in its new location. No animation is being done. To move the object, use the arrow keys and [S]tamp it in position each time you move. Press [ENTER] when done. Note that pressing [ENTER] will stamp the object one last time. Therefore, you may wish to avoid using the Stamp command on the very last movement of the object. LIMITATIONS ______________________________________________________________________ There are limitations to the animation system. Large objects will have a "ripple" as they move. In addition, they use a significant portion of the available animation space. You will be amazed how quickly even 16000 entries can disappear. Objects up to 30x10 characters in size will generally appear without problems. If you have a faster computer, this block size can be increased without too much additional ripple. As with all programs, experience will tell you what is best for a given situation. TheDraw v3.20 The Animation System 59 THE PRESENTATION PROGRAM ________________________ The Presentation Program (THEPP) included with the registered version of TheDraw is a command line driven utility intended to simplify displays and demonstrations. It is flexibly and easy to use. THEPP can display any file loadable by TheDraw (Ansi, Ascii, Binary, BSave and TheDraw formats). As with TheDraw, the filename extensions tell THEPP what format a given file is saved in. The following extensions are used (but changeable via the SETUP utility): Binary Dump .BIN Basic BSAVE .BSV TheDraw Format .TD TheDraw COM Files .COM Any other file is assumed to be either Ansi or Ascii. TheDraw format files store which page layer was being edited. THEPP displays only this page layer. If sprite mode is turned on, any page layers below the current one will appear also ("under" the current layer). THEPP takes as its parameters a list of filenames to display on the screen. This it will do as fast and efficiently as possible unless otherwise stated (on other words, you will probably want to slow things down a bit). The following options may be interspersed anywhere in the command line, before between or after, any filenames. Options are specified by using a slash following by one of these characters: Character Action p Stops THEPP from displaying any pause messages on the screen. The pauses are still performed, the user is not notified about them however. k Pause for a key from the user. This is useful for placing between files, so you can stop to appreciate what is shown. t<num> Pauses for <num> number of seconds. Valid numbers for <num> are 1 to 255 seconds. ie: t10 will pause for ten seconds. s<num> Animation display speed. This is a slowdown factor identical to the value you enter when using ALT-Q. It is used whenever THEPP displays a Ansi, Ascii, or TheDraw format file. ie: s10 slows down the file display equivalent to an ALT-Q value of 10. TheDraw v3.20 The Presentation Program 60 Character Action (continued) c Clears the screen. THEPP by default does nothing before displaying a file. If you wish to clear the screen before handle use this option. m<x>,<y> Moves the cursor to horizontal position <x> and vertical position <y>. Useful if you want to control where an Ansi or Ascii file will start to appear on the screen, or wish to display a message using the command below. ie: m40,12 moves the cursor to the center of the screen. "text" Displays any message or text between the quotes. The message MUST be terminated by a quote, otherwise THEPP assumes the rest of the command line is a message. This is useful if you wish to display your own "Press any key to continue" style message, etc... Use the "m" option described above to position messages anywhere on the screen. f<filename> Directs THEPP to obtain more commands from the specified file. This command file simply contains a list of the above commands. In addition, the command file may call upon another command file. Once that nested command file is finished, execution returns to the following instruction in the first file. Up to ten levels of nesting may be active at once. If you do not specify parameters for THEPP, the above options will be displayed in abbreviated form for convenience. Examples of THEPP usage and explanations are given below: THEPP /c/p SHUTTLE2.ANS /m34,25 /"Press a key" /k/c Clears the screen, and turns off the display of pause messages. The Ansi text demo file SHUTTLE2.ANS is displayed, followed by the message "Press a key" approximately in the center of the bottom line. THEPP then waits for a key to be pressed before clearing the screen and returning to Dos. THEPP DEMO.TD /c /m38,12 /"BLIP" /p/t10 /m1,20 Displays the current page layer of DEMO.TD, then immediately clears the screen and displays "BLIP" in the middle of the screen. The cursor is then placed at the beginning of line 20 and THEPP exits. TheDraw v3.20 The Presentation Program 61 THEPP SOMEFILE.ASC Displays the contents of the Ascii file SOMEFILE.ASC on the screen. Equivalent to using "TYPE SOMEFILE.ASC". THEPP /fCOMMAND1.FIL /m1,6 /"All done!" Makes THEPP obtain its next commands from the file COMMAND1.FIL. This file simply contains a list of command line parameters. An example might be: COMMAND1.FIL: /m1,1 /"Command file 1 running - Running command file 2" /fCOMMAND2.FIL /m1,5 /"Command file 1 resumed." COMMAND2.FIL: /m1,2 /"Command file 2 running - Running command file 3" /fCOMMAND3.FIL /m1,4 /"Command file 2 resumed." COMMAND3.FIL: /m1,3 /"Command file 3 running" In this example, command files are nest two levels deep. In other words, COMMAND1.FIL calls COMMAND2.FIL which calls COMMAND3.FIL which then exits back to COMMAND2.FIL which then exits finally back to COMMAND1.FIL. THEPP allows nesting to go ten (10) levels deep for a large amount of complexity. Running the above example would produce the output: Command file 1 running - Running command file 2 Command file 2 running - Running command file 3 Command file 3 running Command file 2 resumed Command file 1 resumed All done! Note: Conceivably, an semi-endless loop is possible. In this case, a command file would call itself (ie: replace /fCOMMAND2.FIL with /fCOMMAND1.FIL in the above example). If this occurred, THEPP would open the same command file 10 times then stop with an error message. TheDraw v3.20 The Presentation Program 62 APPENDIX A __________ SETTING UP CONFIG.SYS The ANSI driver must be installed to display Ansi color images and Ansi animation files via the Dos TYPE command. This can be done by adding a 'DEVICE=ANSI.SYS' statement to your CONFIG.SYS file. If you do not have a CONFIG.SYS file, you can create one by typing the following in your root directory: COPY CON CONFIG.SYS<enter> DEVICE=ANSI.SYS<enter> ^Z<enter> ( <-- press CTRL and Z ) If you have a CONFIG.SYS file, append the sequence with: EDLIN CONFIG.SYS<enter> #I<enter> DEVICE=ANSI.SYS<enter> ^Z<enter> ( <-- press CTRL and Z ) E<enter> For this to work properly, the ANSI.SYS file must also be in your root directory. People wanting to use a mouse with TheDraw may have to install an additional file in their Config.Sys file. If a driver must be installed, follow the above instructions except replace ANSI.SYS with the name of your mouse driver (ie: MSMOUSE.SYS or MOUSE.SYS, etc...). Additional parameters may be required. Please refer to the manual that came with your mouse for more details. There are many other useful statements that can be placed in your CONFIG.SYS file. Two which can dramatically improve the performance of DOS are: BUFFERS=10 FILES=10 Add these as stated above. If you created a new CONFIG.SYS for the DEVICE=ANSI.SYS clause by COPY CON, then append these using the second method. Enjoy! TheDraw v3.20 Appendix A 63 APPENDIX B __________ PROGRAMMERS PROGRAMMING TIPS This section is for individuals interested in using TheDraw to aid in making their programs. Effort was put into TheDraw to make it a convenient utility. PROGRAMMING IN ASSEMBLER ------------------------ Assembler programmers will find ASM format files in standard data byte format, using the DB operator. Asm files can have varying sizes depending upon the APC save mode used. Dimensions and length of the save are displayed at the top of all assembler dumps. If you Crunched the screen, you will have to use the uncruncher routine provided in ASM source code (UNCRUNCH.ASM). Values required in the various registers are documented in the file. Asm/Pascal/C (APC) Ascii files must be read as bytes and saved on the screen as words. This can be achieved using LODSB and STOSW instructions. LODSB loads into AL the character. You store into AH the attributes to display with. STOSW then writes the two bytes onto the screen. An alternate method would be to use the Bios, however that method is considerably slower. A normal 4000 byte dump is the easiest to display, using the REP MOVSB instruction. To display the image, point the ES:DI pair to B800:0000 (for color screens) and DS:SI to the screen in your program. Also load CX with the number of bytes to display (4000). Monochrome screens are based at segment B000. Direct display onto the screen will cause snow on some color videos, so you may want to move the screen a word at a time only when the video is in a vertical retrace. Vertical retrace can be detected at I/O address 3DA by testing bit 3 of that location. Be sure to clear the processor direction flag with a CLD instruction before doing any of the above operations, otherwise you possibly (50/50 chance) might not see anything on the screen. PROGRAMMING IN PASCAL --------------------- Pascal programmers have similar ease with bringing in screens. You can flash the image in a similar fashion to the Asm program using the Move procedure. A pascal NORMAL save can be displayed with the program on the following page. TheDraw v3.20 Appendix B 64 type ScreenType = array [0..3999] of Byte; var Screen : ScreenType absolute $B800:0000; begin Move (ImageData,Screen,4000); end. The above defines a variable at the absolute address of the video hardware. The importance of defining such an array will become obvious below. This assumes ImageData is the name of the pascal image dump. The MOVE puts ImageData onto the screen. Please note this is only for a full screen. To display a screen block is slightly more difficult. Our program now becomes: type ScreenType = array [0..3999] of Byte; var Screen : ScreenType absolute $B800:0000; X,Depth,Width,Offset : Integer; begin Depth := ???; {Replace ???'s with actual dimensions of} Width := ???; {block as indicated in IMAGEDATA array header} Offset := ???; {Replace ??? with position to display block} for X := 0 to Depth-1 do Move (ImageData[1+X*Width*2],Screen[X*160+Offset],Width*2); end. The variables DEPTH and WIDTH specify the block size saved in IMAGEDATA. DEPTH is the number of vertical lines in the block. WIDTH is the number of character across the block. OFFSET is the video address you want the block to appear at. It is computed with: (column*2)+(row*160)-162 Column varies 1..80 Row varies 1..25 Notice in this example we are using a loop and moving one line at a time. Lines from ImageData are placed on the video at OFFSET. The address in ImageData is advanced to the location of the next line in each loop. The video address advance 160 characters each time (the byte width of the video display). Turbo Pascal v3.0 users also have another interesting option. You can include a .BIN file into a turbo program and then display it using the above techniques. The file actually becomes part of your compiled pascal program. Once your program is compiled, you no longer need to have the DEMO.BIN file present. TheDraw v3.20 Appendix B 65 procedure DummyProc; external 'DEMO.BIN'; begin end; type ScreenType = array [0..3999] of Byte; var Screen : ScreenType absolute $B800:0000; X,Depth,Width,Offset : Integer; ImageDataPtr : ^ScreenType; begin Depth := ???; {Replace ???'s with actual dimensions of} Width := ???; {block as indiciated in IMAGEDATA array header} Offset := ???; {Replace ??? with position to display block} ImageDataPtr := Addr(DummyProc); for X := 0 to Depth-1 do Move (ImageDataPtr^[1+X*Width*2],Screen[X*160+Offset],Width*2); end. In the above program, we create pointer (IMAGEDATAPTR) pointing at the address of DUMMYPROC. The rest of the program is identical to the previous example, except all occurrences of IMAGEDATA are replaced with IMAGEDATAPTR^. The up arrow symbol at the end is very important. If you don't use it, Turbo will copy the -value- of your pointer to the screen. This will generally appear as garbage. It can be fun playing with this concept, you simply must be careful with the pointers. Pascal ASCII saves are used similar to strings. Since the ImageData arrays created do not have color attributes, we cannot directly move them to the video. The following shows two techniques for displaying these images. --- Pascal ASCII Save Example 1 --- var X:Integer; begin ClrScr; for X := 1 to SizeOf(ImageData) do Write (ImageData[X]); end. --- Pascal ASCII Save Example 2 --- type ScreenType = array [0..3999] of Byte; var Screen : ScreenType absolute $B800:0000; var X:Integer; begin ClrScr; for X := 1 to SizeOf(ImageData) do Screen[X*2-2] := ImageData[X]; end. TheDraw v3.20 Appendix B 66 The first example is easiest to understand. All we are doing is displaying each character in IMAGEDATA on the screen using the pascal WRITE function. This works because the IMAGEDATA block (in this case) is 80 characters wide, so there is no need for a WRITELN. The cursor will automatically be bumped down to the next line. The second example is similar to the first, but directly stuffs the characters onto the screen. This will be faster than the first method. Notice the Screen[X*2-2]. The multiplication is done because each character occupies two bytes of video memory. Since the first video address is 0, we add -2 to the offset to keep things aligned. To use pascal images CRUNCHED by TheDraw requires use of the UNCRUNCH.PAS file included with the package. The file contains details on its use. TURBO PASCAL v4.0 and v5.0 -------------------------- The above examples will all work for Turbo Pascal v4.0 and v5.0 users, with an exception in the use of .BIN files. The newer compilers do not support the format shown. You must use the Borland International program BINOBJ to convert the binary file (.BIN) to an object file (.OBJ). Once the object file is made, the compilers can link in the data. To use the object file, we use the following: {$L DEMO.OBJ } procedure DummyProc; external; Note: The procedure name (DummyProc here) is specified when you create the object file with BINOBJ. ie: From the dos prompt type: BINOBJ DEMO.BIN DEMO.OBJ DummyProc The above give us the desired affect. Finally, in the .BIN example above, simply replace the original DummyProc definition with the new one. TheDraw v3.20 Appendix B 67 PROGRAMMING IN C ---------------- C programmers have support similar to that for pascal. TheDraw creates the Normal, Ascii, and Crunched file formats using modern C code definitions. The ImageData arrays are used similar to the pascal case. Please note, in the following examples it will be assumed the programs are compiled in a state supporting 32-bit pointers. A C NORMAL save is the easiest to display. The following program will do this quickly and easily: #include <stdio.h> #include <mem.h> #include "image.h" main () { /* Kludge a pointer at video memory (segment 0xB800, offset 0) */ void far *screen = (void far *) 0xB8000000; memcpy (screen,ImageData,4000); /* Move image to screen */ } The <mem.h> file reference contains the definition of the memcpy routine. IMAGE.H is assumed to contain the array ImageData created by TheDraw (you can change this to anything else naturally). The void data type used is a modern C convention. If your compiler doesn't support this, use type char instead (or whatever type your compiler wants for parameters to memcpy). To above is for a full screen image. To display a block involves a little more work, as in the pascal example. #include <stdio.h> #include <mem.h> #include "image.h" main { void far *screen; int depth = ???; {Replace ???'s with actual dimensions of} int width = ???; {block as indiciated in IMAGEDATA array header} int offset = ???; {Replace ??? with position to display block} int x; for (x=0; x++; x>=depth) { screen = (void far*) 0xB8000000+x*160+offset; memcpy (screen,ImageData[x*width*2],width*2); } } TheDraw v3.20 Appendix B 68 As before, the variables DEPTH and WIDTH specify the block size saved in IMAGEDATA. DEPTH is the number of vertical lines in the block. WIDTH is the number of character across the block. OFFSET is the video address you want the block to appear at. It is computed with: (column*2)+(row*160)-162 Column varies 1..80 Row varies 1..25 A loop is used in this example to move one line at a time. Lines from ImageData are placed on the video at OFFSET. The address into ImageData is advanced to the location of the next line in each loop. The video address advance 160 characters each time (the byte width of the video display). The ASCII format is a bit easier to use in C than Pascal. By taking advantage of the 0 terminated strings of C, we can display a ASCII image by simply doing the following: #include <stdio.h> #include "image.h" main { printf ("%s",&ImageData); } Note: To use this technique requires the ImageData array be modified slightly. TheDraw does not place the required 0 byte on the end of the array. To do this is quite simple however. Simply remove the array length indicator. ie: unsigned char ImageData [] = { ...data here...}; The C compiler upon seeing this will tack the required zero on the end of the array (since it looks like a string). An alternate technique for displaying ASCII format files is similar to the second pascal example (for doing the same thing). The following example shows this. TheDraw v3.20 Appendix B 69 #include <stdio.h> #include <mem.h> #include "image.h" main { void far *screen; int x; for (x=0; x++; x>=4000) { screen = (void far*) 0xB8000000+x*2; memcpy (screen,ImageData[x],1); } } Characters are copied one at a time from the ImageData array to the video memory. This will in be faster than the printf example, since the overhead of going through the operating system is removed. To use C images CRUNCHED by TheDraw, you must use the code in either UNCRUN_N.OBJ or UNCRUN_F.OBJ (depending if you are using a Near or Far code model). The file UNCRUNCH.H contains examples on their usage. TheDraw v3.20 Appendix B 70 PROGRAMMING IN BASIC -------------------- Basic programmers are a little more limited, not because of lack of commands, but lack of speed. Therefore TheDraw creates the BSave files with all addressing information already programmed. All you have to do is type 'BLOAD "filename.BSV"'. The screen segment is automatically set, so you don't have to bother with DEF SEG=etc... However, if you wish to override the display segment default, try the following: 'DEF SEG=&HB800 : BLOAD"filename.BSV",0'. For monochrome video users, replace the B800 with B000. TheDraw allows partial block saves for basic files. These files will always be 80 characters wide. This is a limitation of BLOAD which we all must live with. They can start and end at any line however, so you could load a full screen then just load small block images to update those parts of the screen needing it. Make sure you build the partial-block images in TheDraw in the exact screen location you want them to finally appear. If you save a block starting on line 5, and ending on line 8 that is where Basic will display it. If you have additional ideas for this section, I'd like hear about them!

This has been corrected. ______________________________________________________________________ 06/05/86 - Version 1.02 Steven Mills discovered a bug in the file loading routine that caused TheDraw to flag valid filenames as invalid. It has been squashed. Changed the program to not allow the user to enter a code #26 or code #27 into a text screen. A code #26 is the Dos end of file marker, and entering it means loss of all following text upon displaying the file or reloading it back into TheDraw. A code #27 is the ANSI driver signal character. Supposedly ANSI ignores invalid sequences, but allowing the code created "false" ANSI codes which caused loading problems. ______________________________________________________________________ 07/31/86 - Version 1.03 Upon prompting from Carl Ehmann, output line length limiting has been added. This will facilitate other programs which cannot load lines conceivably going over 1300 characters (such as RBBS). Color changes can now be accomplished using the Ctrl-Left and Right arrow keys to increment the fore and background colors respectively. ______________________________________________________________________ 08/15/86 - Version 1.10 (later changed to v2.00) Changes in a big way. New features include: ANSI Animation, Line Drawing, Ruler, movement of blocks UNDER other text and much more!! Quick color change keys have been expanded to use the Ctrl-Up, Down, Left, and Right keys in a more logical manner. ______________________________________________________________________ 09/13/86 - Version 2.01 A few more enhancements. Pop-Up help, and macros have been added to the new registered version of the program. Also a few aspects of the animation editor have been sped up. TheDraw v3.20 History 73 R E V I S I O N H I S T O R Y (cont): 09/19/86 - Version 2.02 Fixed a slight bug which was causing TheDraw to display the wrong Help Screen (in registered version). Also, the registered version wasn't keeping track of where its overlay was. ______________________________________________________________________ 09/27/86 - Version 2.03 Carl Ehmann noticed yet another glitch (what would I do without him?). The Ascii save routine was using ANSI codes to advance the cursor to the next line. ______________________________________________________________________ 11/28/86 - Version 2.04 Ray Buti discovered an oddity with the Pascal screen save. If you used a single quote "'" TheDraw didn't compensate for it. Therefore when Turbo Pascal compiled that screen it complained. Ray also noticed that characters under #32 were missing the "#" required by Turbo. These have both been cured. In addition, the animation load routine has been made more reliable. Occasionally movement just involving the cursor (no text) would be lost. Other improvements were made to make animation screen files smaller and display faster. ______________________________________________________________________ 03/06/87 - Version 2.10 Support for monochrome monitors has finally been added. Don't ask why I never did it before... The glitches Paul Pacter (and many other people) found with IBM PC Ctrl-Up/Down keys has been eliminated. I would have never noticed that glitch, so many thanks! Kent Godding made an excellent suggestion for a ansi-file slow down routine. This has been added. Lastly, a few changes were made to the command structure to clarify things and many prompts were cleaned up. TheDraw v3.20 History 74 R E V I S I O N H I S T O R Y (cont): 06/20/87 - Version 2.20 BSave saves fixed to operate properly for monochrome monitors. Ansi files now output <esc>[40m color sequences to clear screen to black color before doing anything else. Thanks to Barry Simon for bringing this oversight to my attention and also suggesting command line filespecs. Some new items were added, most notably full screen editing. Thank Ray Buti for finally bugging me enough to add it. Also extended options for Asm, Pascal, and new C storage modes to crunch and store only Ascii in addition to the original normal (4000 byte) mode. Thanks to Douglas A. Nicklow for suggesting the C storage capacity. ______________________________________________________________________ 08/22/87 - Version 2.21 Fixed a minor glitch with window sizes being slightly off. Also I missed a problem in the registered version. TheDraw was not using the overlay path entered by the Setup utility when initializing. So much for learning from mistakes (ie: it happened before). In addition, using a command line filespec sometimes loaded a Ansi or Ascii image with a random background color. Needless to say, everything has been fixed. ______________________________________________________________________ 04/28/88 - Version 3.00 Many, MANY changes. TheDraw totally rewritten to take advantage of Turbo Pascal v4.0. A new title screen, dynamic allocation of screen layers and animation space (up to 16000 animation entries and 8 page layers can now be used), multi-layer Sprite editing, dos shelling (suggestion from Billy Noto), and a new high-speed TheDraw format data file have all been added. TheDraw now incorporates its own Ansi driver so Ansi/Ascii file loading is much faster. The animation system has been greatly expanded. Five new animation scanners have been added (ANGLE, GATE, PYRAMID, SQUARES, and WIGGLE). Animation markers(R), "include files", animation pausing, support of animation on multiple page layers (no longer restricted to just one page), global animation screen copies, and more have all been added. Animation sequences can now be appended together. The registered version supports easy animation editing. A couple of bugs were fixed. The pascal saver was leaving spurious single entries on the end of lines (yet another discovery of Ray Buti <grin>). The Ascii Save no longer outputs spaces on the end of every line. TheDraw v3.20 History 75 R E V I S I O N H I S T O R Y (cont): (cont) The Setup utility has been vastly overhauled and now allows configuring of the TheDraw edit screen colors, TheDraw keyboard commands(R), and many other parameters. ______________________________________________________________________ 09/09/88 - Version 3.10 Support for the Microsoft Mouse has been added, making cursor movement and the marking of blocks easier. Five additional character sets have been added. These are accessed via CTRL-F(1-5). With this revision goes a new function key screen (ALT-F). Finally, a few bugs were eradicated. Many people reported CTRL-Up/Down keys were not working. They did work, however the status display was not always updated (thus causing the following confusion). TheDraw now allows filespecs without extensions to be used again. In addition, the default filespec extensions can be changed using the Setup utility (Ray Buti can now change .PAS to anything he likes <grin>). The Setup utility Defaults option now works as advertised. Finally, the keyboard driver for Ctrl-Up/Down has been changed yet again. With the last revision, a few computers were gained but the PCjr was lost. 04/04/89 - Version 3.20 Pull down menu system has been added to TheDraw. The program can now be totally controlled by use of a mouse. Various small details that escaped detection regarding the mouse were corrected. TheDraw has a new storage format -- COM files. Separate programs useful for batch files and the like. They work with blocks and (naturally) the entire screen. A few bugs floating around the program have been cured. When attempting a block save, TheDraw would sometimes display and save the wrong screen portion. The ALT-U command would not processing blinking colors properly -- thanks to Darin May for pointing this out. The ALT-L file lister had a minor problem when there were exactly 124 displayed items in the directory. You could go down to the next page even though there was nothing on it. Animation screen copies might possibly fail if they run out of room. What the user saw didn't necessarily match what TheDraw thought was there until everything got redrawn. The problem with CTRL-UP/DOWN simply won't go away. The driver will work for 99% of machines, but certain computers with non- compatible keyboard hardware will lockup (notably the Tandy 1000A and HX). The SETUP utility now has a provision for deactivating the driver completely. (R) = Feature in Registered Version of TheDraw Only TheDraw v3.20 History 76 T H E F U T U R E Look for these features in the next version of TheDraw: Object format files suitable for LINK, TC 2.0, TP 5.0, etc... Object files were scheduled to appear in v3.2, but compatibility with various compilers proved a sticky point. Block and object support in TheDraw format files.
