WhizWare 635 Kendrick Rd Milner, GA 30257 The analyst that designed �WhizDraw is Thomas C. McIntire. Write to Tom if you have any problems or wish to comment on this software. He will appreciate the input. His e-mail address is: whizware@bellsouth.net |WhizDraw WhizDraw is our generic name for the following software components: WhizDraw.EXE - the main program (WhizDraw.BAS is the source file) WhizDraw.OVL - overlay file -- menus, text and machine language routines WDhelp.EXE - this program, which is called by WhizDraw.EXE WDhelp.DAT - the Help data file displayed by WDhelp.EXE WDhelp.TXT - the Help source file input to WhizHelp.EXE WDJetXL.EXE - driver for HP PaintJet XL -- see �Pjet (and WDJetXL.BAS) WDGraf.EXE - Graphics Files Utility -- see �Graf (and WDGraf.BAS) WD???.FNT - standard character sets -- see �Fonts *.MSK - sample mask files -- see �Masks *.ICN - sample icon files -- see �Icons WhizDraw.EXE, WhizDraw.OVL and WDEGA.FNT must be in the run-time path. WDhelp.DAT must be in the same path as WDhelp.EXE; they must both be in the same path as WhizDraw.EXE to get Help from the WhizDraw menu. WDJetXL.EXE must be in that same path if it is to be called via WhizDraw. Note: Use this program only for an HP PaintJet XL--the odd control codes it uses will drive any other printer bonkers. If you do not have this specific printer, delete this program from your run time path. (If selected then, the request will simply be ignored). |Masks Masks is our generic name for full-screen images stored in disk files. Mask files are large: 112,000 bytes. (See �Icons for comparison.) We suggest using a file name extension of .MSK for mask files. If no name extension is typed, dot-MSK will be added for you. Also see �Load and �Save and �Graf ... |Icons Icons is our generic name for part-screen images stored in disk files. Icon files are only as large as need be. (See �Masks for comparison.) We suggest using a file name extension of .ICN for icon files. If no name extension is typed, dot-ICN will be added for you. Icon files are created by copying a cut-image from memory to disk. (When loaded they are copied from disk into this same buffer.) See �Cut and �Paste for more about this. Also see �Load and �Save and �Graf ... |Fonts Fonts is our generic name for printable character sets stored in disk files. Font files are always 7,176 bytes in size. We suggest using a file name extension of .FNT for font files. If no name extension is typed, dot-FNT will be added for you. To customize individual characters select �Type from the �Draw menu then hit . Instructions for using this feature are shown at that time. Also see �Load and �Save ... |Mouse WhizDraw presumes use of a 2-button Mouse. (Extra buttons are ignored.) Mickey's right paw works the same as the key and his left paw works the same as the key. This can be reversed while in any �Draw mode. Hit any time while running �WhizDraw to "flip flop" how this program interprets which paw is for what. (The setting you choose is stored in the WDhelp.DAT file.) Mickey's paws are sensed when depressed then released. The Enter paw works like an "auto-repeat key" during �Dots and �Lines and �Zoom and while editing �Fonts but in all other cases the buttons are not acted on until "clicked". WhizDraw assumes your mouse driver has already been loaded before WhizDraw is started. When you �Quit the mouse driver is left in memory. WhizDraw does not fool with the driver's sensitivity or speed parameters --they remain as they were before WhizDraw is run. |Keys Keys on the keyboard work generally as expected. However: The key is used to change the spacing interval of cursor movement done via the cursor-arrow keys. Normally it moves 1 dot-space at a time. will change this to 10 dot-spaces at a time. Hitting again resets the interval back to 1. (This key is active only while in �Draw routines.) The spacing interval set by while doing �Draw �Type is either one dot-space or the size of one character cell (8 x 14). + has a special use during �Paste and �Load for �Masks ... See those pages for that definition. See �Fonts about the only time the key is used. During �Draw routines resets the from-pointer. In some �Draw routines is an "un-do" key. See �Colors about how + <0...9> and are used. See the next page about special functions assigned to F-keys ... | Is an "auto-cut" key. It will automatically reposition the "cut-box" to surround the same image area last operated on by a �Cut or �Paste function. (This is handy when you have been editing an �Icons image and want to update the cut buffer.) is only active while in �Cut mode, PS. Flip-flops (reverses) the meaning of �Mouse buttons. Is operable only during �Zoom editing. It stores the current X and Y positions and pixel color setting each time this key is hit in a disk file called WDPLOT.DAT. This file is automatically deleted when WhizDraw first begins and closed in conjunction with �Quit (so, if its contents are to be used the file must be preserved before this program is executed again). Note: This capability is peculiar to a package called �WhizKids ... Displays cursor X and Y positions during �Draw routines. At that point, hitting ... will save the X and Y coordinates displayed so that they may be recalled--and the cursor moved to--the last position saved with or , etc., whenever the display is not on. Hitting any key (or button) turns off the display. |Menus Menus in WhizDraw are lists of things you can do--the way you get around. Notice that the key words in each menu begin with unique capitals. A function can be selected from a menu in one of three ways: By hitting its initial letter on the keyboard or by moving the cursor with arrows or the Mouse to that word then hit . is always usable, from anywhere, to get to menu-mode. Switching from �Draw routines to menu-mode also resets the from-pointer and saves your Rembrandt in the "un-do" buffer. See �Keys for more. |Colors Colors are selected by key-codes: 0 = Black 8 = Gray 1 = Blue 9 = Hi Blue (Hi means high intensity or bright) 2 = Green A = Hi Green 3 = Cyan B = Hi Cyan (Cyan is also known as Marine Blue) 4 = Red C = Hi Red 5 = Magenta D = Hi Magenta (sort of Purple or Pink) 6 = Brown E = Yellow (Brown may appear as a shade of Red) 7 = White F = Hi White These keys (0-9 and A-F) are like hot keys during �Draw routines. During �Draw �Type use + the key-code to set colors. Notice that these codes are the same as hexadecimal values for 0-15 (these are the color codes that are used in BASIC). |Save Save means copying from memory to disk. When you select Save a second menu selection is necessary to specify what you want saved. Having selected Save, and a file type, you must next supply (type) a file specification according to DOS rules for such, then hit . If no dot-whatever is typed, a default name extension is added automatically. See �Masks or �Icons or �Fonts for more about this. If a filespec is displayed and it is correct, just hit . Remember that if a file already exists that exactly matches your file specification it will be updated. (Destroyed?) If DOS doesn't like your file specification you will hear a two-tone beep to let you know the Save could not be done. is always usable, from anywhere, to get to menu-mode. |Load Load means copying from disk to memory. When you select Load a second menu selection is necessary to specify what you want loaded. Having selected Load and a file type you must next supply (type) a file specification according to DOS rules for such, then hit . If no dot-whatever is typed, a default name extension is added automatically. See �Masks or �Icons or �Fonts for more about this. Also, when loading Masks, + "overlays" a mask on top of whatever is already on screen, vs. just , which "replaces" an existing screen. If a filespec is displayed and it is correct just hit . Remember that if a file already exists in memory it will be replaced (overwritten) by the file being loaded. If DOS doesn't like your file specification you will hear a two-tone beep to let you know the Load could not be done. is always usable, from anywhere, to get to menu-mode. |Draw Draw is a second level menu of 18 drawing routines. Once one is picked you stay in that "mode" until a different one is selected. �Zoom enlarges a 16x16 dot square area of the screen so you can better see the dots and it lets you "edit" them. �Lines & �Boxes & �Ovals & �Arcs & �Dots are actual drawing routines. �Erase & �Fill & �Unfill & �Xcolor are automatic coloring routines. �Invert & �Mirror & �Rotate are turn-this-image-around routines. �W x 2 & �H x 2 are enlarging routines for doubling the size of an image. �Cut & �Paste are for moving images around on the screen or between the screen and disk files-- �Icons we call them. �Type activates the keyboard so that text may be added to a drawing. When you pick any drawing routine the Draw menu disappears and you are then in the mode selected. While drawing, exits to the Draw menu; from there, exits to the main menu. |Graf Graf may be selected to link to our WDGraf.EXE program: A utility useful in several ways... It can "convert" a mono-type .MSP file --an image file in a format common to several other drawing packages (and some scanner software) so that it can be imported into WhizDraw. It can also "convert" WhizDraw �Masks and �Icons and CogoWhiz files (and vice versa). During any of these conversions it is also possible to "rotate" an image. This is different than that done by �Draw �Rotate --an MSP or MSK file may be re-generated as if it had been saved with the image turned on its left side. Icon files may be turned a specific number of degrees (1-90). Considering up as 0, a positive number of degrees turns the image to the right; a negative number turns the image toward the left. (To go beyond 90� turn n-degrees then use �Invert and �Mirror to get what you want.) During any of these conversions it is also possible to "down scale": An image may be reduced by half, by a third, and so on. This is a powerful tool. But. See the next page for some "limitations" ... | WDGraf.EXE may be run from command mode as a free standing program or linked to via the �Graf option on the main WhizDraw menu. If done this way, know that: Any on-screen "drawing" being worked on will be lost! Best do a �Save if necessary, before choosing the �Graf option. (Use �Help Status if you can't remember what you are doing.) Scaling: When an existing image is "scaled down" some detail is bound to be lost. (Also see the note below about over-writing an existing file.) Rotation: The output image is simply re-plotted pixel-by-pixel. Because the screen is arranged with 640 pixels across, but only 350 vertically, the "edges" of large pictures can be lost. And proportionality suffers; what used to be round will likely wind up as ovals. When rotating �Icons some detail may become "fuzzy". (Because: The arithmetic involved produces fractions but pixel positions are finite integers--a pixel cannot be turned on "between" absolute positions; rounding puts them in the nearest possible whole-numbered position.) Files: WDGraf reads an existing file and creates a new one. You name the "source file" and the "target file". Just like elsewhere in the wonderful world of DOS, if a target file already exists having a matching name it will be over-written. (The previous file contents will be lost). Caveat. | Filtering: If Y-for-Yes is selected, after an image is produced it will be scanned for "isolated pixels". In a solid-color area, for example, if a lone pixel is found whose color differs from all of those adjacent to it, it will be automatically changed to the color of its neighbors. Smoothing: If Y-for-Yes is selected, after an image is produced it will be scanned for "rough edges". If an image is enlarged using �W x 2 or �H x 2 for example, this function can be used to "fill in" pixels between diagonally opposed matching colors. (This frequently produces much smoother shapes.) NOTE: For very large images--especially for full Mask files--be patient. Both filtering and smoothing are inherently slow processes. In many cases you can see individual pixels being changed. In large "blank" areas, however, nothing will be seen to be happening thus one might think the program has gone into limbo. Be patient. Go get a cup of coffee or something. The wait will usually be well worth it. These two options can save you a lot of work by reducing the amount of �Zoom editing you might otherwise have to do. |Pjet Pjet is used to send a full screen color image to an HP PaintJet XL printer. This is done via a separate program--WDjetXL.EXE--that can only be used with that model of printer. When Pjet is selected several options may be specified before the call (via SHELL) to WDjetXL is done: The letter A will Abandon the paper--leaving it where it is when the program ends, so an immediate restart will continue on the same sheet. The letter L will indicate that the output mode is to be Landscape--as opposed to Portrait, viz the default mode. The letter S will indicate that the output is to be Scaled--as opposed to "normal", viz the default mode. PS: Scaling gives a more proportionally correct picture. Q=rrr means Quit after rrr monitor dot Y-lines have been printed (0-349). X=ddddd means start in horizontal (printer) column ddddd. Y=ddddd means start at vertical (printer) row ddddd. (ddddd is "decipoints", 1/720 of an inch-- 360 = a half-inch, etc.) Note: All option indicators must be separated by spaces. | The default output (DOS) device is LPT1. If your printer is set up as LPT2, for example, then include LPT2: as an option when this program is started. Notice the colon; it is a must. This same thing works if your printer is set up as a serial device. For example, type COM1: as an option to route output to serial port 1. Normally, when called from the �WhizDraw menu, what is then on the screen is what you want printed. It is also possible to supply the name of one of your �Masks as a start-up option. Whenever this is done, the source file name must be the first option named. Done this way, from the WhizDraw menu, what is then on screen will be preserved as is--the file from disk is the one that will be printed. It is also possible to start WDjetXL.EXE as a stand alone program, viz: WDJETXL MYFILE.MSK L S Q=90 컴컫컴� 컴컴컫컴컴 � � � � � � � 읕 print monitor Y-lines 0-90 then Quit � � � 읕 Scale switch is on � � 읕 Landscape mode is on � 읕 a WhizDraw mask file (full screen or 112,000 bytes) 읕 our PaintJet XL program (a dot-EXE file) | During any of this exits to the main menu if selected from within Whizdraw (or returns to DOS if WDjetXL is jump started). Which is what you should do if you don't have this model of printer. In fact if your printer is different, you should delete WDjetXL.EXE from your run-time path. (Then if selected on the Menu the request will be ignored.) To send your art work to other printers maybe you can use DOS capabilites. Check your manuals. Look closely too, at the (DOS) GRAPHICS command. |Help Help is the menu selector for one of three types of info: Status -- For where you are and what you have loaded, etc. �Fonts -- Displays all of the characters in your currently loaded font file so you can see what number to punch with , or to "capture" a character to be auto-duped while in �Draw �Type mode. How to -- Calls this program, WDhelp.EXE (via SHELL). Notice that this is a free standing program and can be run directly from DOS command mode. (In which case it exits back to DOS.) Also, this program can be called after using �Cmnd to shell to DOS. Which is a useful trick if WDhelp.EXE and WDhelp.DAT are not in your run time path. PS: See �WhizHelp about how WDhelp files are created and maintained-- �WhizWare developed a special package for making it easy to produce "on-line help" for any software product (or for any subject). |Cmnd Cmnd is an abbreviation for Command: A means for temporarily exiting �WhizDraw to COMMAND.COM (to DOS command mode). A common use of this is for when you get a beep because a �Load failed. For example: Select Cmnd, go to DOS, then use DIR to see your file names. When you are finished sightseeing or whatever you do, BE SURE to use the DOS EXIT command to return to WhizDraw. See this: When you SHELL out of WhizDraw your work screen is being held in a background video buffer. If you can't, won't or don't EXIT back to WhizDraw you are going to lose your masterpiece. Because the machine is still in graphics mode when you shell out of WhizDraw no cursor will appear while you are typing. (See �Type also.) Note: Many DOS commands should not be used in SHELL mode. Things like GRAPHICS will hang the system and blow your show. No program should be executed that alters the monitor's adapter settings either. Hint: Do a �Save first if you are nervous about any of this. |Quit Quit is the way to exit �WhizDraw (the ONLY correct way). Return is to whence you came from. No, we do not aggravate you with a warning that an on-screen image may be lost because you forgot to �Save it. (Use �Help Status if you can't remember what you are doing.) If a batch file invoked WhizDraw, return is to the next line in that file. If you shelled to WhizDraw, return is back to the calling program. If started as a DOS command, return is back to DOS command mode. See �Cmnd as an alternative for quick out-and-back DOS chores. |Zoom Zoom enlarges a 16x16 dot square area of the screen so you can better see the dots, and it lets you "edit" them. The area to be zoom-edited is outlined by a box-shaped cursor. Move the box until it surrounds the area wanted, then hit . A grid is displayed, each cell depicting 1 dot of the area to be edited. Editing of individual cells works similar to �Draw �Dots --see �Colors also about how to change the colors of the cells. As you edit cells in the grid notice that corresponding changes occur in the area selected for zoom-editing. removes the grid so you can move the box-shaped cursor to a new location. Also, while editing, the key works as an "un-do" key to restore your screen as it was before the current grid was selected. See �Keys about a special use of during Zoom. |Lines Lines are drawn from where you started (the from-point) to where you are at (the to-point) when you hit . That point then becomes the from-point for the next line. This works such that, by holding down Mickey's paw and moving slowly, any shape can be drawn much as could be done with a pencil. See �Colors about how to set the color for drawing lines. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Boxes Boxes are drawn from where you started (the from-point) to where you are at (the to-point) when you hit . That point then becomes the from-point for the next box. The guide lines for boxes are a rectangle (dashes). Notice that the from-point and the to-point are diagonally opposed corners. See �Colors about how to set the color for drawing boxes. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Ovals Ovals are drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The from-point of an oval is the radius point. The to-point of an oval is a point on the circumference. An oval can be either a circle or an ellipse. The guide line for an oval is a dotted-line radius. If cursor movement is along only a vertical or horizontal axis the result will be a circle. If movement is along both a vertical and a horizontal axis, an ellipse will be drawn. See �Colors about how to set the color for drawing ovals. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Arcs Arcs are drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The from-point of an arc is the radius point. The to-point of an arc is a point on the circumference. The guide line for an arc is a dotted-line radius. If cursor movement is along only a vertical or horizontal axis the result will be a half circle If movement is along both a vertical and a horizontal axis, one fourth of an ellipse will be drawn. The quadrant of one fourth of an ellipse is determined by the to-point. If the cursor is up and to the left of the from-point the arc will be drawn as if from 9 o'clock to 12 o'clock. Down and to the right is similar to three o'clock to 6 o'clock, and so on. See �Colors about how to set the color for drawing arcs. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Dots Dots are drawn by hitting . This works such that, by holding down Mickey's paw and moving slowly, any area can be colored much as could be done with a pencil. See �Colors about how to set the color for drawing dots. |Erase Erase is, effectively, a filled-in box drawing function done from where you started (the from-point) to where you are at (the to-point) when you hit . That point then becomes the from-point for the next erase-box. The guide lines for erasing are a rectangle (dashes). Notice that the from-point and the to-point are diagonally opposed corners. See �Colors about how to set the color for erasing. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Fill Fill works to fill in an already drawn figure with a given color. The figure to be filled must be fully outlined with a color other than that with which it is to be painted. And the entire outline must be of the same color. See �Colors about how to set the color for using Fill. Also, during Fill, the key works as an "un-do" key to restore your screen as it was before the current Fill was selected. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Unfill Unfill is conceptually akin to �Fill (but it is different). Suppose you have a figure which is a solid color: Use Unfill to run around inside that figure and change the "edge" to a different color. Notice another important difference: Unfill starts at your from-point and runs "upwards" until a pixel is found whose color is not the same as the one at the from-point, then it attempts to follow the outline of the figure changing the edge colors as it goes ... See �Colors about how to set the color for using Unfill. Also, during Unfill, the key works as an "un-do" key to restore your screen as it was before the current Unfill was selected. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. IMPORTANT: See the next page ... | �Unfill colors with the first (primary color) while scanning for another color. If you select Unfill twice in succession without changing your color settings you may not like what will happen: The logic of this routine is such that it will go on, and on, and on, and on ... Any keyboard key can be used to break out of this seemingly perpetual situation, and can be used immediately thereafter to restore the screen to the "as was" image (same as the screen looked the last time a Menu selection was made). |Xcolor Xcolor is a mnemonic for "exchange one color with another". The guide lines for Xcolor are a rectangle (dashes). Notice that the from-point and the to-point are diagonally opposed corners. Two colors must be specified: The from-color and the to-color. See �Colors about how to set colors. The first color set is the from-color. The second color set is the to-color. The second color set is also the one the guide-lines are drawn in. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. |Invert Invert will "flip" an image about its horizontal (middle) axis. The area to be inverted is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The guide lines for Invert are a rectangle (dashes). Notice that the from-point and the to-point are diagonally opposed corners. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Suppose you had an image:  then Invert would cause:  |Mirror Mirror will "reverse" an image on its vertical (middle) axis. The area to be reversed is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The guide lines for Mirror are a rectangle (dashes). Notice that the from-point and the to-point are diagonally opposed corners. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Suppose you had an image:  then Mirror would cause:  |Rotate Rotate copies and pivots a rectangular image 90�. The area to be rotated is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The guide lines for Rotate are a rectangle (dashes). The pivot-point is the corner marked as the to-point. The direction of rotation is based on the vector of the diagonal: Along a line from the from-point towards the to-point. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Suppose you had an image: 커 then Rotate would cause: 켸 Also see �Graf about how "large images" can be rotated and about turning a specified number of degrees in the 0-90 range. |W W x 2 is shorthand for "double the Width of an image". The area to be enlarged is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The guide lines for W x 2 are a rectangle (dashes). When done, the cursor is moved such that hitting again will enlarge the image once again. Notice that the from-point and the to-point are diagonally opposed corners. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Also see �Graf about how images can be "scaled". |H H x 2 is shorthand for "double the Height of an image". The guide lines for H x 2 are a rectangle (dashes). The area to be enlarged is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . When done, the cursor is moved such that hitting again will enlarge the image once again. Notice that the from-point and the to-point are diagonally opposed corners. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Also see �Graf about how images can be "scaled". |Cut Cut is short for "cut out and capture a rectangular image in a buffer". The captured image can be output elsewhere on the screen using �Paste -- and (or) it can be saved in a disk file. See �Save and �Icons ... The area to be cut out is outlined by a box drawn from where you started (the from-point) to where you are at (the to-point) when you hit . The guide lines for Cut are a rectangle (dashes). The maximum size that an image (rectangle) can be is approximately two-thirds of a full screen. A two-tone alarm will sound if an attempted Cut is too large. Notice that the from-point and the to-point are diagonally opposed corners. Returning to the menu or use of the key will establish a new from-point at the position the cursor is then at. Also see �Keys about a special function assigned to . |Paste Paste is used to output a rectangular image currently held in a buffer area. An image to be pasted can be loaded into this buffer by use of either �Cut from the �Draw menu or by use of �Load from the main menu. See �Icons and �Save also, for more about this. The guide lines for Paste form a rectangle (dashes) that is of the same dimensions as that of the image being held in the cut buffer. This rectangle can be moved to a desired location on the screen. is used to cause Paste to replace that portion of the screen with the image held in the buffer. + works similar, but, the result is an "overlay" of the cut buffer image "superimposed" on whatever is already on screen. Meaning: Only non-zero (colored) pixels are output. A two-tone alarm will sound if any portion of the guide-line rectangle is positioned off-screen for a "regular paste" but not for an "overlay". See �Keys also, about a special function assigned to . |Type Type turns off the drawing cursor and turns on the typewriter keyboard. A simulated text-cursor shows where keyboard input will occur. Both a background and a foreground color may be set for typing. See �Colors about how to set colors. The first color set will be used for the background. The second color set will be used for the characters. (Remember to use to set color codes.) Other special-use keys and their functions are: to change arrow key spacing (1 dot or 1 character cell) to move to the upper left corner of the screen to move to the end of a line (right-most column, same line) to duplicate the last character typed to restore the screen as it was before to customize individual characters See �Load and �Save and �Fonts for more about this. |WhizKids 複複複複複複複複複複複複� � � � For the kids we have: � � WhizKids � � To make learning fun! � � � 賽賽賽賽賽賽賽賽賽賽賽賽� It is a connect-the-dots program. Some drawings have numbers by the dots. Some have letters. Cursor arrow-keys are used to pick one of four choices --one is correct--the next number or letter to be "connected" in sequence. This program was designed to help pre-kindergarten children to learn to count. To learn the alphabet. To recognize the shape of numbers and letters. And to learn that learning can be fun. This program was designed with the help of an expert teacher--the director of an early childhood learning center, with many years of experience teaching the 3-5 years age group. WhizKids runs on nearly any DOS based machine that has an EGA or VGA monitor (or equivalent). The basic package contains twenty drawings and twenty matching full color image files ... | When all of the dots are connected--the lines are drawn as numbers or letters are picked in sequence--that "drawing" is overlaid by the corresponding "real graphics art" image as reward for a job well done. Only two other keys are used by the student besides the four arrow keys: is used to pick a drawing from a menu to work on. is useful to quit a drawing early. For the teacher: WhizKids also has on-line help built in. It is the manual for the program, and it contains suggestions for making effective use of it. See now another use of �WhizDraw --it is how we made the drawings for WhizKids. With it you can create ones of your own design to suit particular student needs. |WhizHelp Tired of building on-line "Help" schemes? All of that text! And a way to display it. And an "indexing" means for the operator. With Mouse or keyboard "pick this" capability. �WhizWare has a whizzing solution. We call it WhizHelp--A programming tool that eliminates a lot of drudgery, saves you time and money and produces a consistent, friendly methodology to your users. The concept: Your "help" screens are in an ASCII text file; one that you build (and maintain) using your shop's preferred word processing program. The program that "plays" these pages and that manages user index access and page scrolling is our own WhizHelp.EXE program renamed to fit in with your package's file naming scheme. It reads your "help data file" and pops whole pages on the screen quickly. The essence of it all is WhizHelp.COM--a compiler type of program that converts your .TXT file to a .DAT file and copies and implants into your version of the core program color parameters, a screen mode code, and the name of your data file. All automatically. And it produces an error | report, if need be, to warn you of pages that do not conform to the simple rules necessary to make all of this work. Notice you have to do only three things: Create the input source file, run this tool, and simply include a SHELL line inside your package that can be triggered by the operator when they want to get help. Sure, this package was designed for programmers, but others can make good use of it too: Create on-line help about any subject. Like, price lists, order-completion check lists, quick reference guides to complicated procedures, and so on. All of this works in 8086 machines with as little as 512 Kb memory but is, of course, even faster on the newer ones: Effectively, any machine running under DOS 3.0 or later.
