- CompuServe Graphics System
- Version 5.00
-
- for the
- IBM PC, XT, AT, PCjr, PS/2 (and compatibles)
- with
-
- Hercules Monochrome Graphics Adapter
- or
- Color Graphics Adapter (CGA)
- or
- Enhanced Graphics Adapter (EGA)
- or
- Multi-Color Graphics Array (MCGA)
- or
- Video Graphics Array (VGA)
-
- and
- Graphics Printer
-

-
-
- Execute the program by typing CSHOW (and a <Carriage Return>) at your DOS
- prompt. (Also see START-UP OPTIONS, below.) The program will require
- approximately 192k of available memory. If the program displays an
- "Insufficient memory" message, you need to make more memory available.
- (Remove some memory-resident programs, for example.)
-
- Start-Up Options
- ================
-
- CompuShow should recognize the type of video adapter present in your computer
- (Hercules, CGA, EGA, MCGA, or VGA). However, if you have a "super-EGA" (480
- line) adapter, you'll need to tell the program about it. Also, although the
- program has been tested on PS/2 MCGA and VGA systems, it may fail to
- recognize the presence of a non-IBM VGA adapter. "Command-line switches"
- allow you to identify your video hardware:
-
- A "+" switch is used to bypass the automatic video "detect" routine, in a
- situation where the program fails to detect the correct video adapter.
-
- >CShow +M (or +m) MCGA mode
- >CShow +V (or +v) VGA mode
-
-
-
-
-
-
- Page 1
-
-
-
-
-
-
-
- A "/" switch is used to indicate the presence of a 480 line "super-EGA"
- adapter. The program knows about several:
-
- >CShow /A ( or /a ) Ahead Systems
- >CSHow /G ( or /g ) Genoa
- >CShow /T ( or /t ) Tseng
- >CShow /V ( or /v ) "VGA" (eg. the Zenith "VGA")
-
- These commands specify graphics modes 38, 115, 37, and 18 respectively, which
- puts each card in 480 line EGA mode. Other 480 line cards can be identified
- by supplying the (decimal) graphics mode number on the command line, for
- example:
-
- >CShow /71 to use mode 71 for 640x480 EGA
-
- The CompuShow Screen
- ====================
-
- The program will start by retrieving and sorting a directory of your disk
- files. The top three lines of the screen show the current date, day, a
- running time-of-day clock, and identify the directory display (eg. A:\*.* or
- C:\PICS\*.*). The center twenty lines of the screen contain the sorted disk
- file directory.
-
- Below the directory display is a prompt and input area. The input area is
- actually a forty-six character window over a sixty-three character field. The
- window will scroll to allow you to enter up to sixty-three characters.
-
- The bottom line of the screen is used to display "shift-status". The current
- status of the CAPS Lock, Insert, Num Lock, and Scroll Lock, as well as either
- shift key, Ctrl, or Alt key is indicated.
-
- [F1] for Help
- =============
-
- At the input field (or while in the directory display), press the [F1]
- function key to pop up a quick-reference Help Screen with a brief description
- of the options available.
-
- The Directory Display
- =====================
-
- The (initial) directory display "format" depends on the number of files
- displayed.
-
- Up to 40 files: The file name, size, date and time are displayed.
- The files are listed in two columns.
-
- 41 to 80 files: The file name and size are displayed.
- The files are listed in four columns.
-
- 81 to 120+ files: The file name is displayed.
- The files are listed in six columns.
-
- The program automatically selects a format to display as many files as
- possible on each screen. If you have more than one screen of files, you may
-
-
- Page 2
-
-
-
-
-
-
-
- display additional directory screens by:
-
- - In the input area: Press PgDn/PgUp.
-
- - In the directory display: Press Ctrl-PgDn/Ctrl-PgUp, or press the
- "up arrow" key at the first file or the "down arrow" key at the last
- file on the screen.
-
- Changing the directory display
- ==============================
-
- - At the input area, you may change to a different disk drive by typing the
- drive designation and pressing the [F2] key. For example, type "A:" and
- press [F2] to switch to drive A:.
-
- You may also change to a different sub-directory. Type the sub-directory
- name in the input area and press [F2]. The sub-directory specification can
- be any form acceptable in a DOS "ChDir" command, such as "\" or
- "..\..\OTHER". You can also combine a drive and sub-directory change, such
- as "B:\PICS".
-
- - Press [F3] to "toggle" between the "compressed" directory display (four or
- six columns) and a "wide" directory display (two columns, including the
- file name, size, date, and time.)
-
- - Enter a directory mask and press [F4]. For example, type "*.GIF" and press
- [F4] to limit the directory display to all files with a ".GIF" file name
- extension. Press [F4] with a blank mask to reset the directory mask to
- "*.*" to display all files.
-
- Selecting a file to display
- ===========================
-
- Method 1: Enter the name of the file
- ------------------------------------
-
- Type the name of any file and press <Carriage Return> to select it. Note that
- you may use this method to enter the name of a file that is not in the
- displayed file list (from a different disk or sub-directory.) Simply type the
- full name of the file, specifying the disk drive and sub-directory location,
- as needed (eg. "c:\pics\special\hidden\other.gif"). When you press <Carriage
- Return>, the file will be retrieved, or a "beep" will sound if it was not
- found.
-
- Method 2: Selecting from the directory list
- -------------------------------------------
-
- To select a file from the on-screen list of files, press the "up arrow"
- cursor key to move into the directory display. You may then move around the
- list of files using the cursor arrow keys, PgDn, PgUp, Home, and End. (While
- you are in the directory display, PgDn and PgUp take you to the bottom and
- top of the column. Ctrl-PgDn and Ctrl-PgUp display additional directory
- screens.)
-
- At the last file on the screen, the "down arrow" key will take you to the
- first file on the following screen. At the first file on the screen, the "up
-
-
- Page 3
-
-
-
-
-
-
-
- arrow" key will take you to the last file on the previous screen.
-
- Type a "letter key" (A..Z) to move to the next file starting with that letter
- (repeatedly typing "A" will move you to each file starting with the letter
- "A".)
-
- When you find a graphics file that you would like to display, press <Carriage
- Return>. (If you change your mind, press ESCape to return the cursor to the
- input area without selecting a file.)
-
- Once a file has been selected
- =============================
-
- The program will read and examine the file to see if it is a supported
- graphics file. The "demonstration" version of the program recognizes either
- CompuServe RLE or GIF graphics formats. The "enhanced" version of the program
- also recognizes Macintosh MacPaint files.
-
- If the file is not one of the supported graphics types, a box will pop up
- indicating that it is an unknown (or un-supported) file type. Press any key
- to make another selection.
-
- If the file is a supported graphics format, a box will pop up with
- information about the file and display options.

- RLE Graphics
- ============
-
- The RLE format supports "Medium" and "High" resolution graphics. The
- information box should indicate either:
-
- 192 rows of High Resolution RLE
- or
- 96 rows of Medium Resolution RLE
-
- One display mode is indicated (either CGA or Hercules.) (There is nothing to
- gain by displaying in an EGA mode, since RLE is "black and white", and looks
- best in 320 x 200 format.)
-
- - Type "1" to display the RLE image. (Display is instantaneous.)
-
- While the RLE image is displayed:
-
- - Press "I" to Invert the image. Some RLE images (radar/weather maps,
- for example) should be "inverted", which reverses black and white,
- before printing. Without inverting, you would print a black page with
- white lines.
-
- - With the enhanced program, you may print the image by pressing "P"
- (or ^P).
-
- - Type <Carriage Return> to return to the RLE information box.
-
- - At the information box, the image may be re-displayed by typing "1" again.
-
- - Type "0" (zero) (or <Carriage Return>) when finished with this file. The
- RLE information box will disappear and you will be returned to the main
- directory screen, ready to select another file to display.

- GIF Graphics
- ============
-
- The information box for a GIF graphics file will indicate the GIF signature
- and version. CompuShow version 5 supports GIF version "87a". If the GIF file
- is an unknown (future) version, you will hear a "buzzer" sound, and the GIF
- version will blink. The width, height, and number of colors in the image are
- also shown.
-
- The number of display options will depend on the type of display adapter and
- monitor that you are using:
-
- GIF display modes \ video display: Herc Cga Ega Ega-480 MCGA VGA
- +-------------------------------------------+----+---+---+-------+----+---+
- | 320x200 / 640x200 monochrome | Y | Y | Y | Y | Y | Y |
- | 320x200 4 color (4 palettes) | | Y | Y | Y | Y | Y |

- | 320x200 256 color MCGA | | | | | Y | Y |
- +-------------------------------------------+----+---+---+-------+----+---+
-
- - On all video displays, there are fifteen monochrome display modes assigned
- the letters A through O, where A is the lightest display and O is the
- darkest. (On an EGA/VGA display, you'll want to use mode "P" to display in
- monochrome.) The primary purpose for displaying a GIF image in a monochrome
- mode is to prepare it for printing, since images are printed WYSIWYG ("What
- You See Is What You Get".)
-
- - If the image is 320x200 (or smaller) you will also see a "Zoom" option on
- EGA/VGA systems, to Zoom the image to 640x400. Images displayed in this
- mode will have much "truer" colors than when displayed in 320x200x16 color
- mode.
-
- You may display the GIF image in ANY MODE LISTED (the PC-jr/Tandy modes will
- not work on all systems.) The "recommended" modes will be highlighted, the
- "inappropriate" modes will be listed in a dim text color.
-
- This "recommendation" is based on the width and height of the image compared
- to the physical screen dimensions in each mode. For example, if you display a
- 320x200 image in EGA 640x200 mode, the image will be "compressed" in the left
- half of the screen. NOTE, HOWEVER, THAT IMAGES LARGER THAN THE PHYSICAL
- SCREEN MAY BE PANNED, as described below.
-
- - Type the number (or letter) to display the GIF image in that mode.
-
- As the GIF image is being displayed, press ESCape or Ctrl-C to interrupt
- (and abort) display of the rest of the image. (The partial GIF image will
- remain on the screen. Type <Carriage Return> to return to the GIF
- information box.)
-
-
-
- Page 6
-
-
-
-
-
-
-
- While the GIF image is displayed:
-
- - On an EGA/VGA monitor, you may adjust the appearance of the COLOR or
- MONOCHROME image, as described below.
-
- - Images larger than the PHYSICAL SCREEN can be "panned", using the up,
- down, left and right cursor arrow keys. Press a key (once) to pan in
- that direction. Panning will stop at the end of the image, or may be
- interrupted by pressing any key. (Note that the down arrow key pans
- down, while "2" selects color 2, as described below. You may need to
- turn NumLock off to use your cursor keys to pan.)
-
- - The EGA/VGA display pans both vertically and horizontally, and can
- accommodate 16 color images up to 320x1638, 640x819, or 1024x512.
-
- - The CGA display pans both vertically and horizontally, and can
- accommodate 4 color images up to 640x400, and monochrome display
- of images up to 640x800.
-
- - The Hercules display pans vertically to accommodate images up to
- 640x800.
-
- - With the enhanced program, you may print an image displayed in
- monochrome (one of the lettered modes) by pressing "P" (or ^P).
-
- - Type <Carriage Return> to return to the GIF information box.
-
- - At the information box, you may re-display the GIF image in the same or a
- different mode by typing the number or letter corresponding to the desired
- mode.
-
- - Type "0" (zero) (or <Carriage Return>) when finished with this file. The
- GIF information box will disappear and you will be returned to the main
- directory screen, ready to select another file to display.
-
- Adjusting a COLOR EGA/VGA image
- -------------------------------
-
- You can adjust the colors of an image displayed in EGA/VGA modes 7, 9, or Z:
-
- Most images look "quite good" on an EGA/VGA monitor. The GIF file contains a
- "color map" which is used to select sixteen colors from the palette of sixty-
- four. However, adjusting the colors will frequently result in a more pleasing
- image. This is particularly true where skin tones are concerned.
-
- The sixteen colors displayed are numbered 0 to 9 and A to F. Color zero is
- always the background. To select a color to adjust, type the color number
- (0..9 or A..F). That color will flash three times, so that you can see where
- it is on the screen and decide whether it should be adjusted. There are two
- methods for adjusting colors:
-
-
-
-
-
-
-
-
- Page 7
-
-
-
-
-
-
-
- - A selected color may be adjusted by increasing or decreasing the Red,
- Green, or Blue component:
-
- RED: decrease [F1] [F2] increase
- GREEN: decrease [F3] [F4] increase
- BLUE: decrease [F5] [F6] increase
-
- Each color has a Red, Green, and Blue component with a "weight" of 0..3, so
- pressing [F2] four times will step through all four levels of Red.
- [ 4 (Red) x 4 (Green) x 4 (Blue) = the palette of sixty-four colors. ]
-
- - You may "step through" all sixty-four colors in color number sequence:
-
- COLOR NUMBER: decrease [F7] [F8] increase
-
- The adjusted palette may be saved to disk by pressing Alt-F10 (hold the Alt
- key and type the [F10] function key.) The palette is saved in a file with the
- same "base" file name as the GIF file, and a "CSH" extension. (The palette
- for GIF file "PUPPY.GIF" will be saved in "PUPPY.CSH".)
-
- Whenever the GIF file is displayed in EGA or VGA mode (7, 9, or Z), you may
- retrieve the saved palette by pressing [F10]. The colors will instantly
- change to your adjusted palette. (If the palette file is not found, the
- program will "beep".)
-
- To return to the original color palette as defined by the color map in the
- GIF file, press [F9].
-
- Pressing [F9] and [F10] will allow you to instantly review the differences
- between the original GIF palette and your adjusted palette.
-
- A NOTE about GIF images with more than 16 colors
- ------------------------------------------------
-
- CompuShow will display GIF images containing more than 16 (typically 32 or
- 256) colors on the EGA/VGA in a quality comparable to a sixteen color image.
- In analyzing the color map, the program "compresses" it to remove colors
- which are equivalent on the EGA/VGA. Surprisingly this process usually
- results in a color palette containing 9 to 14 colors. (This means that you
- are losing some subtle color shading present on the original computer.) When
- adjusting the palette, as described above, you can determine how many
- discrete colors there are, since the program will "beep" when you reach a
- color number beyond the number of colors in this "compressed" palette. (If
- you type "9" and the program beeps, then there are only nine (0..8) colors in
- the compressed palette.)
-
- Adjusting a MONOCHROME EGA/VGA image
- ------------------------------------
-
- Mode "P" displays an image in EGA/VGA monochrome. To adjust the "brightness"
- of the image (in preparation for printing it), press the PgUp key to make it
- brighter and the PgDn key to make it darker.

-
- MacPaint Images (ENHANCED PROGRAM)
- ==================================
-
- The information box indicates the number of rows in the MacPaint image. Each
- image is 576 wide, and a maximum of 720 long. The image may be displayed in
- Hercules 720 x 348 B&W, CGA 640 x 200 B&W, or in EGA 640 x 350 B&W mode.
-
- - Type the number to display the MacPaint image in that mode. (Display is
- instantaneous.)
-
- MacPaint images are usually longer than Hercules, CGA, or EGA screens.
- During display:
-
- - The up and down arrow keys allow you to "pan" a single row at a time.
- - PgUp and PgDn pan the image in about 20 steps.
- - Ctrl-PgUp and Ctrl-PgDn pan in about 5 steps.
- - Home and End jump immediately to the top and bottom.
- - Ctrl-Home and Ctrl-End "auto-pan", so that the image moves slowly up
- or down the screen until the top or bottom is reached, or until a key
- is pressed to stop the "auto-pan."
-
- - On an EGA/VGA monitor, you may press "C" during the display to
- "colorize" the image. The 576x720 image (larger than the screen) is
- compressed to 288x350, so that it may all be displayed on one screen.
- Shades of reds and browns are displayed in place of the black and
- white image. The [F1]..[F10] function keys will allow you to select
- any of ten different pre-defined color palettes.
-
- Press any key to remove the colorized image.
-
- - With the enhanced program you may print the MacPaint image by
- pressing "P" (or ^P).
-
- - <Carriage Return> returns you to the Information box.
-
- - At the information box, the MacPaint image may be re-displayed by typing
- the number of the desired display mode.
-
- - Type "0" (zero) (or <Carriage Return>) when finished with this file. The
- information box will disappear and you will be returned to the main
- directory screen, ready to select another file to display.

- Printing (ENHANCED PROGRAM)
- ===========================
-
- The IBM-PC has become a standard in the personal computer world over the past
- several years. The "IBM compatible printer", however, is not as clearly
- defined. As a matter of fact, IBM itself has several different "standard
- printers" capable of printing graphics. In view of this "non-standard
- standard", CompuShow uses custom graphics printer drivers, for various
- printers.
-
- The supplied printer drivers are described in detail in PRINTERS.DOC
- (included with the enhanced program.)
-
- Selecting a printer driver
- --------------------------
-
- Most "IBM compatible" printers (such as Epson, Citizen, Panasonic, Star,
- Toshiba, etc.) can use the IBM Graphics Printer driver "IBMGRAPH.DRV".
-
- ------------------------------------ NOTE -----------------------------------
- If your printer has a "quad-density", 240 dots/inch mode, selected with
- ESCAPE,'Z', (eg. IBM Pro-Printer) try GENERIC.DRV for improved printing of
- MacPaint images and 350 line GIF images.
- -----------------------------------------------------------------------------
-
- To determine whether a driver will work with your printer, start CompuShow
- with the name of the driver, for example:
-
- CSHOW IBMGRAPH
-
- and press <carriage return>. When the program starts, the printer driver will
- be loaded from the same disk and sub-directory as CSHOW.EXE (or the program
- will display a message, indicating that the driver could not be found.)
- Display an RLE or MacPaint image, or a GIF image USING ONE OF THE LETTERED
- (MONOCHROME) DISPLAY MODES, and press "P" to print.
-
- - When a printer driver has been loaded, a "P to print" reminder is displayed
- on the RLE and MacPaint graphics screens, and in the GIF information box.
-
- - If no driver was loaded, the "P to print" message is not displayed, and
- pressing "P" causes the program to "beep".
-
- - RLE and GIF images are printed "sideways" on the page. MacPaint images are
- printed "right-side-up".
-
- - The print routine for GIF images is automatically selected, based on the
- length of the GIF image. The program will select a 200 line, 350 line, 480
- line or 576 line print mode.
-
- - Press any key to interrupt (and terminate) printing.
-
-
-
-
-
-
-
-
- Page 10
-
-
-
-
-
-
-
- - When the image has finished printing (or when it has been interrupted by a
- key-press) a form-feed will be sent to the printer. If your printer doesn't
- advance to the top of the next page, you probably need to set top-of-form.
- If your printer doesn't have a specific button to set top of form, you may
- need to turn it off, re-position the paper, and turn it back on.
-
- In most cases (see PRINTERS.DOC), images may also be printed in a "single-
- density" mode for high speed printing by pressing ^P (Ctrl-P) instead of "P".
- (Hold the Ctrl key down and type "P".)
-
- If the IBM Graphics Printer Driver doesn't work with your printer, check
- "PRINTERS.DOC" for a description of other printer drivers.
-
- Setting up a "default driver"
- -----------------------------
-
- When CompuShow starts, it will look for a printer driver named "CSHOW.DRV"
- (on the same disk, in the same sub-directory as CSHOW.EXE)
-
- COPY IBMGRAPH.DRV CSHOW.DRV
-
- to make a copy of the IBM driver with CompuShow's default name. Now, you can
- start CompuShow without a driver name and CSHOW.DRV will automatically be
- used.
-
- Custom Printer Drivers
- ----------------------
-
- We want all users of the enhanced program to be able to use the print
- feature. IF NONE OF THE SUPPLIED PRINTER DRIVERS WORKS WITH YOUR PRINTER, we
- will provide ONE custom printer driver AT NO CHARGE! (See PRINTERS.DOC)
-
- NOTE that CompuShow will only print in black and white. A custom driver for a
- color printer WILL NOT print in color, since the program passes "on or off
- pixel" information to the driver.
-
- Quitting CompuShow
- ==================
-
- At the main directory screen, press ESCape to exit the program and return to
- DOS.

-
- Installing Screen Colors and System Configuration (ENHANCED PROGRAM)
- ====================================================================
-
- At your DOS prompt, type CSHOWI (and a carriage return.)
-
- There are nine color settings, in four areas:
-
- - SCREEN TOP colors are used for the top three lines of the screen and
- for pop-up boxes. You specify a background color, normal and hilight
- text colors.
-
- - SCREEN CENTER colors are used in the center of the screen. Again, you
- specify the background color, normal and hilight text colors.
-
- - INPUT FIELD colors are used in the input area, and for the "highlight
- bar" that you move through the directory list.
-
- - BORDER COLOR is the color of the screen border. (Hercules, EGA, and a
- number of CGA adapter/monitor combinations WILL NOT display the
- border color. "Standard" CGA adapter/color monitor combinations
- will.)
-
- In the lower half of the screen, all combinations of background and text
- colors are displayed. Background colors are identified with the numbers 0..7,
- and text colors with the letters A..P.
-
- You make your selection for each of the nine colors in the top half of the
- screen. At each of the nine specifications:
-
- - Press carriage return to leave the color unchanged and move to the
- next field.
-
- - Enter the letter or number of the color and press carriage return to
- move ahead. As you change any color, the screen is updated
- immediately.
-
- - Press TAB to move back to the previous color specification.
-
- - Press ESCape to exit the color install, ABANDONING any changes.
-

-
-
-
-
- Page 12
-
-
-
-
-
-
-
- After you complete the selection of screen colors, you move on to System
- Configuration, which allows you to specify:
-
- - The type of 480 line EGA you have (or "none"). Specifying a 480 line EGA
- makes it unnecessary to use the "/" command line switch for either
- CompuShow or the Slide Show program.
-
- - If you need to force to MCGA or VGA mode, you can specify the mode here,
- making the "+" command line switch unnecessary.
-
- - You may specify a drive and sub-directory to be selected automatically
- when the program starts. For example, let's assume you usually start the
- program and then switch to "c:\graphics\gif" using the [F2] key. You can
- enter "c:\graphics\gif" in the System Configuration, and it will be
- selected automatically.
-
- - You may specify a directory mask to be selected automatically. If you
- usually change the directory mask to "*.GIF" using the [F4] key, you can
- specify that mask in the System Configuration, and it will be set for
- you, when the program starts.
-
- - You may similarly specify the "two column" directory display, if you'd
- like it selected automatically at program start-up.
-
-
- When you press carriage return at the end of System Configuration, the
- configuration is saved in CSHOW.CFG, which both CompuShow and the Slide Show
- program will use. (Both programs will look for it in the same sub-directory
- as the program.)

- CompuShow Slide Show (ENHANCED PROGRAM)
- =======================================
-
- Execute the program by typing CSHOWS (and a <Carriage Return>) at your DOS
- prompt. (NOTE that the command line switches and System Configuration
- described for CompuShow also apply to the Slide Show.)
-
- The Slide Show program displays RLE, GIF, and MacPaint images in the same
- display modes available in CompuShow. Since it is essentially an "automatic
- CompuShow", start planning your slide show by making some notes while in
- CompuShow. You will need the name of each graphics (RLE, GIF, or MacPaint)
- file and the appropriate display mode (the number or letter key used to
- display it.)
-
- When CShowS starts, it reads the slide show instructions from a "script"
- file, "CSHOWS.SCR", located on the current disk and sub-directory. If you
- have several scripts, you can specify that a different script file should be
- used:
-
- >CShowS (script file "CSHOWS.SCR")
- >CShowS b (script file "b.SCR")
- >CShowS b. (script file "b")
- >CShowS .b (script file "CSHOWS.b")
- >CShowS b: (script file "b:CSHOWS.SCR")
- >CShowS b:b.b (script file "b:b.b")
-
- In other words, you can "over-ride" (any or all of) the location, file name,
- or extension.
-
- The script file is an ASCII (text) file, which you create using a word
- processor or text editor program. Word processor programs usually have the
- ability to save the file (document) in ASCII or "un-formatted" mode. (Be sure
- to do this!)
-
- [ Three example script files are included, which will run a slide show of
- all graphics files (RLE, MacPaint, and GIF) included on the program disk:
- >CShowS Herc (script file HERC.SCR)
- >CShowS Cga (script file CGA.SCR)
- >CShowS Ega (script file EGA.SCR)
- for display on Hercules, Cga, and Ega systems. Use one (or more) of these
- script files as examples while reading the instructions, below.]
-
- Each slide show "command" is on a separate line. The first character in the
- line specifies the type of command (UPPER and lower case letters are
- equivalent):
-
- F: The File name; the name of the RLE, GIF, or MacPaint file. You may include
- the disk drive and/or sub-directory name, as needed. CShowS reads and
- analyzes the file to determine what type of graphics file it is. If the
- file is not found, or if it is not a graphics file, the program will
- "beep".
-
- M: The display mode. This is the number or letter key that you would press to
- display the image in CompuShow. CShowS displays the image in this mode. If
- the specified mode is un-available on the current computer, the program
-
-
-
- Page 14
-
-
-
-
-
-
-
- will "beep". (A script containing EGA display modes will not run on a CGA
- or Hercules machine, for example.)
-
- In addition, you may display an "inverted" RLE image by specifying mode
- "I", and a colorized MacPaint image by specifying modes "A" through "J" to
- correspond to the ten color palettes selected with the [F1] through [F10]
- function keys.
-
- P: A pan. MacPaint images may be panned Down and Up. GIF images may be panned
- Down, Up, Right and Left.
-
- D: A delay, in seconds, from 1 to 30. (Multiple "D" lines may be specified,
- if you want more than a 30 second delay.)
-
- W: Specifies a "Wait for key press". CShowS will wait for a key to be pressed
- before proceeding.
-
- Q: Is the "Quit" command. CShowS will quit, rather than repeating the slide
- show.
-
- For a "free-running" slide show, you would use "F", "M", "P" and "D"
- commands. The program will start over when it reaches the end of the script.
- You exit the program by pressing a key. (If an image or delay is in process,
- it will finish before the program terminates.)
-
- By placing a "Q" command at the end of the script, the slide show will run
- one time and then quit. (It may be interrupted with a key press, if desired.)
- By using wait (W) commands, instead of delay (D) commands, you can set up an
- "operator controlled" show, where the program waits for a key press between
- images. (Pressing ESCape, Ctrl-C, or PgDn will exit the program at a "Wait".)
-
- An example: (CShowS.Scr)
-
- Fradarmap.rle
- M1
- D1
- Mi
- D1
- Flarge.gif
- M2
- D1
- Pd
- Pr
- Pu
- Pl
- Fb:\macs\mickey.mcp
- M2
- Pd
- D1
- Md
- D2
-
- In this example, we first select "RADARMAP.RLE", display it in mode 1 (CGA)
- and delay 1 second. We then display it "inverted" (note that no new "F"
- command was specified, so we're working with the same file), and delay 1
- second.
-
-
- Page 15
-
-
-
-
-
-
-
-
- Next we select "LARGE.GIF", display it in mode 2 (CGA 320x200, Palette 2) and
- delay 1 second. This GIF image is both wider and longer than the 320x200
- screen, so we pan down, then right, then up, and then left.
-
- Next we select "MICKEY.MCP" which is located on drive B: in sub-directory
- "MACS", display it in mode 2 (EGA), pan down to the end, and delay 1 second.
- We then "colorize" it, using the [F4] palette, by specifying mode "D", and
- delay 2 seconds.
-
- Since there is no "Q" (Quit) command, the slide show will repeat until a key
- is pressed.
-
- Compatibility with earlier scripts
- ----------------------------------
-
- Scripts written for earlier versions of the CompuShow Slide Show will need to
- be "translated" to the display modes used by Slide Show Version 3 (CompuShow
- Version 5).
-
- Version 1 Version 2 Version 3
- CGA 320 x 200 Palette 1 1 1 1
- CGA 320 x 200 Palette 2 2 2 2
- CGA 320 x 200 Palette 3 3 3 3
- CGA 320 x 200 Palette 4 - 4 4
- EGA 320 x 200 x 16 colors 6 7 5
- EGA 640 x 200 x 16 colors 7 8 6
- EGA 640 x 350 x 16 colors 8 9 7
- MCGA 320 x 200 x 256 colors - - 8
- VGA 640 x 480 x 16 colors - - 9
- PcJr 320 x 200 x 16 colors 4 5 X
- PcJr 640 x 200 x 4 colors 5 6 Y
- EGA/VGA "Zoom" - - Z
-
- You may (eventually) want to change Version 1 and 2 scripts to the new mode
- numbers. However, TO USE A PRIOR VERSION SCRIPT WITHOUT CHANGING IT, start
- the program:
-
- CSHOWS -1 (to use a version 1 script)
- CSHOWS -2 (to use a version 2 script)
-
- NOTE that earlier versions of the Slide Show automatically pan MacPaint
- images when displayed in mode 1 or 2. Panning is no longer AUTOMATIC. You'll
- need to specifically insert pan commands in the script.
-
- ALSO, unlike earlier versions, the Slide Show now uses the adjusted palette
- for EGA-GIF images. (If you have adjusted the colors of a GIF image and saved
- the palette with Alt-F10, those colors will be used in the Slide Show.)

- =================
-
- CompuShow is copyrighted software. However, you are encouraged to copy and
- share CompuShow with others according to the following requirements:
-
- CompuShow program(s), User's Guide, and any associated files may be
- freely copied and shared as long as ALL FILES ARE INCLUDED. This
- requirement is emphasized as a result of "stripped down" versions
- of the program(s) appearing on some bulletin board systems.
-
- The Demonstration Version (5.00a) may be copied and shared, so long as no
- charge is made for the software. The demonstration version includes the
- CompuShow program and (this) User's Guide. The program and User's Guide must
- be distributed together. They may be distributed via modem from bulletin
- board systems provided that both files are transmitted (archived) together.
-
- The Enhanced Version (5.00b) diskette with all files may be freely copied
- and shared with others, so long as no charge is made. The files may be
- distributed via modem from bulletin board systems, provided that ALL FILES
- are transmitted (archived) together. No files on the disk may be distributed
- unless all files are included.
-
- WHY SHAREWARE?
- --------------
-
- A few years ago, we advertised a (much simpler) program in a national
- computer magazine. Our advertising cost was so high that, even with a retail
- price of $45, we never reached "break-even"! The ShareWare concept turns
- CompuShow into its own ad! Our costs are reduced, and we can price the
- program accordingly.
-
- ShareWare let's you "try it before you buy it"! You can determine whether a
- program works properly and how easy it is to use, before you pay for it.
-
- WHY REGISTER?
- -------------
-
- Since CompuShow is a ShareWare product, we don't receive a penny when you
- download it from CompuServe or a Bulletin Board, or receive it on a disk of
- ShareWare programs.

- Since version 1.7 was released in July 1987, we have continued to improve
- and enhance the program, and have completed five new versions. Most of the
- enhancements were suggested by our registered users, and most of our
- registered users have upgraded as new versions are announced. They like
- CompuShow and the improvements that their registration fees have made
- possible!
