/F???1 Display file size (default=1)
/G<mode> Graphics mode for the display. /G320x200x16
/H or /? Display help screen with these switches listed and exit.

/K<n> Determines if GIF89a comment records are automatically viewed
after viewing in single view mode. The default is ON (1).
/L<n> Sets the label on/off switch for array generation.
/N<template> Sets the "printf()" style template for filenames generated
by GDS when array files are written. GDS%03d = GDS000.GIF.
/O<n> Slide show sort flag /O0 = no sort (default), /O1 = sort.
/P<n> Automatic Array generation if n=5 then the array will be 5x5.
/Q<x>_<y>_path\filename.GIF Auto insertion of logo in arrays.
/R<n> Sets the default "LOck/AutO" mode (/R0=AutO, /R1=LOck).
/S<n> Specifies automatic slide show mode. See the "@<FILE>" option.
/T<mode> Text mode of the display. The default value is /T80x25.
/V<n> File directory mode (/V0=vertical, /V1=horizontal list).
/W<n> 1 = Auto write of generated arrays, default setting is OFF (0).
/X Leave last image on screen when exiting slide show.
/Z<n> n = number of 100ths of seconds to delay between slides.
The default value is 5 seconds (500).
/<NAME> Forces GDS to assume it has the named video card. USE WITH CARE.
>> You should NOT have to do this except for some Paradise or Oak cards. <<
The following video cards are currently defined:
/EGA Standard EGA or fully compatible
/VGA Standard VGA or fully compatible
/AHEAD Ahead Systems Chipset (type A)
/AHEADB Ahead Systems Chipset (type B)
/ATI ATI VGA Wonder
/CHIPS Chips and Technologies Chipsets
/EVEREX Everex Systems
/GENOA Genoa 6000 series
/OAK Oak Technologies
/ORCHID Orchid Technologies
/PARA Paradise Systems
/TRIDNT ATI Prism Elite (Trident Chipsets)
/TSENG Tseng Laboratories Chipset
/TSENG4 Tseng Laboratories Chipset (4000 series)
/VESA Standard VESA BIOS Interface
/VID7 Video Seven VRAM or FASTWRITE VGA
/ZYMOS Zymos HiRes 512K VGA
/512 Forces support for 512K of video RAM.
/1M Forces support for 1 meg of video RAM.
@<FILE> Reads a list of image files from <FILE>. Usually used for
automatic slide shows (see "/S").
The format of the video modes in the GDS.CFG file is as follows:
A, B, C, D, E, F, G, H, I, J ;optional comment
A) Name of the video card
B) Horizontal screen resolution (number of columns)
C) Vertical screen resolution (number of lines)
D) Number of bits per pixel (or 0 for text mode)
E) AX register on INT 21h call to set video mode (see I)
F) BX register on INT 21h call to set video mode (see I)
G) CX register on INT 21h call to set video mode (see I)
H) DX register on INT 21h call to set video mode (see I)
I) This option has one of three meanings:
1) 0 if video mode is a standard graphics mode
2) 1 if video mode is directly programmed (VGA register compatible
cards only!
3) The base address of the screen if the video mode is a text mode
(indicated by 0 bits per pixel).
J) Dot Mode (0=normal, 1=ATI 16-color chunky, 5=32k color mode.)
>> This version does NOT support the 16 million color format <<
To specify automatic command line options, add lines to GDSUSER.CFG
similar to the following examples:
AUTO, /e1 /t132x44 ;Turn auto-fit on, set text to 132x44
AUTO, /g800x600x8 /f?111 ;set RES: to 800x600x8, res, bits, size in dir.
AUTO, /PARA ;for Paradise board
AUTO, /512 ;for more than 256k of ram
NEW! NEW! NEW! NEW!
Demo version supports command line slide show options for users
that wish to use GDS to display images for their clients without
worrying about registering.
NEW! NEW! NEW! NEW!
Move the mouse cursor to the top of the screen while viewing an
image then hold down the mouse button to access the pull-down menus.
(gee, It looks like a game from Sierra!).
>> Do NOT do this when generating arrays. <<
NEW! NEW! NEW! NEW!
Ctrl-P will allow you to define a new palette for the GDS index
screen. If you define a new one that you really like, please send us
your GDS_TEXT.PAL file so that we can add yours to the default
options.
NEW! NEW! NEW! NEW!
Arrays generated by GDS 2.0 or higher and are saved as a GIF are
in the 89a format and contain additional data.
When you view one of the new arrays and "click" on an image in
the array, GDS will display the full screen image if it can find the
original file. If your arrays have the same name and are sequentially
numbered as in "CDROM001.GIF","CDROM002.GIF",etc you may use PgUp
and PgDn to brouse through them.
NEW! NEW! NEW! NEW!
GDS 2.x or higher now has full VESA support for the new S3 based
video cards. As usual anything new always adds new problems. Some
cards proclaim VESA support in the ROM bios but do not really work.
If you are having a problem then add the "/NOVESA" switch.
Another problem is that some of the new cards have support for
the 32k c
