- Documentation for
- FUNCOLRS.COM
- by Duane Paulson
- BASED ON RNDGEN.ASM
- BY COMPUSERVE MEMBER 72210,17
-
- First off, a big thank you to CompuServe Member 72210,17. I don't know your
- name, but you uploaded RNDGEN.ASM way back in July of 1988. Without it,
- Funcolrs probably wouldn't work half as well. RNDGEN.ASM implements what looks
- like a very sophisticated psuedorandom number generator, certainly beyond
- anything that I could come up with.
-
- FUNCOLRS.COM is for ZCOMM and PRO-YAM users, who can use it to modify the
- colors on their graphics transfer screens. GSZ users, regretably, cannot use
- this program, because the GSZ color variables are stored within the GSZ
- executable.
-
- What FUNCOLRS does is set each variable to a different color. Since there
- are 15 active variables in the GCOLORS set (the last 2 don't appear to be
- in use), and there are 15 colors available under DOS (if you don't count
- black, and include the high-intensity values) everything works out. Each
- color parameter is assigned a unique value. All the values from 1 to 15 are
- used once, and only once. Since a random number generator is in use,
- however, you never know which colors are going to end up assigned to which
- parameters. It is my opinion that this adds to the fun of using a color
- graphic file transfer program. You will never know what your screen will
- look like until the file transfer starts. Since all the values are for
- a unique color on a black background, everything should be readable. The
- only exception could be mono monitors that don't display "bright black"
- (DOS color 8).
-
- You can implement FUNCOLRS by a two step process:
- 1. Place it in your ZCOMM start-up batch file (or call it
- from your start-up script!)
- 2. Put the following line in your ZCOMM start-up script:
- source gcolors.t
- Your installation is now complete.
-
- FUNCOLRS will run automatically, and select a new set of colors each time
- you run ZCOMM. If you should hit on a combination of colors that you want
- to keep around for awhile, just set the read only bit on GCOLORS.T before
- running ZCOMM again (C>attrib gcolors.t +r). FUNCOLRS will not be able
- to write to the file. It will show you an error message,
- "Cannot create file. No handles available or access denied."
-
- FUNCOLRS creates GCOLORS.T in the subdirectory it is run from, so you'll have
- to install it in you ZCOMM directory, or point the script toward it when you
- issue the source command.
