This is a program that I wrote about 31 years ago and was my first "Shareware" type of program.
The really cool thing about this program is that this was the one I learned C with - and subsequently learned every other language that I've learned by taking pieces of this one and rewriting it because I knew it so well.
I hate the bracing style I used in this. This is probably the 14th reformat overall, and was when I was in my "Petzold, Programming Windows 3.0" stage. The bracing style is awful. I should have stuck with K&R style bracing, which is what I do now.
I wound up donating this to the FreeDOS project in July of 2001. Unfortunately, the only record I can find of this now is this spanish version of the FreeDOS log.
Aside from the bracing style - I hope you enjoy looking at this. I found it while rummaging through the house over the last week and thought I would publish it on Github - not because its useful, but because it is historical.
The time this was written was a great time, when someone like me could just start publishing software on bulletin boards.
Trust me, at the time it was cool.
See the DOCS directory for some other cool historical documentation, including a software review.
Cool thing is, I made $10 off of all the hours that I put into this. Yes, $10.
This now builds with the OpenWatcom C Compiler for DOS. The default makefile (Makefile) will build the DOS executable.
Building this software also requires the A86 assembler by Eric Isaacson. Install the software in a directory that appears in your path.
After installing the above and the the Watcom C compiler setting up your environment, just type wmake
