C programmers are expensive, and the readin.c code is ancient. At first
I couldn't understand it at all: Then I remembered that back before
maybe 1983, C arguments were listed rather than prototyped: Like the
program in your link. Meanwhile, this code makes tremendous use of goto,
a 1940's thru early 1970's technique to save stack when you might have
only 256bytes or 1K RAM. To add insult to injury, the indentation
appears to be all over the place. You don't need just any C programmer:
You need a spaghetti programmer from the 1960's.

You can easily rewrite this program in Python. Because the program
(appears to) operates on human keystrokes, even the slowest interpreted
language is more than fast enough to keep up with the fastest typist in
the world.

If you're wondering how to take raw keystrokes, not requiring an Enter
key press, in Python, download my UMENU2 from , look in file for method (function) getch_unix(), which reads raw
keystrokes without requiring an Enter.

I read later in the thread that you got your program to work. That's
good, for now, but the code is old and ugly, and sooner or later you'll
need to replace it.

What does that program do, anyway? The code was so whack I couldn't
