I've been working on an ANS Forth port of a classic, nearly 30 year-old game,
called "Super Star Trek". It was originally written in BASIC in the late 70's by
Mike Mayfield, and subsequently enhanced by others. This game has been ported to
many different languages, but I did not find a version in Forth. A "beta"
version of my port to ANS Forth may be found on the kForth Programming Examples
Page:
http://ccreweb.org/software/kforth/kforth4.html
See the file strek.4th.
Very simple modifications need to be made to the first two lines of code to run
on a vanilla ANS Forth system. For example, see the file strek.fs in
ftp://ccreweb.org/software/gforth/
I've already spent more time on this than anticipated. At this stage, the only
way to shake out bugs is for people to try it out!
Cheeers,
Krishna Myneni

This won't work on normal Forths. Make that FVARIABLE fdum :-)
Global comment: A pity that you left the ALL UPPER CASE help
and abbreviated commands in. It may appeal to people who remember
this game from their youth, but IMHO it unnecessarily blemishes a
rather nice looking game for first timers.
Don't ask me how it plays, I have absolutely no patience for games :-)

It *shouldn't* work on any Forth where 1 FLOAT is not equal to 1 CELL, which
includes kForth! I guess it takes a while to cause a problem... Thanks. That
certainly needs to be fixed!

Actually, the help is not upper case; only the short list of command
descriptions. And, yes, I left it like that for historical reasons.

Meanwhile, I might have found another one:
command> com
Computer active and awaiting command (0 TO 5, OR -1) ?
Caught exception 0xc0000005
( I pressed "?" for help )

Well, it's essentially done. The game plays fairly well. There may be a few
rough spots in the code, where the output needs tweaking. Otherwise, the task is
just about finished.
I'm glad the program brought back memories. I was never much into computer
games, but I remember having played this one a few times in my younger days.

I notice that the kforth Win distribution contains no executables
and the user is required to recompile from source.
IMO, that's a big ask. Win users are unlikely to know anything
about Cygwin, or gcc, or Linux, or the specific tools and libraries
needed to do the job. When even the first step fails (running
the downloader from www.cygwin.com and crashing) then it's
clearly time to give up :)

expected to know how to do it. This isn't true in Windows.
If you DID distribute a binary version of kforth you'd have to
distribute at least somr of the Cygwin DLL's which it uses.
IIRC when I DL'ed kforth I had CYGWIN installed but I needed one more
Cygwin package to get it to compile, readline.
