I posted a nice PowerBASIC demo in the file
http://www.tkk.fi/~ajy/STPB.BAS
done with the PowerBASIC Console Compiler.
The Star Trek game was there in almost all timesharing installations
in the 1960's and the 1970's, and it still was popular in the early
BASIC era of personal computers in the beginning of the 1980's.
I converted it to the PB/CC as my (second) exercise in the use of the
PowerBASIC to get my hands wet so to speak. I have seen that the PB
is indeed much better than the freeware BASICs.
If someone around here is interested in computer games -- enjoy!!!
