    it works but too slow. if you don't have the same computer the NASA does have, you would not want to run this 10 DEFDBL A-Z:PRINT TIME$:FOR A=1 TO 1000000! 20 B=B+1/A:NEXT A:PRINT TIME$, B it will take almost 10 minutes. i have yet windows xp 64 and 3.3 ghz the same program runs in amstrad basic2 (you have to remove the "defdbl a-z") in 20 sec. unfortunately i don't know all basic commands but! i would like have a basic that does ASIN and ACOS because the tan(x) may lead to trouble i can't tell anything about support because i did not ask for it. one advantage is there is no "coordinate outside virtual screen" error which causes more trouble in amstrads locomotive basic

    Well, I tried to run TERM.BAS (The terminal emulator written in BASIC) on MacOSX, it fails when trying to open COM1: but the PCBASIC program, doesn't allow you to map a port, if for some reason you desired to use the serial ports." (TERM) - Terminal Emulator Device Unavailable in 140 Ok  list 140 140 CLS:PRINT ID$:CLOSE:OPEN"COM1:,,,,CS,DS" AS 1:CLOSE

    Would be great if it could be installed to a standard directory and started from anywhere.
