I didn't know how to report a bug to the GW-BASIC folks, but TK Chia hangs out on this list, so I thought I'd mention it here.
I noticed TK Chia released a new GW-BASIC the other day. I started playing around with it, just writing a few simple BASIC programs. I think I found a bug: RND(1) should always generate new random numbers. GW-BASIC resets the sequence every time you RUN a program. So you were supposed to seed the random number generator with the RANDOMIZE statement, passing a value as the seed. To have RANDOMIZE use an internal timer as the seed, you can add the TIMER keyword: RANDOMIZE TIMER But this GW-BASIC seems to treat "TIMER" as a variable, so it's the same as typing: RANDOMIZE 0 or any uninitialized variable: (which are set to zero) RANDOMIZE VAL However, a workaround is to use the value from the system time (TIME$) and use only the seconds. You can do that with the MID$() function. LET SEED = VAL(MID$(TIME$,7,2)) That picks up only the seconds from the system time. I found a copy of the GW-BASIC manual at https://hwiegman.home.xs4all.nl/gw-man/
