Is there any way I can get my program to wait, say, 1.2 seconds? QB 4.5 has a
command SLEEP, that pauses for n seconds, but I need something more accurate.

With SOUND command I could generate intervals with 1/18 sec accuracy, but that
has a nasty side effect: beep from the speaker. If only could I set the
frequency low enough, the beep wouldn't be generated (my 4DOS has this
advantage (freq<20Hz)), but no: QB stops with error when frequency is set 
under 37 Hz.

So, what I'd want is a mean of generating pauses at least with 1/10 sec
accuracy, preferably 1/100 (but even 1/18 is OK) with my QB 4.5. Or do I
have to change my compiler to something more 'state-of-the-art' one?

Try the TIMER function.  Returns a real, good to 2 decimals.  The fractional
portion is the 1/18ths part.
