Not tested, but I did do plenty of testing on the PLAY WAV command, and never had that hanging problem - I THINK it is coming from the fact that you are calling your sub from the PLAY WAV command, and MMBASIC is interpreting that as passing an array via the () syntax, so it tries to call WAVEND as a sub, but also tries to treat that as passing an array at the same time, and crashes.

I might have that wrong, but that is how I interpret it anyway. I would be very interested to know how you go if you remove the ().....

Smoke makes things work. When the smoke gets out, it stops!

START {OK}
PLAY FILE {OK}
START BLINKING LED {OK}
FILE PLAYBACK ENDS {OK}
LED STOPS FLASHING FOR ONE SECOND OR SO THEN STARTS AGAIN {OK}
[/Code]

This may be normal - I never tested the time it takes for MMBASIC to return from playing a file in the background. matherp or Geoff would indeed be able to tell you if that is normal, but this short delay at the end of playback could, in fact, be normal.

Your code seems to halt at the end of playback(not your doing), but then resumes a second or so later, which may be unwanted, but normal. We'll wait and see what the guru's say.
