I think I remember, but ive just started getting back into atari - and havent used atari basic for well over 30 years (other basics and languages i have).
It was a very basic and simple sound program, and it needed to be short and easy to type in the shops atari, and then leave pronto! Anyway, this is what i remember typing in.
Nothing special, but it didnt need to be! ;o)
Cheers.
