Very basic sound programming question

[Jim <jim@magrathea.plus.com>]

I'd like to have a subroutine in BASIC that emits a fairly low beep,
followed by a fairly high-pitched beep. Both beeps would be of very short
duration, say less than 0.5seconds.

Any pointers as to how I could achieve this? It would be with whatever the
standard BASIC is on DOS3.3, for a fairly plain vanilla //e

Many thanks for any tips.

Jim
