There are at least three versions that I'm aware of tone generator functions. The first one was included in the SV-ROM but it's a little unstable. The second is TONEZ, in Doug Wilder's BLDROM. The third is TONEXY, written by Nelson F. Crowle if I'm not wrong. All use the same inputs for frequency and duration in X,Y registers - or the other way round, but the same concept nonetheless.

Just for fun I used TONEXY on the 41Z module to provide an audible signal on the complex results, using the real part for frequency and the imaginary for duration.
