It bothers me that you're recommending that someone disassemble my code
and use it verbatim.  Whether or not this is legal, I have no idea, but
please note that play.prg is COPYRIGHTED, although it's freeware.  It's
NOT public domain.  This is the sort of thing that makes people not
release their software as shareware at all, especially considering that
only a handful of people every attach the programmer's name to the "gift"
in references like the above.

For the record, I've gotten many requests for my sample playing source
code, and I regret that I can't give it out because it's for a
commercial product.  In the past I have given detailed explanations of
how to play digitized sound on the ST, posted here.  I don't have time
to do it again at the moment, unfortunately.

Instead of disassembling play.prg, please look for resound.arc on
atari.archive.  If it's not already there, I'll put it there.  It's by
David Snow and implements the same techniques my routines do.  Source
is included in the arc file.

I don't mean to flame you, Warwick.  On the contrary, I'm glad you
post here -- your articles are quite helpful.  But consider how you'd
feel if I disassembled STrabble and used your dictionary without
your permission.
