The sample device driver I wrote for Chapter 11 of "The MS-DOS Papers"
will do what you want.  It recognizes a superset of the BASICA SOUND
statement as well as correcting some errors in the BASIC implementation.
Since this is a device driver,  one can open it and send characters
to it from any language.  The following C fragment

	fp=fopen("SOUND","w");
	fprints(fp,"%s","O3T100L8GFE-FGGGPFFF4");

plays "Mary Had a Little Lamb".  The complete source code for this driver
can be found at the end of the chapter.  If you don't feel like typing
it all in,  it is also available (from me) on a supplemental disk.  The
$10 fee I charge for each disk just covers reproduction,  materials,
and mailing costs.  All the code on this disk carries the following
notice:

	so long as this copyrite notice is retained and usage
	restrictions are observed.  This software may not be

This driver started out as a fairly simple example but grew into a
fairly sophisticated piece of code.

I hope this helps.
