A new horizon is opening up for Clipper. The power of sound from within
 our applications is now possible.  Advise your users with sounds for
 errors, warnings, etc.  Let your imagination run wild.  Lets go to
 multimedia naturally with Clipper.

    In version 2.00 the ability for sound in Clipper was given.  In that
 version there was only support for Sound Blaster and Sound Blaster Pro.
 Since then I received lots of petitions to extend this subsystem to the
 Parallel DAC and the Speaker.

    Now we break that wall and give you the possibility to generate sound by
 the parallel DAC and by the speaker.  Not everybody has a Sound Blaster, but
 a speaker is on every machine.

    The maximum frequency depends on the speed of the processor and the
 drivers in memory.

    The most difficult part of sound generation have two aspects.  The first
 is the sparse information about sound formats. The second is the VMM
 system stopping while the sound functions execute.  Compatabilty has been
 achieved with the Sound Blaster, but not yet during DAC and speaker functions
 where the dear VMM pauses in silence.
