David:

I hate to correct a genius but I get so few chances <g>. I got the original info from your website a few days ago (thanks!) Your're sample below wasn't quite right. Here is one that works.

* this program plays a sound for 10 seconds
#define SND_SYNC 0x00
#define SND_ASYNC 0x01
#define SND_NODEFAULT 0x02
#define SND_LOOP 0x08
#define SND_NOSTOP 0x10

declare integer sndPlaySound in winmm.dll string cSoundName, integer uFlags
=sndPlaySound( "c:\windows\media\ctmelody.wav", SND_ASYNC + SND_LOOP )
=INKEY(10)
* you could put some usefull processing in here instead!
=sndPlaySound( .NULL. , SND_NODEFAULT)
