Hi,

The easiest way to slow down Xst Basic is to include some kind of millisecond time 
delay in the main loop.
Eg:

 T=GetTime(3)
 EXTRATIMEDELAY=0
 Do
  If GetTime(3)>T+EXTRATIMEDELAY Or GetTime(3)<T Then PopLoop
 Loop


EXTRATIMEDELAY=0 works in XST 1 and EXTRATIMEDELAY=10 works in Xst 2 (on my computer).
Experiment with different values.

Hope this helps...
