{
There is two files, wich contains unit(s) and a demo program:
One to play big vocs (bigger than 64 KB) on SoudnBlatser, without
drivers (SBXMS).
Another to play same files in Protected Mode. (SBDPMI).
I hope that you can include those files in the next update of your SWAGS.
Greatings,
Gael of Kilobug.

A simple unit to play VOC files via DMA using XMS memory.
WARNING! This file can be compile only by Pascal 6.00 or higher in DOS
Real Mode. It don't work in any protected mode!
Remember: Pascal do NOT free XMS memory when halted program.
Please don't forget the "StopPlay" procedure.
