Example of using Sound Deluxe System in POLL mode from an external Pascal
program. _very_ _very_ _very_ simple example - a stupid screen split in
vga's mode-x, but it's anyway here only as a demonstration of using sync
tracking from a Pascal program!

The original mode-x routines by Kaos/Black Magic, because I'm veeeery laaaaazy
and I don't want to start code such things in pascal right now!

To see how the sync is done, set 'TimingBar' constant to 1 (into the kernel's
file DEBUG.INC) and recompile the whole shit again. Funny things will happen...
