General-purpose computing with VASYL

Here it is. I added some commentary to explain what's going on - I hope it's clear enough. Build and link as usual, run, then stop the display list and examine the very first two bytes of VASYL's memory - they will contain the preserved contents of ADR1.

Not sure if this helps with the SUBLEQ PC issue, but the demonstrated tricks may be handy for other things.
