Because it's easy enough to simply write RST 10H!

Yep.

What do you mean by description offset??

The most compact way to find a variable, e.g. REAL variable "ABC"
would be this:
LD HL,sokstr
LD DE,(PROGRAM_ADDR)
ADD HL,DE
RST 20h
RST 10h
sokstr:
.db $00,$03,"ABC"

That's strange. My DASM gives me RST nnH. That works with TASM. :)

Nop. That would be illegal copying! But if you promise to keep your
lips sealed I can send you a copy of mine. ;-)
