I'm another complete tyro trying to do something similar but for hex,
binary, and decimal arithmetic (guess who's hacking an assembler
together?) but although I have the grammar from the texts which makes
sense to my head, I haven't managed to make sense to a program yet.


Want to get together off-line to discuss ideas? I guess they're still
a bit primitive for this group (no offense, but I don't want to
clutter things up here with what appears to be basic stuff which *I*
just don't yet happen to understand)
