I haven't had time to follow the decoding threads so perhaps I'm
missing something.
_I_ didn't limit me to only base64 characters. Because as I wanted my
program to run on a 8086 and as there is no popa, I had to use pop %bx
and friends. Otherwise mission impossible.
If you can show us a way to get an offset without pop %bx, %bp, %si,
or %di into one(all?) of these registers (8086 code, .COM text file,
base64), I'd be grateful. Currently we seem to think it's impossible.
As to why the self-commited limit, no reason. You just decide on the
rules and hack away. Obviously Terje and Kerr(?) decided they wanted
those rules. I wanted my 8086 rule. You can decide to follow other
rules. It was just a fun and challenging exercise.

The mail things of old were easy to break as some parts only supported
this and other parts only supported that. Now (probably) the odd
computers and routers and whatever have been replaced and the new ones
are more compatible.
So you decide the rules and tell and show us (if you want).
