Well, sometimes there's just no other way, really, as was in the case of
getting that pointer to the font table. Sometimes I feel as guilty as using a
global variable, though.

They should design better hardware. ;> Actually, it's hard enough to keep up
with the changes. I guess some things have to be put up with.

Good point (pun not intended) Sometimes I feel like my brain is like that.
But then the compiler should have code that would engage when a page is freed
(doesn't it trigger some kind of IRQ or call?) and then it would update the
pointers...  or some crazy thing I have no idea what the heck I'm talking
about!

GOTO! Yuk  don't say that *word* (it's even taboo in BASIC these
days!) It can't be that* bad? Maybe realloc can be compared to using global
variables for 5% of your code, but not as bad coding as gotos! ;)
