Scatter loading. Except for Aztec 'C' programs in default mode (why does
Aztec keep doing this: you can't write a nice, well-behaved, 'C' program
without changing a bunch of defaults. Such an ugly wart on such a nice
compiler.) programs on the Amiga can scatter-load. Potentially each seperate
module can be loaded at a different location.

There is a problem: screen and window memory needs to be contiguous... and
then of course there's that RAM: 30K ripcord. but program loading shouldn't
be a problem.

I never took CS 1001. Our introductory CS courses were CS1 and CS40. CS1
was in Fortrash with card decks.

Nope. No resource tracking. Ack, oop.
