50/50   .. global/local  :)

With the 6809 and a modular component program, there is an art of 
separating local/global variables and DP/extended addresss variables, 
that's for sure!  Projector-3 combines all 4 in away that 1) lets temporary 
components/modules use some of the DP space for speed, 2) doesn't hog the 
DP space with infrequent or temporary variables, 3) lets each component 
have a huge local extended variable section, 4) lets all parts of the 
system, all components, know everything it *needs* to know by sharing a 
global variable section, which I placed in the DP area.

P.S.
I still say 100% assembly for the CoCo can't be matched with any compiler 
there is, with optomizer or not.  I know too much.  :)
