How can I establish what RAM I need...and therefore which PIC.

Hi Hank,
Instead of using a bunch of spaces have you tried "lining up" you columns by sending the ASCII code for TAB, I think it's 9, that might save a couple of bytes here and there.

Another option worth looking into is to use the REP modifier, these two lines:

DEBUG "Ten spaces to follow:          ", 13, 10 
DEBUG "Ten spaces to follow:", REP " "\10, 13, 10

Prints the same thing on the screen but the second takes up 6 bytes less space. Obviosuly there's a break-even point where the extra codespace needed by REP eats up more than simply spelling out the repeated characters but you get the idea.

Good luck!
/Henrik.
