[Coco] Programs larger than 32K?

 Thanks for the tip.  The context for this is that the program was dumped out my my text-adventure tool.  Right now it's about 29K, but I'd like to be able to write games that can use the entire 64K. I think what I'm going to do is use the Pierre Sarrazin's no_basic demo and have it load the game into memory at at known location, then JSR into it.

   Did you try to do a PCLEAR0? This is not a BASIC feature but can be
  done by slightly modifying the BASIC interpreter. I can't remember the
  exact procedure procedure but do a search. Google is your friend. If by
  putting your CoCo in All RAM mode is what you do to get it to work then
  most likely you are doing a PCLEAR0 method. This will give you about an
  additional 2K of program RAM. Other then that.... Nope.

    Is there a way to load a program BASIC that is more than 32K?  (I
    have a  program that is too large to fit into the  CoCo 2 when it's
    not in all-RAM mode)
    If put the machine in all-RAM mode from BASIC the machine crashes
    (which is kind of expected). But,  I can't have the program put the
    machine in all RAM mode, because I can't get it loaded in the first
    place (the CMOC nobasic example).
    Do people have a main segment that is less than 32k, which puts the
    CoCo in all-RAM mode, then load the remaining data from separate
    files?
