Also the documentation refers to relocating large blocks with the -F
switch.  This allows individual structures of > 32K to be relocated
to their own segment, and there is also a way to change the threshold
allocation to be other then 32K.  I saw it in the Programmers
Reference Manual, I think.  The IDE also aloows this to be adjusted in
the Compiler Options Section.
