	I have ran into this problem before to.  My brother regularly 
corresponds with someone that helped with the 3.0 MCW developement.  so 
here is the reason.  The MWC compiler uses signed short offsets from a 
stack value for local variables.  this means that you have 15 bits or
32K to use as an offset, question answered.  This is not true of global
variables.  All global variables are long offset from a base address so
the problem does not exist and structures and arrays can be as big as
wanted.

	Hope this helped.  I was taught to not use global variables much but 
it seems that they have their place.
