Global and static data go into a combined segment called DGROUP.  The 
machine hardware limits a segment to 64K.

If you add the keyword 'far' to a global or static data items, the 
compiler will flag it to be placed into a different segment and not in 
DGROUP.  Try locating a few of the largest global data items and 
adding that keyword to them.

For example:

  char far big_array[2048];

The language standards committee dictated that compiler-specific 
keywords begin with an underscore.  It has been a while since I did 
this with BC++ 5.02 and I don't remember how strictly this is 
enforced.  If it gives trouble with 'far', then use '_far'.

Please let us know how this works for you.
