Once more, someone has been been hit by the 64KB Wall of 16-Bit
Messy-DOS compilers.  To fix that, use a different, i.e.  a 32-Bit
flat-memory model compiler (judging from the other platforms in use, the
DOS port of gcc, called DJGPP, is what you're looking for).  All other
possibilities would break the code for other platforms, or at least
bring that danger with them.

This is probably a problem with your memory model, that will currently allow 
only 64K of code. Use large model, which should be able to handle >64K code.

Or simply change memory model in your compiler options (providing
it has such an option) - the 64kB limit is in Tiny/Small/Compact
only, use Medium or Large. Note: for Medium must remember pointers
to code and data are not of same size, avoid converting pointer to
function to void pointer and back, it causes incorrect result.
Large causes all pointer to be 4-byte, as it is on other machines.
[it is assuming you program in C based on group you post to]

Moving to GCC/DJGPP is necessary when you hit 640kB...
