I have a program that is over 1M, and I'm wondering how it runs in DOS. Everyone, please give me some pointers.

Are there any special aspects about pointers in the program? Are all pointers restricted below FFFF:FFFF? If the address to be addressed exceeds FFFF:FFFF, how is it handled? Please give some guidance.

Google search for DMPI. Now Watcom C++ and DJGPP already support protected mode programming under DOS.
