Real mode pointers are all 16 or 20 bits, which already limits you to a maximum of 1 meg of memory. Even if you could use a larger pointer size, there is no virtual memory management in real mode. I guess you could rewrite your compiler to trap memory references to paged memory, and then, if necessary, reload it from disk. If you're really running applications that need a large amount of memory, you should consider switching to a protected mode compiler.
