When I try to compile one large DPMI program, I got a Compiler Error 49 (Data segment too large). But all Data I have for the data segment have only about 40kb. Is there any solution for this problem?

what are your compiler settings ? Do you use any directives such as $?- or $?+ etc. ?

Try to move some data into run-time allocated pointers.

The maximum data-size Pascal can handle must lie withing one segment, this is, 64 Kb (actually 65520 bytes due to some bytes of overhead).

If compiler is notifying you the excess, you surely has something that's going beyond 64 K, keep in mind that a single mistake in Var section (for example: a "0" added at an array declaration multiplies its size by 10). You always can allocate dynamic structures (using "New" procedure at run-time), which are defined at another segment, thus enabling you to go over the one-segment limit.
