I have a question which I do not know if this related to CWSDPMI. I develop my programs in a Windows XP DOS box and they work fine there. When I then try them in real mode DOS they crash due to uninitialized pointers. So I have to work through the program again and fix that. But some of these problems I may not find and my users observe crashes.

Does Windows DPMI set the allocated memory to zero for you while CWSDPMI does not? Then a "char* mystring;" is set to NULL by Windows.

Georg
