Question:
I have a C program, compiled with Microsoft C Version 5.00, which
consists of several modules linked together as overlays. I am not able
to trace into code in the overlays. I compiled in the default memory
model. What is wrong?
Response:
The modules must be compiled in medium or large memory model to be
overlaid. In the default model (small), or in the compact model, there
is only one code segment, which cannot be overlaid. The main module is
always resident and cannot be overlaid. You must use the compile
option /AH, /AL, or /AM.
