Hi,

Can anyone tell me how to reduce application size of a Turbovision
program compiled with djgpp. A medium sized TV application easily
becomes 1MB in size, and I need my executable to be much less in size.
Can I modify the TV libraries ? I dont need any internationalization.
If I dont need the mouse, how can I remove mouse handling.

The reason I need this is that whenever I reach a certain line of code,
my program crashes. I have identified the exact line in my code on
reaching which the program crashed. This line of code itself is not the
culprit (no illegal memory access) because when I reduce the
application size by deleting the lines before this line, the
application does not crash.

The crash dump is given below:

Any help will be appreciated!!
