 I am using signal() in a MSC4.0 program, to catch CTRL-C - everything
works fine. However, parts of the program consist of lengthy math
routines, and the response to the CTRL-C can be quite slow (5-10
seconds). I believe that this occurs because DOS only checks for
CTRL-C while making BIOS calls. Is this true? If so, what is a good
way around it. Make "dummy" BIOS calls in the math routines? Any
suggestions would be appreciated.
