First, read the doc on Ptermres(). It tells you how to terminate a program
of yours aqnd stay resident. If you want something like a hot-key, you will
have to link your program into one or the other vector; in a screen saver,
for instance, you might intercept the mouse movement vector so that
a routine in your programs is being called whenever you move the mouse.
These are the basics how it works - details depend on the kind of TSR
you want to write.
