I have a few questions related to problems I am having using
turbo C in a turbo IBM clone. It is very important I figure this
stuff out soon.

1> In turbo C, how do I know how long the program will be so I can
make it a Terminate and Stay Resident (TSR)

2> What should a TSR do to remove itself completely from memory
when it is no longer needed? (doscall or whatever)

3> How can a tsr program tell if its already loaded once before to
avoid duplication

4> How can I get 25 interrupts per second without screwing up
the channel zero of the timer and thus confusing dos and messing
up the clock.

Thanks so much for any help.
