I am planning to write a TSR program in the following way. I wonder if anybody
will comment on its feasibility:
	(1) Interrupt a running program;
	(2) Save all RAM content into hard disk;
	(3) Run the TSR program;
	(4) Upon finishing, load the original RAM content into the memory.
	(5) Return the control to the running program.

It sounds like a simplest kind of multi-tasking swap. I wonder if it is as
simple as I thought. Or there are some pitfalls here--I am not sure if there
will be any problem at step No.5.
	Hope to hear from you guys.

	By the way, I forgot to mention that I'm going to write it in Turbo
Pascal.
