Is it possible to run two tasks at once on a Mac?
Specifically, can a background task behave in the 
same way that TSR's can on a DOS pc?

This is my application: I write and adapt programs
for severely handicapped students.  Adapting
3rd party programs involves 2 things:
   1.  slow the program down so that a handicapped
       user, using an adaptive switch/es, is
       able to respond to the program
   2.  substitute switch input for keyboard or mouse
       input.  (on a pc, I do this by popping up
       a tsr, which responds to an adaptive switch,
       and places the selected keystroke in the
       standard DOS keyboard buffer).

I am, at this point, entirely ignorant about Macintosh
programming.  I've been asked to evaluate Macs for
handicapped use.  I'll appreciate any comments.
Thanks.
