	I'm leaving my current job to programme Macs for a living (Yay!). One
of my first jobs will be porting a programme from IBM (spit!) PCs (blechh!)
to the Mac. However there is a fly in the ointment. Without giving too much
away about what I'll be doing I'll try and describe what's going on. In the
PC (ugh!) version of the program a terminate-and-stay-resident block of code
is loaded and then the main application runs and uses services provided by
the first program by executing software interupts.
	Is it possible to do something similar on a Mac without too much 
trouble? One solution might be to use the interprocess communications
facilities provided by System 7 but the software is intended for academic
use and there are a lot of people with one meg macs who will not be happy
with this as a solution. Can a CDEV provide a similar service in a one
meg machine? (I'm really fishing here!) Any help as usual is gratefully
received.
