Hi all.  Well thanks everybody for the responses concerning my
question about parameter blocks and trying to find out whether a file
is a folder or a file.  I just wrote some functions to access the
parameter blocks.

Now another question has come up.  We're intersted in writing a system
that is composed of many processes all talking to each other and
passing data back and forth.  Even under MultiFinder I haven't seen a
lot of this done so I conclude that it is an ineffecient and difficult
to program sort of thing to do.

Is multitasking difficult to do on the Mac?  Is it effecient?
Creating seperate processes would make the architecture of our system
nice and clean, but if it's going to load the machine needlessly then
we don't want it.

Can anyone provide pointers to technical notes or other references
concerning MultiFinde and MultiTasking (and XCMDS too I guess).

Thanks!
