I hope this is the right group for these questions, and they haven't
been asked too many times before.  Here goes:

1.  I want to intercept the Ctrl-C behaviour in a Zortech C++ program. 
I used int_intercept(); and it seems to work fine (all I do in my
intercept function is set a flag) and I keep control.  But...  it still
echoes ^C on screen.  How do I stop it from doing that? I gather that
it's DOS rather than the BIOS that detects ctrl-Cs.  Does that mean I
have to do all my IO using the BIOS if I don't want DOS interfering, or
can I clear the 'break' condition before I call DOS so it never sees it?
Does any of this make sense?

2. Has anyone got a good reference for using overlays on the PC?
Basically I've got a v. large program (again Zortech C++) and I
want to split it into manageable chunks, some of which need information
passed between them.

Thanks a bundle.
