I currently run my BBS using a rexx script under OS/2.  That's how I've
done it for the last 2 years or whatever, but now I want to change.  I want
the mainline to be a C program, and I want to call the utilities (bt.exe
etc) from my C program, using system().

Although not a problem under OS/2, I would also like to have the ability to
run from DOS if required.  I know most people go to great lengths to not
call system() under DOS, in order to save memory, and use functions like
spawn etc.

I'd like to know whether the fact that my program is going to be quite
small (consisting mainly of cd's and system's) is going to mean that I
don't have any problem worth bothering about under DOS.

Oh, I'm also intending that this same program be used under Linux, so that
I can boot my system under Linux or OS/2, and it does exactly the same
thing as far as the BBS callers can see.

BFN.  Paul.
