I guess it does. And that sure is easy. If that is indeed the best way
to do it, do it I shall! 

I've not used this system() command until a couple days ago. Now,
because I'm trying to negate the need for external batch files with
this compiler I've discussed elsewhere, I am relying on system() calls
heavily, and I am a bit paranoid of it and of what penalties I may
have to pay for suspending my program while I let other programs do a
bunch of stuff. If you know of any particular dangers or "no-nos"
regarding system() usage with DJGPP, please post. 

Thanks much, everybody!
