Well, in DJGPP I remember there being a clrscr (sp?) function in conio.h, but it isn''t there in VC++ (that I''ve found). The next closest thing would be system("cls"). system should be declared in process.h or stdlib.h.

Well, if cls is in one of those header, what would the syntax look like? just a plane old:
cls; // ?
Thanks for the help!

cls; // ?

You could make your own cls function.
-Forcaswriteln("Does this actually work?");

Are you suggesting that all of humanity cannot provide an answer to this question? If no one can answer it, why are you asking?

Going to the MDSN and searching for "clear screen console" provided this bit of code :
