    I'm guessing that you are thinking of something else from <conio.h>, e.g., getch().

    Actually Pelles C does have a "private" (i.e. non-standard) header for conio that does include _clrscr() as a function.

    So, you are saying that Pelles C needs _clrscr()?

    Yes. I know it's "not like everything else"... but it is a non-standards based function to begin with.

    No, Pelles C does not need _clrscr(), otherwise your programs have been lacking a call to _clrscr(). Pelles C provides _clrscr() as part of the library it comes with.

    Oooookaaaaayyy.... I thought you meant the underscore as in .... _clrscr() as opposed to clrscr() from Turbo C.
