Does anyone know why this program works "as-is" i.e. with no extra pre-compiler #include lines: /*---------------------------*/ int main() { getch(); } /*---------------------------*/ If getch() is declared in conio.h (I think it's in grx20.h as part of the GRX library, too), then how on earth can gcc under rhide compile the program, and run it, and return the code of the keypress, without some header file or other? J-P
