Using the keyword void within the brackets is the correct way to tell the compiler that the function takes NO arguments. if you don't believe it, whip up two programs, one with int main() and one with int main(void), and compare them with a file comparison tool. they will not be the same (i've checked - gcc-3.4.5). -jjh
