Hello. Can anyone enlighten me as to what is going on here? It runs OK, but
when I press F11 or F12 the program pauses. It can be restarted by pressing
another key. How do I get rid of this behaviour because I want to use F11
and F12 for something else?

I am running in a DOS box under Windows 98. The same behaviour has been seen
on another program running under Datalight DOS. More than likely the same
thing happens under MSDOS 6.22 but I have not tested this.


#include <stdio.h>
#include <conio.h>

int main( void )
{
	bool quit = false;
	int key;

	while( ! quit ) {

		putch( '*' );

		if( kbhit() ) {

			key = getch();

			if( key ) {
				quit = ( key == 27 );		// escape
key
			}
			else {
				key = getch();
			}

		}

	}

	return 0;
}
