According to the docs: "msvcrt.getch() - Read a keypress and return the resulting character....This call will block if a keypress is not already available, but will not wait for Enter to be pressed. If the pressed key was a special function key, this will return '\000' or '\xe0'; the next call will return the keycode. The Control-C keypress cannot be read with this function."
IOW - getch always returns 1 character. You are testing for a 0 length string. Will never happen. What keystroke do you want to break the loop? -- Bob Gailer 919-636-4239 Chapel Hill NC
