2.3.7.5 Timed Response Any Button (#Q)

The Timed Response Any Button command pauses Cogsys execution until any of the gameport buttons are pressed or the specified timelimit expires. Each button is given a letter:

`A'

Joystick 1, Button 1

`B'

Joystick 1, Button 2

`C'

Joystick 2, Button 1

`D'

Joystick 2, Button 2

The corresponding letter is written to output with response time. If no key pressed within the time limit, '&' is written to output.

Warning: If more than one button is pressed, the binary code representing the button combination is written as key pressed. Note that this may confuse programs expecting pure ASCII text.
