Do not save files onto your master system disc; indeed you should NEVER even risk writing to it by closing its write-protect holes. If you are using the CP/M 2.2 version of Dr. LOGO (on Side 4 of your master package), you cannot change discs mid-session, so it is vital that your CP/M 2.2 Dr. LOGO working disc has plenty of free space for programs. * setd (set drive) Makes the specified drive the default drive. ?defauLtd A: ? d i r [BOXES CIRCLE STARS] ?setd "b: ?defauLtd B: ? d i r [TRIANGLE HOUSE] I{eyboard and Joystick: buttonp (button pressed) Outputs T RUE if the button on the specified joystick is down; numbers 0 or 1 identify the two possible joysticks. ?to fire >LabeL "Loop >if (buttonp 0) [pr [fire 0!]] >if (buttonp 1) [pr [fire 1!]] >90 "Loop >end The position of the joystick is tested by padd Le.
