This statement controls the source which BASIC uses for INPUT and KEYS entries. The IN# statement allows more than one port to be selected at any given time.
However, if ports 2,3,4 or 5 are selected, the port with the highest number will be given priority and all input will come from that device.
IN# int -exp
will select that device as the ONLY
input device.
IN# int-exp ON
will select that device and leave the
status of all other input devices
unchanged.
IN# int-exp OFF
will de-select that device and leave the
status of all other input devices
unchanged.
Performing a WARM or COLD RESET will reselect device 0 (the microbee keyboard) as the input device.
