optional stop

A switch on the CNC controller that works if there is an M01 code in the program. When the control reads an M01 and the optional stop switch is on, the control will halt the execution of the program. If the switch is off the program ignores the M01. Compare to M00, (program stop), M02 (end of program no rewind), and M30 (end of program with rewind)
