* SUBROUTINE CALL
Call the subroutine program which begins at the designated step in a
file. Subroutine call must be ended by "M42" (return from subroutine).
When the program meets the command "M42", it returns to the main
program from the subroutine by "M40". The step to return is the next
step of "M40".
Successive subroutine calls are possible for 3 times, if over then the
motion stops and error message ("SUB-CALL OVER 3 ") is displayed.

M42
* RETURN FROM SUBROUTINE
It returns to the main program from the subroutine by "M40". The step
to return is the next step of "M40". If the program meets the command
"M42" without declaration of "M40", then the motion stops and error
message ("SUB-RETURN ERROR") is displayed.
NO NO
M50
* JUMP
Jump to the designated step in a file and continues to execute the
program. 0 95
M56
* JUMP BY BCD
Jump to the designated step in a file if the designated BCD value is
equal to the external BCD input, or jump to the next step if the
designated BCD value is not equal to the external BCD input.
External BCD input is determined by input-13,12,11,10.
The BCD input is useful when you want to branch the program by
external inputs (PLC, switches, etc.).
