++During the execution of the scan program, the executed program can be called by the CALL instruction.
  A subroutine is to split a certain module in the main program for the main program to call, which is conducive to the modularization of the program. Such as other high-level language functions, but this function has no parameters and no return value.

++1. Instructions for calling subroutines
  After a new subroutine is created, the content of the program is not executed. It is executed only when the CALL(P) instruction is used to call the subroutine in the scan, event, and interrupt programs, and the call is executed once. Three new subroutines SUB0, SUB1, SUB2 are created as shown in the figure below. In the main program MAIN, the subprogram can be called by using the CALL(P) subprogram program name.

++**~      1.✎Note:**
 . When using the timer (OUT T), note that the output will not be reset when the subroutine is not called, and a specific subroutine register must be used.
 . It is not allowed to call recursively between subprograms, that is, call SUB1 in SUB0, and then call SUB0 in SUB1. This is not allowed.
 . The subroutine can be nested up to 32 levels. If the level exceeds 32 levels, a serious error will be reported and the Circuit program operation will be forcibly stopped.
 . Unlike the LX3V series mainframe, the subroutine in the LX5V series mainframe ends with the END instruction instead of SRET.
