Subroutines (subprograms):

  • Are usually a series of commands that are repeated several times in a program
  • Are written in a separate program, instead of repeating the commands many times in the main program
  • Are called in the main program with an M97 or M98 and a P code.
  • Can include an L for repeat count. The subroutine call repeats L times before the main program continues with the next block

When you useM97:

  • The P code (nnnnn) is the same as the program location (Onnnnn) of the subroutine.
  • The subprogram must be within the main program

When you use M98:

  • The P code (nnnnn) is the same as the program number (Onnnnn) of the subroutine.
  • The subprogram must reside in the control memory or hard drive (optional).
