System information

SECTION FIVE - MISCELLANEOUS FUNCTIONS (M CODES)
When the main program calls a subprogram, it is regarded as a one loop nest. A two loop nesting
can be executed as shown below.
When used with an L___ command, an M98 command can call a subprogram repeatedly. An
L___ command can specify up to 999 repetitions of a subprogram.
Nesting with up to 50 loops is allowed.
M2 can be used instead of M99. If a subprogram ends without an M2 or M99 it will return to the
calling program as if an M2 or M99 was encountered.
Preparation of subprogram
A subprogram is the same as any other program.
Specifying M99 at the end of a subprogram is optional. If the program was called by an M98, an
M02, M30 or M99 will return. Subprograms are entered into memory in the same fashion as
normal programs.
