M98 Subprogram Call
The M98 is a function to call a subprogram from the program currently running.
Specify a subprogram to call by a number next to the P argument.
The called subprogram is executed from the first block.
When M99 is executed in the subprogram, the execution control returns to the main program from
which the subprogram was called.
If the specified subprogram is not found, an alarm is output and the program stops running.
When you specify P1000 as shown in the following sample, subprogram 1000 is called.
Also when you specify the number 10 after the L argument as shown in the following, the subprogram
can be called 10 times.
Subprograms must be called within the depth of 8. The depth is counted from 1.
If the depth exceeds 8, subprograms are not invoked but the next block is executed.
Refer to the programming example of G50.1, G51.1 Mirroring on page 2-55.
