Calling a program with SEL PGM and CALL SELECTED PGM
Use the function SEL PGM to select any program as a subprogram
and call it at another position in the program. The control runs
the called program from the position where it was called in the
program with CALL SELECTED PGM.
The SEL PGM function is also permitted with string parameters, so
that you can dynamically control program calls.
To select the program, proceed as follows:
To select the functions for program call, press
the PGM CALL key
Press the SELECT PROGRAM soft key
The control starts the dialog for defining the
program to be called.
Press the SELECT FILE soft key
The control shows a selection window that
allows you to select the program to be called.
Press the ENT key
To call the selected program, proceed as follows:
To select the functions for program call, press
the PGM CALL key
Press the CALL SELECTED PROGRAM soft key
With CALL SELECTED PGM, the control calls the
last program selected.
If an NC program that was called using CALL SELECTED
PGM is missing, then the control interrupts the
execution or simulation with an error message. In order
to avoid undesired interruptions during program run, all
paths to the program beginning can be checked using
the FN 18 function (ID10 NR110 and NR111)

system data", page 392
