Calling any program as a subprogram
Danger of collision!
Coordinate transformations that you define in the
called program also remain in effect for the calling
program too, unless you reset them.
If the program you want to call is located in the same
directory as the program you are calling it from, then
you only need to enter the program name.
If the program called is not located in the same
directory as the program you are calling it from, you
must enter the complete path, for example TNC:
\ZW35\SCHRUPP\PGM1.H
If you want to call a DIN/ISO program, enter the file
type .I after the program name.
You can also call a program with Cycle G39.
As a rule, Q parameters are effective globally with a
program call with %. So please note that changes to
Q parameters in the called program also influence
the calling program.
Call a program with Calling a program
The % function calls any program as a subprogram. The control runs
the called program from the position where it was called in the
program.
To select the functions for program call, press the
PGM CALL key
Press the CALL PROGRAM soft key: The TNC
starts the dialog for defining the program to be
called. Enter the path name with the keyboard
or

a selection window in which you can select the
program to be called; confirm with theENT key
