Calling any program as a subprogram
Select the functions for program call: Press the
PGM CALL key
Press the PROGRAM soft key for the TNC to start
the dialog for defining the program to be called.
Use the screen keyboard to enter the path name
(GOTO key), or
press the SELECT PROGRAM soft key for the TNC
to display a selection window in which you can
select the program to be called. Confirm with the
END key
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 called program is not located in the same
directory as the program you are calling it from,
you must enter the complete path, e.g.
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
%. So please note that changes to Q parameters
in the called program can also influence the calling
program.
Danger of collision!
Coordinate transformations that you define in
the called program remain in effect for the calling
program too, unless you reset them.
