The program you are calling must be stored on the hard
disk of your TNC.
You need only enter the program name if the program you
want to call is located in the same directory as the program
you are calling it from.
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 12 PGM CALL.
As a rule, Q parameters are effective globally with a PGM
CALL
. So please note that changes to Q parameters in the
called program can also influence the calling program.
Coordinate transformations that you define in the called
program remain in effect for the calling program too,
unless you reset them. The setting of machine parameter
MP7300 has no influence on this.
