If you use the "CNC user memory extended" software option, the subprogram can be stored on
the system CF card in a program memory configured for EES.
Without these two software option, the subprogram must always be stored in the NCK work
memory (in a separate "XYZ" directory or in the "Subprograms" directory). If you still want to call
a subprogram located on another drive, you can use G code command "EXTCALL".
Program header
Please note that when a subprogram is called, the settings in the program header of the
subprogram are evaluated. These settings also remain active even after the subprogram has
been exited.
If you wish to activate the settings from the program header for the main program again, you
can make the settings again in the main program after calling the subprogram.
