When the GUD definition file is loaded into the NC ("Load" soft key), it becomes active.
See "Automatic activation ..." If the content of a particular GUD definition file is re-
activated, the old GUD data block in the active file system is deleted and the new
parameters reset. If this process is undertaken via the dialogue HMI services => Manage
data => Define and activate user data (GUD), then the variable contents are saved by INI
file and re-established at the end of the process.
When the file _N_COMPLETE_GUD is archived from the working memory, only the data
contained in the file are saved. The created definition files for the global user variables
must be archived separately.
The variable assignments to global user data are also saved in _N_INITIAL_INI; the
names must be identical with the names in the definition files.
