Load
If a definition file is loaded, a prompt is displayed
asking whether to activate the file or retain the data.
If you do not activate, the file is not loaded.
If the cursor is positioned on a loaded definition file,
the softkey labeling changes from "Load" to
"Activate" to activate the definitions. If you select
"Activate", another prompt is displayed asking
whether you want to retain the data.
Data is only saved for variable definition files, not for
macros.
Additional notes (MMC 103)
If there is not enough memory capacity for activating
the definition file, once the memory size has been
changed, the file must be transferred from the NC to
the MMC and back into the NC again to activate it.
