The files and programs are stored in the program memory and are thus permanently stored
(passive file system).
Example: Main programs and subroutines, macro definitions.
Main programs and subroutines are stored in the main memory. A number of file types are
also stored here temporarily and these can be transferred to the working memory as
required (e.g., for initialization purposes on machining of a specific workpiece).
