File and Program Management
2.1 Program memory
Creating a workpiece directory without a path name
If the path name is missing, files with the _SPF extension are stored in directory /
_N_SPF_DIR, files with the _INI extension are stored in the RAM and all other files are stored
in directory/_N_MPF_DIR.
Example:
Program code
%_N_SHAFT_SPF
...
M17
File _N_WELLE_SPF is stored in directory /_N_SPF_DIR.
Select workpiece for machining
A workpiece directory can be selected for execution in a channel. If a main program with the
same name or only a single main program (_MPF) is stored in this directory, this is
automatically selected for execution.

Search paths for subprogram call
If the search path is not specified explicitly in the part program when a subprogram (or
initialization file) is called, the calling program searches in a fixed search path.
Subprogram call with absolute path
Example
Program code
...
CALL"/_N_CST_DIR/_N_CYCLE1_SPF"
...
Subprogram call without absolute path
Programs are usually called without specifying a path.
Example
Program code
...
CYCLE1
