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
...
The directories are searched for the called program in the following sequence:
No.
