Example:
The workpiece directory
/WCS.DIR/SHAFT.WPD
contains files
SHAFT.SPF and SHAFT.MPF.
When you select workpiece directory SHAFT.WPD you implicitly
select program SHAFT.MPF.
If the call path is not explicitly specified in the part program when a
subroutine (or an initialization file) is called, the called program is
located according to the predefined search strategy.
Case 1:
When a subprogram is called by
name with specification of the file type ("identifier" or "extension"),
e.g. SHAFT.MPF,
the system searches through directories in the following order:
1. Current directory / name.typ
2. /SPF.DIR / name.typ
3. /CUS.DIR / name.typ
4. /CMA.DIR / name.typ
5. /CST.DIR / name.typ
Case 2:
When a subprogram is called by
name without specifying the file type ("identifier" or "extension"),
e.g. SHAFT1,
the system searches through directories in the following order:
1. Current directory / name
2. Current directory / name.SPF
3. Current directory / name.MPF
4. /SPF.DIR / name.SPF
5. /CUS.DIR / name.SPF
6. /CMA.DIR / name.SPF
7. /CST.DIR / name.SPF
