The DCE DCE IMPORT utility is shipped as an OpenVMS executable image
 named DCE$IMPORT.EXE. The image resides in the SYS$SYSTEM directory.

 The DCE IMPORT exclude file is named by default DCE$IMPORT_EXCLUDE.DAT and
 also resides in SYS$SYSTEM. You can change the name or location, or
 both, of this file by defining the logical name DCE$IMPORT_EXCLUDE to
 point to the new filename and location.
