VMS Help DCE_SECURITY, Admin Intro, DCE$EXPORT, File Info  *Conan The Librarian (sorry for the slow response - running on an old VAX)

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

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