VMS Help DEFINE, Qualifiers, /JOB  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Places the logical name in the jobwide logical name table. All
    processes in the same job tree as the process that created the
    logical name can access the logical name. The /JOB qualifier is
    synonymous with the /TABLE=LNM$JOB qualifier.

    If you enter more than one of the qualifiers /PROCESS, /JOB,
    /GROUP, /SYSTEM, or /TABLE, only the last one entered is
    accepted.
