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

       /TABLE=name

    Specifies the table from which the logical name is to be deleted.
    Defaults to LNM$PROCESS. The table can be the process, group,
    job, or system table, one of the directory tables, or the name
    of a user-created table. (The process, job, group, and system
    logical name tables should be referred to by the logical names
    LNM$PROCESS, LNM$JOB, LNM$GROUP, and LNM$SYSTEM, respectively.)

    The /TABLE qualifier also can be used to delete a logical name
    table. To delete a process-private table, enter the following
    command:

    $ DEASSIGN/TABLE=LNM$PROCESS_DIRECTORY table-name

    To delete a shareable table, enter the following command:

    $ DEASSIGN/TABLE=LNM$SYSTEM_DIRECTORY table-name

    To delete a shareable logical name table, you must have delete
    (D) access to the table or write (W) access to the directory
    table in which the name of the shareable table is cataloged.

    If you do not explicitly specify the /TABLE qualifier, the
    default is the /TABLE=LNM$PROCESS qualifier.
