Qualifiers

/ALL
   Deletes all logical names in the same or an outer (less
   privileged) access mode. If no logical name table is specified,
   the default is the process table, LNM$PROCESS. If you specify the
   /ALL qualifier, you cannot enter a logical-name parameter.


/CLUSTER_SYSTEM
   You must be signed in to the SYSTEM account or have SYSNAM
   (system logical name) or SYSPRV (system) privilege to deassign
   a clusterwide logical name.

   Deassigns a logical name from the LNM$SYSCLUSTER table.


/EXECUTIVE_MODE
   Requires SYSNAM (system logical name) privilege to deassign
   executive-mode logical names.

   Deletes only entries that were created in the specified mode
   or an outer (less privileged) mode. If you do not have SYSNAM
   privilege for executive mode, a supervisor-mode operation is
   assumed.


/GROUP
   Requires GRPNAM (group logical name) or SYSPRV privilege to
   delete entries from the group logical name table.

   Indicates that the specified logical name is in the group
   logical name table. The /GROUP qualifier is synonymous with the
   /TABLE=LNM$GROUP qualifier.


/JOB
   Indicates that the specified logical name is in the jobwide
   logical name table. The /JOB qualifier is synonymous with the
   /TABLE=LNM$JOB qualifier. If you do not explicitly specify a
   logical name table, the default is the /PROCESS qualifier.

   You should not deassign jobwide logical name entries that were
   made by the system at login time, for example, SYS$LOGIN,
   SYS$LOGIN_DEVICE, and SYS$SCRATCH. However, if you assign new
   equivalence names for these logical names (that is, create new
   logical names in outer access modes), you can deassign the names
   you explicitly created.


/LOG
      /LOG (default)
      /NOLOG

   /NOLOG overrides the default /LOG to suppress output of a fatal
   error that would be returned if the specified logical name were
   not found. When you specify /NOLOG, $STATUS is set to Success
   instead of to Fatal and no error message is output.


/PROCESS
      /PROCESS (default)

   Indicates that the specified logical name is in the process
   logical name table. The /PROCESS qualifier is synonymous with
   the /TABLE=LNM$PROCESS qualifier.

   You cannot deassign logical name table entries that were made by
   the command interpreter, for example, SYS$INPUT, SYS$OUTPUT, and
   SYS$ERROR. However, if you assign new equivalence names for these
   logical names (that is, create new logical names in outer access
   modes), you can deassign the names you explicitly created.


/SUPERVISOR_MODE
      /SUPERVISOR_MODE (default)

   Deletes entries in the specified logical name table that were
   created in supervisor mode. If you specify the /SUPERVISOR_MODE
   qualifier, the DEASSIGN command also deassigns user-mode entries
   with the same name.


/SYSTEM
   Indicates that the specified logical name is in the system
   logical name table. The /SYSTEM qualifier is synonymous with
   the /TABLE=LNM$SYSTEM qualifier.


/TABLE
      /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.


/USER_MODE
   Deletes entries in the process logical name table that were
   created in user mode. If you specify the /USER_MODE qualifier,
   the DEASSIGN command can deassign only user-mode entries. Also,
   user-mode logical names are automatically deleted when invoking
   and exiting a command procedure.
