/LOGICAL=(NAME=logical-name[,TABLE=table][,MODE=mode])

 	Specifies a logical name to be associated with the actual name of
 	the created device.

 	You can specify one of the following options for the TABLE
 	keyword:

 	GROUP	Places the logical name in the group logical name
 		table. You must have GRPNAM or SYSPRV privilege to
 		place the logical name in the group logical name table.

 	JOB	Places the logical name in the jobwide logical name
 		table.

 	PROCESS	Places the logical name in the process logical name
 		table. This is the default.

 	SYSTEM	Places the logical name in the system logical name
 		table. You must have SYSNAM or SYSPRV privilege to
 		place a name in the system logical name table.

 	You can also specify the name of a specific table. For example,
 	you could specify LNM$PROCESS, which would be the equivalent of
 	specifying PROCESS.

 	Options for the MODE keyword are:

 	EXECUTIVE  Creates an executive mode logical name. You must have
 		   SYSNAM privilege to create an executive mode logical
 		   name.

 	SUPERVISOR Creates a supervisor mode logical name.

 	USER	   Creates a user mode logical name.

 	The access mode associated with the logical name is determined
 	by maximizing the access mode of the caller with the access mode
 	specified by the MODE keyword: the mode with the lower privilege
 	is used.

 	You cannot specify an access mode with a privilege higher than
 	that of the table containing the logical name. However, if your
 	process has SYSNAM privilege, then the specified access mode is
 	associated with the logical name regardless of the access mode of
 	the caller.

 	If you omit the MODE keyword, the access mode of the caller is
 	associated with the logical name.

 	If you create a USER mode logical name but don't specify a table,
 	the name will be deleted as soon as the LD control utility exits.
 	This is the normal behaviour for user mode logical names.
