A concealed logical is a type of logical name that conceals a part of the directory specification. The logical can then be used like a disk name. It is used to shorten and simplify file specifications as well as hide the directory structure from unprivileged users. In the following example, a concealed logical SUB is defined and used. Note the period at the end of the directory specification:
SMAN43$ define /sys /translation=concealed sub dsa1:[jdoe.sub.] SMAN43$ sh log sub "SUB" = "DSA1:[JDOE.SUB.]" (LNM$SYSTEM_TABLE) SMAN43$ dir sub:[000000] Directory SUB:[000000] B.LIS;1 ORIGINAL.LIS;1 SUB2.DIR;1 Total of 3 files.
Note that a concealed logical behaves like a disk; you have to use [000000] to go to the concealed directory itself. For example, when default is set to a concealed logical, it replaces the disk part of the specification:
SMAN43$ sh def DSA1:[JDOE] SMAN43$ dir sub %DIRECT-E-OPENIN, error opening SUB:[JDOE]*.*;* as input -RMS-E-DNF, directory not found -SYSTEM-W-NOSUCHFILE, no such file SMAN43$ set def sub SMAN43$ sh def SUB:[JDOE] %DCL-I-INVDEF, SUB:[JDOE] does not exist
