                 Summary: doc command fails to return an output value when run

                 Project: GNU Octave

                Severity: 2 - Minor
                Priority: 5 - Normal
              Item Group: Incorrect Result
                  Status: None

         Discussion Lock: Any
                 Release: dev
        Operating System: Any

    _______________________________________________________

Details:

When the GUI is disabled, running


r = doc ("help")


returns a status value in r (usually 0).

When the GUI is running the same command produces a warning


r = doc ("help")
warning: doc: some elements in list of return values are undefined
warning: called from
    doc at line 121 column 1
r = [](0x0)


The fix will be probably be in octave-link.cc
