            GUI\PANEL "Title" HelpFile [/DETACH] [/LOG LogFile]
            GUI\PANEL [HelpFile] /CLOSE

        Activate  the  Graphic-User-Interface input mode for variables. A window
        with the specified title is created, but not mapped to the screen.  Suc-
        cessive LET commands will create widgets in this window to allow to mod-
        ify variables by entering values in the widgets.  Command  GUI\GO  "Com-
        mand"  will map the window to the screen. Once the proper input has been
        defined, clicking on the "GO" button will setup all  the  related  vari-
        ables  in the main program, and execute the associated command. Clicking
        on button "UPDATE" will only set  the  variables.   Clicking  on  button
        "ABORT" will return without modifying the variables.

        Help  is  available  in  the  window through the "HELP" button, but also
        clicking in any prompt area.

        See LET command for details.

        If option /DETACH is present, a menubar is created instead of  a  normal
        window.  Several  buttons  can  be  attached  to  this menubar using the
        GUI\BUTTON and GUI\MENU commands, but no variables can be  set  in  this
        mode. The menubar is mapped when command GUI\GO is typed.

        If option /CLOSE is present, the last detached menubar, or the specified
        one, is deleted.

        /LOG option stores variable definitions in specified log file.
