  SET(WIDGET_CONTEXT_HELP)

  Specifies the widget within which context-sensitive help interaction will
  occur until the user clicks M1 on a widget.  Valid only in the Motif
  DECwindows environment.

  Syntax

     SET (WIDGET_CONTEXT_HELP, widget, {ON | 1 | OFF | 0})

  Parameters

     WIDGET_CONTEXT_HELP  A keyword directing DECTPU to enter the Motif
                          context-sensitive help mode in which the mouse
                          pointer changes to a question mark until the user
                          clicks M1 on a widget.  The mouse pointer then
                          reverts to the default pointer shape, and a help
                          callback is called on the selected widget (or its
                          parent if the selected widget has no help
                          callback).

     widget               The widget instance within which the modal help
                          interaction will be limited.  Applications will
                          normally specify the top level widget returned
                          from the GET_INFO (SCREEN, "widget") built-in.  A
                          help callback occurs only when the mouse is
                          clicked on the specified widget or any of its
                          children widgets.

     ON                   Confines the question mark pointer to the
                          specified widget.  If any children widgets have
                          been moved outside the specified widget's
                          boundaries, then the question mark pointer cannot
                          be moved to those children unless this parameter
                          is OFF or 0.

     1                    Same as ON.

     OFF                  Does not confine the question mark pointer to the
                          specified widget.

     0                    Same as OFF.

  Example

     The following statement enters context-sensitive help mode, and does
     not restrict the question mark mouse pointer to the boundaries of the
     top level DECTPU widget.  This lets the pointer be moved to the
     application dialog boxes that have been moved outside the DECTPU
     boundaries.

     SET (WIDGET_CONTEXT_HELP, GET_INFO (SCREEN, "widget"), OFF);
