Description:

            SUBROUTINE GRESC (TEXT)
      
       GRPCKG: "Escape" routine. The specified text is sent directly to the
       selected graphics device, with no interpretation by GRPCKG. This
       routine must be used with care; e.g., the programmer needs to know
       the device type of the currently selected device, and the instructions
       that that device can accept.
      
       Arguments: none.
        TEXT (input, character*(*)):  text to be sent to the device.

       19-Dec-1988 - start new page if necessary [TJP].
        4-Feb-1997 - RBUF should be an array, not a scalar [TJP].
