      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].
