GPR_$LIGHT_PFK_BUTTONS            GPR Calls             GPR_$LIGHT_PFK_BUTTONS


NAME
     gpr_$light_pfk_buttons - turns the PFK button lights on or off.

FORMAT
     gpr_$light_pfk_buttons (key_set, on_off, status)

DESCRIPTION
     This routine turns the lights on the specified LPFK buttons on or off.

     In FORTRAN or C, you must use lib_$init_set and lib_$add_to_set to create
     the keyset.  These calls are documented in Programming with General Sys-
     tem Calls.

     Specify an event type of gpr_$pfk in the gpr_$enable_input routine to
     enable LPFK events.

   Input Parameters
     key_set
          The set of function keys to light or turn off, in gpr_$keyset_t for-
          mat.

     on_off
          Specifies whether to turn the lights of the specified keyset on or
          off.   This is a boolean data type in Pascal and C, and a LOGICAL*1
          data type in FORTRAN.

   Output Parameters
     status
          Completion status, in status_$t format.
