      SUBROUTINE GRGE03(QBUF,ICNT)
C
C GRPCKG (Internal routine): Write ICNT bytes in QBUF onto logical
C unit LUN.  Reset ICNT to zero.
C Based on GRxx03 routines, this version does not contain a common
C block.
C ***NOTE*** INIT03 must be called before any calls to GRGE02 to
C set the LUN/Channel to which the buffer should be dumped.
C This subroutine contains the entry point INIT03 that defines
C the variables ITYPE, LUN and IFUNC.  If ITYPE=0 then LUN is
C the Fortran logical unit number to which the data should be
C written.  If ITYPE>0 then LUN is the Channel number for a QIO
C operation and IFUNC is the QIO write function.
C
C Arguments:
C
C QBUF            I/O Byte The output buffer.
C ICNT            I/O I    Current number of bytes used in QBUF.
