      SUBROUTINE PGEBUF

 A call to PGEBUF marks the end of a batch of graphical output begun
 with the last call of PGBBUF.  PGBBUF and PGEBUF calls should always
 be paired. Each call to PGBBUF increments a counter, while each call
 to PGEBUF decrements the counter. When the counter reaches 0, the
 batch of output is written on the output device.
