PGPLOT Module: PGBBUF -- begin batch of output (buffer)
SUBROUTINE PGBBUF
Begin saving graphical output commands in an internal buffer; the
commands are held until a matching PGEBUF call (or until the buffer
is emptied by PGUPDT). This can greatly improve the efficiency of
PGPLOT. PGBBUF increments an internal counter, while PGEBUF
decrements this counter and flushes the buffer to the output
device when the counter drops to zero. PGBBUF and PGEBUF calls
should always be paired.
Arguments none
