Name: PGBBUF Purpose: begin batch of output (buffer) Category: GRAPHICS File: pgplot.src Author: T.J. Pearson Use: see description below. Description: 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 Updates: Oct 16, 1998: JPT automatically extracted from source.
