X\descr{Advances to the next subpage if {\tt sub=0} or to the specified
Xsubpage
Xif {\tt sub} is non-zero. This routine is called automatically (with

Xby {\tt plenv}, but if {\tt plenv} is not used, {\tt pladv}
X must be called after {\tt plstar}
Xbut before defining the viewport.}

X\addcontentsline{toc}{subsection}{plbeg}
X
X\descr{Alternative to {\tt plstar} for initializing the plotting package. The
X device number of the desired output device must be supplied as
X an argument. The mapping from device numbers to devices varies
X from one implementation to another, and so use of {\tt plstar} which
X prompts for the device type is recommended. The device codes are
X the same as those printed out by {\tt plstar}. This routine also divides
X the output device into {\tt nx} by {\tt ny} sub-pages, each of which may
X be used independently. The subroutine {\tt pladv} is used to advance
X from one subpage to the next.}
