Advances to the next subpage if sub=0, performing a page advance if there are no remaining subpages on the current page. If subpages aren't being used, pladv(0) will always advance the page. If page>0, PLplot switches to the specified subpage. Note that this allows you to overwrite a plot on the specified subpage; if this is not what you intended, use pleop followed by plbop to first advance the page. This routine is called automatically (with page=0) by plenv, but if plenv is not used, pladv must be called after initializing PLplot but before defining the viewport.

Redacted form: pladv(page)

This function is used in examples 1, 2, 4, 6-12, 14-18, 20, 21, 23-27, 29, and 31.
