plbop: Begin a new page
      Begins a new page.  For a file driver, the output file is opened if
      necessary.  Advancing the page via pleop and plbop is useful when
      a page break is desired at a particular point when plotting to
      subpages.  Another use for pleop and plbop is when plotting pages
      to different files, since you can manually set the file name (or file
      handle) by calling plsfnam or plsfile after the call to pleop
      (in fact some drivers may only support a single page per file, making
      this a necessity).  One way to handle this case automatically is to
      page advance via pladv, but enable familying (see plsfam) with a
      small limit on the file size so that a new family member file will be
      created on each page break.
