plbop
( | ) ; |
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
by calling plsfnam
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.
Redacted form: plbop()
This function is used in examples 2 and 20.
