Changing formatting within a document

In the examples in Specifying and selecting fonts, the same formatting specifications are used for all the pages of the line data set. But suppose that you want to change some of the formatting in the middle of your data set. For example, suppose that you want some pages printed at six lines per inch and other, summary pages printed at 8 lines per inch.

To change page definition options, such as print direction, line spacing, or record formatting in a print job, you need to use a page definition that contains multiple page formats. You also must tell PSF when to use which page format. For an example that shows how to do this, see Using multiple copy groups or page formats.
