Example of Printing Headings on Every Page

The

allows

printing

headings on

Printing a Heading on Every Page

Example of Printing a Field on Every Page

Figure 158 on page 320shows the necessary coding for the printing of fields on every page; a skip to 06 is done either on an overflow c change in control level (L2). The NL2 indicator prevents the line from skipping twice in the same cycle.
