PAGE HEADER
Defines the printing commands for the top of all pages of a report.
This control block is executed whenever a new page is added to
the report. The PAGE HEADER control block specifies
the action that the runtime takes before it begins processing each
page of the report. It can specify what information, if any, appears
at the top of each new page of output from the report.
The TOP MARGIN specification (in the OUTPUT section)
affects how many blank lines appear above the output produced by
statements in the PAGE HEADER control block.
You can use the PAGENO operator in a PRINT statement
within a PAGE HEADER control block to automatically
display the current page number at the top of every page.
The FIRST PAGE HEADER control block overrides
this control block on the first page of a report.
New group values can appear in the PAGE HEADER control
block when this control block is executed after a simultaneous end-of-group
and end-of-page situation.
The runtime system delays the processing of the PAGE HEADER control
block until it encounters the first PRINT, SKIP,
or NEED statement in the ON EVERY ROW, BEFORE
GROUP OF, or AFTER GROUP OF control block.
This order guarantees that any group columns printed in the PAGE
HEADER control block have the same values as the columns
printed in the ON EVERY ROW control block.
