Description
You can use $page to assign the page number to fields in header or footer frames.
If you are not printing, it returns zero when used in the getFocus trigger of a header or footer frame.
Using $page
The ProcScript in the following example assigns the page number to the dummy field REPORTPAGE in the footer frame. The footer frame has the Suppress Print if Empty property selected, which means that it does not appear if REPORTPAGE has no value.
The first page of the report is a cover sheet that is not numbered; subsequent pages are numbered starting at 1. Because of the unnumbered page, the value of REPORTPAGE is one less than the value supplied by $page.
trigger getFocus ; of footer frame
if ($page = 1) ;if on first page done ;take no action
done
else
REPORTPAGE = $page - 1
endif
end
