PAGENO

Contains the current page number in a report.

Syntax

PAGENO

Usage

This operator takes no operand but returns the number of the page the report engine is currently printing.

You can use PAGENO in the PAGE HEADER or PAGE TRAILER block, or in other control blocks to number the pages of a report sequentially.

Example

If you use the SQL aggregate COUNT(*) in the SELECT statement to find how many records are returned by the query, and if the number of records that appear on each page of output is both fixed and known, you can calculate the total number of pages, as in this example:

  FIRST PAGE HEADER
    SELECT COUNT(*) INTO cnt FROM customer 
    LET y = cnt/50 -- Assumes 50 records per page 
  ON EVERY ROW
    PRINT COLUMN 10, r.customer_num, ...
  PAGE TRAILER
    PRINT PAGE PAGENO USING "<<" OF cnt USING "<<"

If the calculated number of pages was 20, the first page trailer would be:

Page 1 of 20

PAGENO increments with each page, so the last page trailer would be:

Page 20 of 20
