ABL Syntax Reference : PAGE-SIZE function
 

PAGE-SIZE function

Returns the page size (lines per page) of an output destination as an INTEGER value. If the output stream is not paged, PAGE-SIZE returns a value of 0.

Syntax

PAGE-SIZE [ ( stream | STREAM-HANDLE handle ) ]
stream
The name of an output stream. If you do not name a stream, PAGE-SIZE returns the page size of the default unnamed output stream.
STREAM-HANDLE handle
The handle to an output stream. If handle it is not a valid handle to a stream, the AVM generates a run-time error.

Example

This procedure prints a customer report categorized by state. At the end of each state category, it tests to see if there are at least four lines left on the page. The LINE-COUNTER function returns the current line number of output. If that number plus four is greater than the total number of lines on the page (returned by the PAGE-SIZE function), then the procedure skips to a new page. If there are four or more lines left, the procedure skips a line before printing the next customer record.
r-pgsize.p
OUTPUT TO PRINTER.

FOR EACH Customer NO-LOCK BREAK BY Customer.State:
DISPLAY Customer.CustNum Customer.Name Customer.Address Customer.City
    Customer.State.
IF LAST-OF(Customer.State) THEN DO:
IF LINE-COUNTER + 4 > PAGE-SIZE THEN PAGE.
ELSE DOWN 1.
END.
END.
