PAGENUM

The PAGENUM option holds the current page number of output. You can use PAGENUM with PAGEPRG to produce the page number on each page of a report. The PAGENUM option is meaningful only when PAGING is set to YES and only for output from statements such as REPORT and LISTNAMES.

Data Type

INTEGER

Syntax

PAGENUM = n

Arguments

n

An INTEGER expression that specifies the page number to use for the next page of output. The default is 1.

Notes

Starting with Page 1

When you are sending output to the default outfile, set both PAGENUM and LINENUM to 1 whenever you want to produce a report starting on page 1. You can set these options in the initialization section of your report program. When you use an OUTFILE statement to send output to a file, PAGENUM is automatically set to 1.

Setting PAGENUM in Mid-Page

The value of PAGENUM is incremented automatically when the last line of output has been generated on a page. When you set PAGENUM when an output page is only partially full, the value of PAGENUM will be incremented by 1 before the next page is produced. This means you usually have to set PAGENUM to a value of one less than the number you want to show on the following page.

The Effect of PAGING on PAGENUM

When you set PAGING to NO, PAGENUM stops counting and keeps its last value. When you reset PAGING to YES, PAGENUM resumes counting at the page number where it left off.

The Effect of OUTFILE on PAGENUM

When you use an OUTFILE statement to direct output to a file, PAGENUM is set to 1 for the file. When you use an OUTFILE statement with the EOF keyword to redirect output to the default outfile, PAGENUM will contain the number that it last held for the default outfile.

Examples

Example 6-84 Changing the Heading for Page 2

Suppose you want each page of a report to have a standard running page heading and a custom title, and pages after the first page to also have the heading "(Continued)". You can define a page heading program called report.head that uses the PAGENUM value to determine when to add the "(Continued)" heading.

DEFINE report.head PROGRAM
PROGRAM
STDHDR
BLANK
PAGING = YES
HEADING WIDTH LSIZE CENTER 'Annual Sales Report'
BLANK
IF PAGENUM GT 1
   THEN HEADING WIDTH LSIZE CENTER '(Continued)'
BLANK
END

In your report program, set the PAGEPRG option to use the report.head program.

PAGEPRG = 'report.head'

When you run the report program, each page after the first page starts with a heading such as the following.

15JAN95 15:05:16                                      Page  2
                       Annual Sales Report
 
                           (Continued)
