handling page up in single page subfile

Question

i am unable to handle page up option in single page sub file ....dont know how to go back to the previous rrn so that previous page can be displayed ....

Answer 1

The required logic is:

• Check the indicator of the rolldown key
• If that indicator is true, then clear your subfile
• Your file pointer must go 13 (of whatever) rows back. Do that with readb, setll, chain and recordnumber, or something else (that is up to you)
• Rebuild your subfile

DON'T FORGET to reset your subfile number!!!!!!!!!!!

For small files, building the complete subfile at once and let the iSeries do the handling is much easier.
