How to define page up and page down in map ? If there are 100 records and I need to throw only 10 at a time?
As per my understanding I need to use READ ISN for the file. Read first 10 records and save *ISN of last record. Create two separate subroutines for PAGE-DOWN and PAGE-UP.
If PF8 is pressed Perform PAGE-DOWN. In PAGE-DOWN subroutin, do READ ISN from the stored ISN
IF PF7 is pressed Perform PAGE-UP. But here I have no idea how to read file in reverse order.
Please help on this. Is my approach is correct or there is any other way. I remember I had created such application in past around 6 years back. But now can recall.
