Coding is not possible in this forum. Here is the logic.
Suppose you want you display 10 items at a time on the
scren.
1 Declare an array of occurance 10.
2 Read-Next the file and load the records on Array.
3 Send data in the to screen.
4 If user pressed PF8. Take the last record(i.e. 10th in
our case) and perform READ-NEXT from last record onwards.
Store the records on array and send them to screen.
5 If user pressed PF7. Take the last record(i.e. 1st in our
case) and perform READ-PREV from first record onwards.
Store the records on array and send them to screen.
