1.Read the file sequentially
2.For every successful read, move the key field to temp variable
3.when EOF is reached, A separate section should be performed in which Key field should not be moved to temp variable, Now, the temp variable will have key of the previously read record.
Using this, we can do a keyed read on the file to fetch the last but one record.

I have a program with an Array of 5000 occurences which is being passed from 5 sub levels to the front end screen. Thess 5 programs using each 5*2 = 10 different arrays with size as 5000. This is causing the transaction to utilize more storage consupmtion. I am looking to reduce the storage consumption. As part of that initially i thought Dynamic array may solve my problem. After viewing the comments given i see its same as normal array. IS there any other way we can resolve this issue?
