The output file has a record length of 100 defined in the program but a record of 60 bytes getting written into it. i.e. The rest of 40 bytes I am not Writing anything. But it by default puts some values into the last 40 bytes. However it does not impact anything. But when Compiled the module with Enterprise Cobol the last 40 bytes were spaces as fillers.

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?
