Hi,
I have doubt why all the load libraries(PDS) are created with record format as U.

Can anyone give some insight into it.

Thanks,

I'd guess because the record format of the modules is undefined.....

Hello,

Load libraries are of undefined format because the operating system requires it. This is not some decision made by the system support or operations people.

RECFM=U is better suited for the type of "data" that is stored in a loadlib. It is good to remember that your "executable" is just more data to the system internally - until it is loaded into core and control is passed to it.
