    Not sure what you mean by structure. Clarify?

    Each TSO user, batch job, or system started task runs in a separate address space. The operating system manages the memory and uses part of it for its own use. The rest of the memory is 'private' and can be used by your TSO or batch program. They can all be running simultaneously, but each one thinks they have the entire use of system memory.

    Storage is described in Init and Tuning Guide here:
