A diagram shows the relationship between the object decks and the load module stored in a load library, and then loaded into central memory for execution.

In Figure 1, we can see the relationship between the object decks and the load module stored in a load library, and then loaded into central memory for execution.

We start with two programs, A and B, which are compiled into two object decks. Then the two object decks are linked into one load module call MYPROG, which is stored in a load library on direct access storage. The load module MYPROG is then loaded into central storage by the program management loader, and control is transferred to it to for execution.
