Program linking

A LINK command is used to pass control from an application program at one logical level to an application program at the next lower logical level.

Application program logical levels
Application programs running under CICS are executed at various logical levels. The first program to receive control within a task is at the highest logical level.
Link to another program expecting return
If the program receiving control is not already in main storage, it is loaded. When a RETURN command is processed in the linked program, control is returned to the program initiating the link at the next sequential process instruction.
