Base Section

z/OS MVS Programming: JES Common Coupling Services
SA23-1387-00

The base section is the same for all exits; it specifies:
  • Under which JES the exit was called
  • The version of the parameter list presented to the exit
  • The size of the base section
  • The total size of the parameter list
  • Optionally, a pointer to a shared data area created by exit IXZXIT03.

When exit routine IXZXIT03 receives control, it has the option to create a data area. If exit routine IXZXIT03 creates the data area, exits IXZXIT01 and IXZXIT02 can use the data area to share data such as constants, pointers, and so forth. If exits IXZXIT01 and IXZXIT02 need to share a data area, your installation routine is responsible for the creation of this data area and its content.
