This exit allows you to change an NJE data area before transmitting a job to another node through TCP/IP NJE. (See Network Job Entry (NJE) Formats and Protocols for more information about the various NJE data areas that can be transmitted across a network.) Before transmitting the NJE job, your installation might need to add, remove or change information to one or more of the following NJE data areas:

• NJE job header
• NJE data set header
• NJE RCCS (Record Characteristics Change Section) header
• NJE job trailer

Your installation might want to:

• Remove any installation-defined sections your installation added to the NJE job when exit 56 was processing the NJE job. However, it might not be necessary to remove any installation-defined sections because installation-defined sections are ignored when they are received at other nodes.
• Add or change information, such as accounting, security or scheduling information, needed by another node in the network.
• Extract information from user fields in JES2 defined control blocks or installation defined control blocks and transfer them to the NJE data areas.
