Data set header
An NJE job begins with a job header, is followed by data, and ends with a job trailer. The data between the job header and the job trailer can be either SYSIN or SYSOUT data.
An NJE SYSIN job contains JCL for a job and one or more SYSIN data sets. It might contain data set headers. If the SYSIN data set has record characteristics other than 80-byte fixed records, then it is preceded by a data set header containing only a record characteristics change section. See Record Characteristics Change Section.
An NJE SYSOUT job contains one or more SYSOUT data sets. Each SYSOUT data set is preceded by one
or more data set headers. A data set header contains a prefix section and a basic general section,
which might be followed by any of the following sections:
- General Section -- for SYSOUT from all products.
- RSCS Section -- for SYSIN from JES2, POWER, and AS/400.
- 3800 Section -- for output to be printed on a 3800 printer.
- Output Processing Section -- for advanced function printing 1 output.
- Security Section -- for resource authorization control.
- Product Section -- for output created at a VM/RSCS or a VSE/POWER node.
Table 1 describes which sections in the header are built and used by each subsystem.
