Defining the primary input

The primary input, required for every binder job step, is defined on a DD statement with the ddname SYSLIN. Primary input can be:

A sequential data set
A member of a partitioned data set (PDS)
A member of a partitioned data set extended (PDSE)
Concatenated sequential data sets, or members of partitioned data sets or PDSEs, or a combination
A z/OS UNIX file.

The primary data set can contain object modules, control statements, load modules and program objects. All modules and control statements are processed sequentially and their order determines the order of binder processing. The order of the sections after processing, however, might not match the input sequence.

The following examples show the statements needed to define input to the binder.
