The SYSLIB DD statement is required if your program has external references that have not been resolved explicitly, unless you have specified the NOCALL option. This DD statement describes the automatic call library, which must reside on a direct access storage device. The data set must be a library and you must not specify member names. You can concatenate any combination of object module libraries and program libraries for the call library. If object module libraries are used, the call library can also contain any control statements other than INCLUDE, LIBRARY, and NAME. If this DD statement specifies a z/OS UNIX file, you can specify either a z/OS UNIX archive library or a PATH parameter that designates a directory.

The required data characteristics for object module libraries are the same as those shown in Table 1. For program libraries, a record format of U is required. For partitioned data set program libraries, the maximum block size is equal to the maximum for the device used, not the record read. For PDSE program libraries, the block size is 4 KB. You do not specify a value.

The binder does not support z/OS UNIX files as part of a concatenation.
