Object library utility

The object library utility is used to update libraries of object modules. A library is a partitioned data set (PDS or PDSE) with object modules as members

Object libraries provide for convenient packaging of object modules. With the Object Library Utility, a library can contain object modules with L-names, object modules with S-names, and object modules with writable static data. The Object Library Utility is used to create information, such as which members contain defined L-names, S-names, or writable static data. This information is stored in a special member of the library that will be referred to as the Object Library Utility directory.

Commands to add object modules to a library, to delete object modules from a library, or to build the Object Library Utility directory for a library are available. Use the DIR command to build the Object Library Utility directory for a library of object modules. Use the MAP command to list the contents of the Object Library Utility directory.
