Most compilers have their own automatic call libraries, which can contain input/output, data conversion, or other special routines needed to complete a module. Other products provide assembler and compiler preprocessors that generate calls to such routines in your program. You and your organization can provide additional libraries. When an object module is created, the assembler or compiler creates an external reference for these special routines. The appropriate library must be defined when an object module produced by a particular assembler or compiler is bound; the binder resolves the references from this library.

See the appropriate user's guide for the name of the call library.
