Return area and function call EQUATE copybooks

CICS® provides four language-specific copybooks that map the storage areas for the return_area and dpl_retarea parameters of the EXCI CALL commands. The copybooks also provide EQUATE statements for each type of EXCI CALL.

These copybooks, and the libraries they are supplied in for the supported languages, are shown in Table 1.
