Interface Definition Files (IDFs) for APPC/MVS Services

IBM provides IDFs (also called pseudonym files or headers) that define variables and values for parameters of APPC/MVS services. IDFs are available for different languages, and can be included or copied from a central library into programs that call APPC/MVS services.

For a list of the IDFs available for use with CPI-C, LU 6.2, and APPC/MVS services, see z/OS MVS Programming: Writing Transaction Programs for APPC/MVS.

IBM provides the following IDFs for programs that call APPC/MVS allocate queue services, the Reject_Conversation service or the Set_Conversation_Accounting_Information service:
