Interface Definition Files (IDFs) for LU6.2 and APPC/MVS Services

APPC/MVS provides IDFs (also called pseudonym files or headers) which 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 invoke APPC/MVS callable services. The following IDFs are available on MVS:

For a list of IDFs for CPI-C calls, see Interface Definition Files (IDFs) for CPI-C Calls.

APPC/MVS provides the following IDFs for APPC/MVS conversation calls:
