OTMA Callable Interface API calls

Using the Header File DFSYC0.H:

The header file included in the API calling program declares each API invocation and variables used for the invocation.

For a C/C++ program using OTMA Callable Interface, the C/C++ header file, DFSYC0.H, needs to be included in the C/C++ program.

Load Module DFSYCRET:

The object stub, DFSYCRET, receives all the API invocations and issues a SVC call to perform the requested function. The object stub needs to be available during the binding of the API invoking program. DFSYCRET can be found in SDFSRESL or ADFSLOAD data sets.
