Callable interface in CICS

If you are migrating from QMF Version 3.1 or later, the interface between the QMF-supplied function call and the main QMF program has changed from a CALL interface to an EXEC CICS LINK interface. The new interface provides better isolation from the user program and the QMF product. Because the interface has changed, it is necessary to relink-edit your programs that use the callable interface.
