Your program can invoke the GNRLFAIL/VSAMFAIL routine by using the LINK macro, specifying IKJEFF19 as the entry point name. However, you must first create the parameter list, then place the address of the parameter list into a fullword, and then place the address of the fullword into register 1.

GNRLFAIL/VSAMFAIL can be invoked in either 24- or 31-bit addressing mode. The caller's parameters must be in the primary address space. When invoked in 31-bit addressing mode, GNRLFAIL/VSAMFAIL can be passed input that resides above 16 MB in virtual storage.
