Explanation
(MVS, VM, and VSE) The named module made a service request that contains an invalid or unsupported code in the function request flag (FRF) or the function control flag (FCF).
System action
EREP ignores the request and returns control to the calling module at the specified return-point address (RPA). Register 15 contains the return code.
Programmer response
There is an error either in the product-dependent exit module or in the product control table (PCT) for the product. Make sure EREP support is installed for the products included in the module name.
