The key generator utility program attempted to generate a key for a control statement and either a problem occurred with the time-of-day (TOD) clock or a valid seed value was not supplied on the EXEC statement. Message ICU1018, which identifies the specific problem, and the control statement being processed when the problem occurred, precede this message.
Rerun the key generator utility program specifying the CHGK function on the EXEC statement and providing the control statement that was being processed when the problem occurred.
