Cause . . . . . : The NULL-KEY-MAP phrase should be specified on an I-O statement for a file containing the ALWNULL attribute in the ASSIGN clause if the file has null-capable key fields. Null-capable key fields will be processed as NOT null; that is the null key map will be set to ALL B"0".
Recovery . . . : Add the NULL-KEY-MAP phrase to the I-O statement.
