4118D FILE ID ERROR, READBK filename SYSxxx=cuu
Cause: Read backward was specified and an error was detected in checking the trailer label.
File ID field does not match with the information in the tape label statement.
System Action: This message is followed by the trailer label file identification of the last tape
record read. If SYSLOG is assigned to a keyboard, the system waits for an operator response;
otherwise, the job is canceled.
Programmer Action: Check the TLBL statement for errors in the file ID and check that the
tape was not repositioned before the read backward OPEN was issued. Check that the
program that built the file or processed it in a forward read did not request a rewind during
CLOSE. Check that the failing OPEN statement has the correct filename. Make the necessary
corrections and resubmit the job.
If the problem recurs, have the
· system dump at the time of the failure
· job stream
· program listing
· log sheet
· printer output
available for problem determination.
Operator Action: Type CANCEL or press END/ENTER to cancel the job, or
Type IGNORE to continue processing if the label information is not needed.
