Explanation
(MVS) IOS indicates an attempt has been made to read outside the extent on SERLOG (SYS1.LOGREC). The LOGREC header may be bad.
System action
EREP continues processing. The record that has caused the input error is ignored. SYS1.LOGREC is not cleared.
Programmer response
Obtain a copy of the header record to verify the contents of the header. Determine if the problem is caused by a hardware malfunction. If the message does not recur, there probably is a hardware error on the device (or volume). Otherwise, it is probably a programming error. Execute the IFCDIP00 program to reinitialize SYS1.LOGREC.
