| "4" |
(record sequential files only) Indicates that a boundary violation exists. A possible violation is that an attempt has been made to WRITE or REWRITE a record that is larger than the largest, or smaller than the smallest, record allowed by the RECORD IS VARYING clause of the associated file. |
| "5" |
(all files ) An attempt has been made to REWRITE a record to a file, and the record is not the same size as the record being replaced.  For line sequential files this refers to the physical size of the record, that is after space removal, tab compression and null insertion. In this case, the physical size of the new record is allowed to be smaller than that of the record being replaced.
|
| "6" |
