APAR status
Closed as program error.
Error description
In 64-bit mode, if user attempts to write more than 2**31 bytes in a single unformatted record using the default value for the UWIDTH option (32), no error is emitted, and the record marker will overflow.
Local fix
The program should be run with UWIDTH=64. If that's done, there is no error and no overflow.
Problem summary
In 64-bit mode, if you attempt to write more than 2**31 bytes in a single unformatted record using the default value for the UWIDTH option (32), no error is emitted, and the record marker will overflow. The cause of the problem is that with UWDITH=32, the record marker used by XLF is a 4 byte signed integer. It therefore imposed a record limit of 2**31 - 1. Programs that require larger records must use the UWIDTH=64 option which uses 8-byte records.
Problem conclusion
The problem had been fixed.
