It is my understanding that if you set the ARCH level to something lower than the machine type you are running on it should not use any of the new machine instructions. If what the vendor says is truly what is happening then I would think a question to IBM would be in order.

It also caused these abends when we were at COBOL 4,2, but the abend rate has grown considerably after the upgrade. The vendor has produced countless patches, but so far they have not resolved the issues. We were notified today that they believe they understand the issue. They are stating that even though our COBOL compiler is set with ARCH(8) (to support our DRE machine), LE run-time is recognizing that the program is COBOL 6.2, running on a z14, and automatically switch the ARCH level to ARCH(12). They believe the run-time execution is exploiting the new Vector Packed Decimal Facility and producing erratic behavior. I searched through several presentations and IBM manuals for COBOL 6.2, and everything I have found states that a recompile with ARCH(12) is required to take advantage of the new facility. Is the vendor correct?
