I think I can see the reason when I think about how a CPU has to handle an
operation such as DIVIDE. The values to be divided are moved in to a
couple of registers and when the operation is performed, it stores the
result in a register. To be certain of the value in the result register,
it's probably initialized to zero--just like I've seen explicitly done in
many programs. In this case the compiler seems to be doing it.

I don't have a copy of the COBOL 85 standard, but as far as the expected
ANSI behavior the latest standard to which I do have a copy lists a Fatal
exception named EC-SIZE-ZERO-DIVIDE specifically for 'Division by zero'.
I'll bet it's in the COBOL 85 standard also. Perhaps that could get IBM's

Given that there are probably COBOL programs on iSeries that depend
on the current behaviour, and that it's likely the expected ANSI
behaviour, . . . .
