-2 147 483 648  and +2 147 483 647 are not the largest possible
magnitide 10-digit numbers.

9,999,999,999 and -9,999,999,999 are 10 digit numbers which fit in pic
s9(10) but not in a 32-bit int.

So s9(10) comp *is* too big for int32. Though not all values you might
put there are necessarily too big.
