A J2 dataitem is identical in format to an I2 integer, the only difference is
that the range is limited to an "even" decimal series (the largest power of
10 that will fit under 2**31). However, IMAGE doesn't enforce that rule. In
fact, IMAGE enforces virtually no rules at all about how data is stored in
the database. It's essentially up to the application to enforce the
COBOL-specified artificial range restriction.
