Brian,

I think you need to take a look at the DDS manual.

4S 0 doesn't mean 'signed', it means zoned.

4  0 doesn't mean 'unsigned', it means packed (as does 4P 0).

In either case, zoned and packed fields are always signed.

The iSeries doesn't have an "unsigned" type for any files regardless of
if you use DDS or SQL DDL to define the file.

HTH,

Charles Wilt
