Hi Elvis

There are non-numeric code points that have 'F' in the first nybble, so the test might have to be expanded to exclude (include?) A to F.

Not overly ugly for a one time thing... perhaps:

or

select rrn(a),hex(myField), f1 from myLib/myFile a where 'F' not in (substring(hex(myField), 1,1), substring(hex(myField), 3,1), substring(hex(myField), 5,1), substring(hex(myField), 7,1), substring(hex(myField), 9,1), substring(hex(myField),11,1), substring(hex(myField),13,1)) AND
substring(hex(myField),15,1) not in ('F','D')

Subject: Re: Finding invalid data in zoned numeric fields with SQL

Elvis,

Nice thought! The concern I have is if the first position of the field has
an "F" value in the left nibble for that byte, that does not mean the rest
of the field has valid values. I think I am going to have to test all bytes
for valid values, if SQL does not have nice function to do it for me. That
could get a little ugly with an 8 digit field.

Yes - I believe the software vendor did create this with DDS, and even
thought it is defined as Zoned, it somehow allows invalid data to be added
to the file in 4 fields.

Thanks!

Jim
