I had to find and fix some data like this. I used the following to
find the rows that had hex'40' in a particular field.
Select * from datafile where substr(trim(hex(orderqty)),1,2) = '40'
The TRIM scalar in the expression seems extraneous.? Regardless...
As I noted in prior responses, for the first byte of an odd-precision
Packed Decimal column, the value '40' is completely valid. The x'40' in
the first byte of storage for Packed BCD is legitimate, and therefore
should not be presumed to have originated as the EBCDIC blank x'40'.
