What is the starting position and length of the field that can be numeric or alphanumeric?
You didn't give me that information.
You show an INCLUDE with 100,1 which would imply that the field starts at position 100, but you show an example which implies that the field is in positions 1-3. It would be much easier to help you if you gave complete and clear information (especially when asked).
At any rate, you can select fields with only numerics using DFSORT's NUM function, e.g.
