I have an issue where we have a PF with a field (door number, 5A) that
needs to be defined as a numeric field.

I have been asked to not use a SQL View which I have used using a CASE
statement to test for alpha, numeric or blanks. This works.

The manager wants it done in DDS in a logical file. As far as I can
remember this is not possible, but I want to verify before I take up the
subject with management.

TIA
