Re: File keyed on a date field: the read doesn't actually get anything! What am I doing wrong?

[Brian Parkins <goodprophet.bp@xxxxxxxxx>]

We'd need to see a little more code to be able to help, James - to avoid 
make incorrect assumptions.

Thoughts that come to mind:

- Is keyed processing defined on the F-spec?
- What is the actual value of JAN31 immediately before the SETLL?
- Have you inspected the data to confirm there are rows which should be 
read?

HTH
