Use of "TRIM" in DDS Logical File declaration

When building a Logical File Definition using DDS ...

... SST is the SUBSTRING function
0009.00      A            WHOOWNS            I      SST(TLTBLS 26 5)

That's great ... but ...
I need the WHOOWNS field value LEFT SET and LEFT TRIMMED
Because SST(TLTBLS 26 5) actually evaluates to "  XYZ" and "    A" and "   ZA"

No one else has responded, so I'll do what I can. If I'm wrong, someone's bound to catch it and we'll both learn something.

The answer seems to be "You can't." If I were doing this, I'd probably create a SQL VIEW with a DDL statement rather than try to get it done with DDS.

However, it might help if you describe the business use for this. Usually, the reason for going with DDS would be to support a compiled language such as COBOL, RPG, C, etc., where native I/O was a requirement. But those languages already supply functionality for substrings, left-adjusting, trimming, under more precise control.

Can you provide the environment within which this field definition is needed?
