Re: QUSLFLD

Maybe you're just not looking at the right place for this being documented.
Do you suppose that someone doing a client server package calls that API
and processes the user space?  No, there are some SQL calls that will
return the structure of a table.  Granted I don't know all of this.  Maybe
our visual basic odbc brethern are better versed - but then again maybe
it's buried in the ODBC driver itself.

I would add to this that I have seen a couple of occasions where the IBM
reference files were "out of touch with reality" requiring a RCLSTG DBXREF;
I presume this would also impact using this file as the basis of your
procedure whereas IMO the API would continue to work. Admittedly an unusual
circumstance, and maybe I have misunderstood what I actually rebuilt.

Also, in line with James' comments I would be nervous about using an
undocumented/informal method as opposed to an officially support interface.
It seems to me this has similarities with hard-coding off-set or other
values in API calls.....

Just another opinion
