RE: Advise on a Database Change

I think the answer depends entirely on how certain you are that you know ALL
of the programs that reference this field.

In the past, I would have left the 10th field in place and changed its name
to UNUSED or some such.  I would have added the new field at the end.  The
reasoning behind this: we had many programs using SORT, and we didn't want
to change all of them.  Moving fields around changes the columns, which
ripples down to sort.

Modern times, it probably doesn't matter what you do as long as you can
locate all of the programs and all copies of the file.
