Brian mentioned it, but I'll expand: you need to check *all your
processing*, to see whether and where you might copy data from that
field into a dummy variable, and expand those variables -- and check to
see if any code that touches them makes assumptions about their length
(MID functions, most notably).

It's not an easy job.  :-}
