Wouldn't it be easier to upgrade to a more recent release?
Easier support for varying length fields was added in V4R2.
In V3R7, you'd be writing code that will be quickly
obsolete anyways!  Also, putting too much of a dependency
on CVTOPT(*VARCHAR) will only make using real character
varying fields more difficult.
