Thank you, Per. I checked the length and it was 255! It turns out that
database field was 255 characters! I changed the database definition to
varchar(255) (this is Oracle), which it should be anyway, and then we get a
value that is trimmed to the right size.

Not a Scheme problem at all. THANK YOU!!
