That 2006 email demonstrates why adding long string support to Base 3.14.12 in
2010 was important; it allows link addresses longer than 40 characters to be
written to link fields at run-time, thus enabling sites to use record names
longer than 28 characters without compromising their ability to modify the
database configuration on the fly. Client programs do have to be able to
detect and use the long string semantics though, and developers need to
remember to append a '$' to the field name when accessing link fields though.
