True, but that would be the case no matter how the VARYING > 65535 was
handled. The programmer who changes the length over the 65535 mark and
gets an immediate syntax checker or compiler diagnostic about VARYING(4)
being required has a better (imo) chance of spotting this problem when
they do their impact analysis. If the compiler silently defaulted to
VARYING(4), the programmer might be less aware of the extra impact
analysis required due to the change in both the length and the prefix
length.
