Barbara said that she would rather that programmers had to specify the
length for all VARYING fields, because RPG is a strictly typed language.

Sure I would _rather_ that, but I can't _have_ that, due to
compatibility. If RPG's VARYING support changes, any existing code with
VARYING will continue to mean exactly the same thing in the future. If
you subtract 2 to get the size or add 2 to get the length, it will
continue to work. Cross and stamp and no erasies.

Again, you've explained this quite well, 'twas just my denseness that missed
it. But to be thorough, there is still the issue that large fields will NOT
work with a hardcoded "2". If the field is ever changed to be longer than
64K, then code that uses "2" will break.
