Sweet Sixteen 
-- HOW TO BEGIN --
-GENERAL solving HINTS-
Remember that every letter MUST have a
different value.
So if you have already found beyond doubt
that O=19
Then NO OTHER LETTER CAN TAKE THAT VALUE.
Letter values can be ONE or TWO digit values.
(that is the hardest part to grasp with
Alphanumeric Puzzles)
Progress by always carefully selecting the
next BEST word:
Usually a word with the most already established letters-values
included
