I am sure I shouldn't be helping you in your quest for oblivion, but
one of the few changes between Mosel<2 and Mosel2 is that you must
use :: in place of := in table assignments e.g.
t ::[8 , 6, 6, 6, 7, 4, 3, 3, 5, 7,
etc.

BTW: you get a week's units of alcohol all in one go as the answer
(assuming a) you are in the UK, and b) your name implies you are
female)
