Hey Neil,
-1 is boolean for true in CF (and in most languages I've dealt with),
therefore doing the boolean test "not compare()" is a valid boolean
comparison for all three results of compare().

This not what I am saying...
0 = False
Not 0 = True
Not 1 = False
What I am saying is that Compare() can yield 3 return values....-1,1 or 0
and by saying <cfif NOT Compare(..)> you are checking for a Boolean value...
-1 is not Boolean.

>>Compare can return -1,0 or 1 which is not Boolean.
In almost any language, 0 is false and not 0 is true, boolean or not.
Even in C which is strongly typed.
