Chris...
Firstly - Flash doesn't have the concept of constants, so you couldn't
enforce a constant even if you wanted to (except by a hack like
defining a null set() function, but that's beside the point a bit)...
you can only suggest that specific things should be constant by
convention i.e. tell all your coders to treat variables in capitals as
constant and not to change their values.
Secondly - who knows? Those variables aren't actually referred to in
the code except for on their defining lines. They could be used for
absolutely anything at all. You'd need to be much clearer on the
purpose of those variables before anyone could tell you if they
'should' be constant. But see my first paragraph.
I could answer more fully if I knew why you were asking, and what the
values were actually supposed to be...
