MOD still gives a zero answer on multiples of -10, i.e.,
IF X MOD 10 = 0 Then makebossappear(cool, powerfull, supemissiles)
will still work at -10, -20, etc, for multiples of 10
the thing I don't like of mod is that it does not work for negative numbers: when I write "-7 mod 10" I expect to get 3, not -7.
