Now use it in a numeric constant. $s += 1;

$s += 1 does more than "use it in a numeric context".

Update:

Furthermore, even though you went outside the scope of the question, the scalar still has a numerical value throughout.

  FLAGS = (NOK,pNOK)
  FLAGS = (NOK,POK,pNOK,pPOK)

There is no such terminating condition.
