Well, safety is still important. You should use the returned count in your 
procedure to be on the safe soide. The end might come sooner than expected.

So, to be on the safe side, for a little tradeoff, include the returned 
"count" value in your algorithm, which will make your program womewhat 
slower, but still faster than it was before.

Will you run the program somwhere in some safe environment? Because there 
might still be errors in it .. I didn't have the time yet to read it 

Bye Anton.
