Tamar,

Bruce Campbell and I did some work based on his code. That's where the numbers came from. Certainly, under other circumstances, the difference might be greater. Then again, we should always consider the circumstances.

In Bruce's case, using FOR...ENDFOR with an EXIT because the routine was time sensitive and encompassed a huge umber of iterations. There, it was certainly an appropriate choice. However, I don't believe that it applies to all cases.
