Tamar,

>> Even though Tamar has indicated that there's an order of magnitutde difference between using a FOR...ENDFOR construct over a DO WHILE, I don't necessarily believe that it would apply in all cases. While her remarks were directed towards VFP 7.0 and above, in VFP 6.0 it took in excess of 10,000,000 iterations before more than 1/10th of a second was realized. <

Indeed for an empty loop, but as soon as you are going to anything with it and place a condition into the FOR loop with an EXIT, the difference is far less convincing.
