In the integer based calculations, I think that if one wanted to make larger lengths, you needed to minimize the charsets. Which if I remember correctly to say make it from 32->126 to 32->255 the length would need to decrease by an amount to keep it from overflowing (length 5 off the top of my head.) Thanks for the rest of the explanation, it clarified other questions I had. > -- Stephen J Smoogen. "The core skill of innovators is error recovery, not failure avoidance."
