Nope, jump right in.

The FOR ENDFOR construct is used when the number of iterations is known in advance. DO WHILE is used when there is a conditional test. Even if one is faster than the other, you cannot always apply both, so your example isn't a straightforward comparison. This is a good example of what I'm talking about. We should know which commands to use and when. If the the number of iterations is known, would you write DO WHILE lnI .Signature { margin-top: 12px; color: #666666; } .Signature a { color: #666666; }
