Yes, and obviously don't declare it within the program (that's what appeared in the original example from Marc Pertron) - your example is indeed better from this point of view. I'd add that the disadvantage of ReadLn (used by you) is that it shows typed characters on console and in addition, I believe that these characters might be temporarily stored in a buffer in memory too (before they get overwritten with following input).
