Uh-Oh, yes I mixed up John's "Tool Kit" name with Ulrich's software. Sorry to both. I now see a clear disadvantage to my installing both into the same program files directory.

  Thanks for the good words, Don... note, however, that Ulrich may justly take
  exception to his EZGPIB program being conflated with a collection of ad-hoc
  utilities and hacks whose motto is "Every error is fatal." :)
