Right you are robot - I was looking at a 1988 book (obviously not going to find a 1990 code there!!) - and that, my friends, is why CHR is the best source because we're all always "learning" something new!

As to Mortec - I stopped using them a while back when their web site went down and just never re-bookmarked them. I agree they've gor a few "holes" in their data base.
