is a 1991 or later release, based your 1991 book David. We really need to know the serial number of Norm's book to see how it fits into the sequense of releases'. Usually a pubisher will note 1st edition printed xx-xx-xx, 2nd edtion printed zz-zz-zz, etc. and Borland did not do that.

So what is needed is the serial number of the book, plus any price list with a date, and hopefully an edition number, to form a bases for determining what had been released, isn't this true?
