Subj: BAR CODE BOOK

I'm trying to research your question on the 'Z'.  Meanwhile, I obtained a copy
of "THE BAR CODE BOOK   Reading, Printing and Specification of Bar Code
Symbols" By Roger C. Palmer.  It has got to be the most comprehensive book on
all bar codes that I have ever seen, and it just appeared on the local 'Half
Price Books' shelf!  The ISBN is 0-1911261-05-2 (paperbound), and the publisher
is Helmers Publishing, Inc.  174 Conord Street Peterborough, NH  03458.  I
really suggest you acquire this book if at all possible.  My hunch regarding
'Z' at first guess is related to a timing sequence between the bars.  I'm going
to try and ferret out an explanation for you if I can decipher all this
technical info in the book.
