ISBN is an .ACC and a .PRG by Mark Brinkworth in which he does it
again (dated May 31, 1994)! He wrote VERICARD which tells you whether
or not a credit card number is valid. Now with ISBN2 you can tell is
the ISBN #'s in the front of every book is valid or not. I've tried it
with several books and they all come back as valid numbers (when would
you ever find an INvalid number?). Anyway, it's interesting to find out
that there is an inter-relationship between the numbers in an ISBN #.
Color or mono. Geneva compatible. Docs included.
