systems (UPC, EAN, ISBN, CreditCard, ...) The table below is a list of many
such numbering systems. You select a numbering system in the first column
and use the data in the row to its right to set the parameters in the Checkdigit
dialog box. (The box appears when you select checkdigit numbering in the Job
Setup dialog box.) These values are provided as a guide and their use should
be verified by you. numberED bears no responsibility if the information
