The parameters displayed in the Custom Check Digit Definition window must be defined.

The following section contains an explanation of each field:

∙Constant 2—A constant value in the range 0 through 99.

∙IA Digits—The digits comprising the Image Address. The Image Address may contain a fixed field as many as three level fields. The Image Address cannot exceed 11 data characters when accompanied by a check digit; the check digit occupies one character position.

∙Attributes—These are position weights for digits in the Image Address. A zero-value attribute causes the associated Image Address digit to be excluded from the check digit calculation. Each digit in the Image Address is multiplied by its attribute and summed. For example, if the Image Address is 1202.14.342.12 and you wish to calculate a check digit that excludes the fixed field (1202), the attributes (using Table 1) would be 00001546231.

NOTE: The “c” in Table 1 refers to the character position.
