The font style of the interpretation line depends on the modulus (width of narrow
bar) selected in ^BY:
6 dot/mm printer: A modulus of 2 dots and greater will print with an OCR-B
interpretation line; a modulus of 1 dot will print font A.
8 dot/mm printer: A modulus of 3 dots and greater will print with an OCR-B
interpretation line; a modulus of 1 or 2 dots will print font A.
12 dot/mm printer: A modulus of 5 dots and greater will print with an OCR-B
interpretation line; a modulus of 1, 2 or 3 dots will print font A.
24 dot/mm printer: A modulus of 9 dots and greater will print with an OCR-B
interpretation line; a modulus of 1 to 8 dots will print font A.

Comments: The UPC-A bar code uses the Mod 10 check digit scheme for error
checking. For further information on Mod 10, refer to Appendix C in Volume Two.
