NOTE: VGL automatically checks ratio data for validity only within the
allowable hexadecimal range. VGL does not verify that ratio data
creates acceptable bar/space element relationships for bar code
readability. When designing unique ratio data, carefully plot bar/
space ratios to conform to readable bar codes.

EAN 13 Examples
The following command generated the horizontal default ratio EAN 13 bar
code below. In the command sequence, graphics mode data is italicized , and
bar code data is boldface. See Chapter 2 for a detailed description of
alphanumeric commands.
^PY^-^M10,10,000^KF^BYT123456123456^G^KF^-^PN^-
^PY^- enabled the graphics command sequence.
^M introduced the standard alphanumeric command.
The character height selected was 1.0 inches and character width was
selected at 1.0 inches.
A 0.0 justification value plus 0 additional dots was selected for data
placement.
^KF activated Dark Print.

123456123456 is the 12-digit bar code data.
The bar code data. EAN 13 bar codes encode
exactly 12 digits. The first character input is
interpreted as the number system character. (A bar
code character is not produced for the number
system character.) The next six characters are the
left side (the upper side on vertically oriented
symbols). The final five characters are the right side
(or the lower side on vertically oriented symbols). A
thirteenth character is an automatic check digit
which is computed and printed in the last character
position in the right data field. If the 2- or 5-digit
add-on data field is used, include this data at the
end of the data field. The characters available for
the data field are 0 through 9 (hex 30 through 39).
Terminates the bar code command. Enter the
SFCC for your VGL configuration immediately
followed by any valid command character or G, the
universal sequence terminator.
