Codabar bar codes require an eight-digit ratio. The
ratios are interpreted from left to right, measuring
the size of each bar or space in dot width. The first
four digits are interpreted as follows: narrow bar :
narrow space : wide bar : wide space . The sixth
digit specifies the number of dots for the
intercharacter spacing. The fifth, seventh and
eighth digits are not used; any data in these
positions is ignored. For example, if the Codabar
ratio data was 24681211, it would be translated as
follows:
data The bar code data. Codabar encodes from 1
through 40 characters from the Codabar Character
Set shown in Table 26. Characters A, B, C, and D
are strictly start/stop codes.
(cc)G 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.
