n
– Is encoded as FLG(n), and is interpreted as signaling Extended Channel
Interpretation. When the value of n is from 1 to 6, it signals that the following n
digits comprise an extended channel identifier for use with ECI compliant bar code
scanners. An erroneous bar code symbol may result from failing to follow n
with n digits. Any 0 following n and not within the n digits will be
encoded as FLG(0). In the context of a FLG(n), any backslash ‘\’ (92
10
) will be
interpreted by the scanner as two backslashes ‘\\’.
Example 1: The variable length example encodes “AZTEC” with no ECI input, and 23% error
correction, and prints the bar code. A line of text is also printed.

Example 2: The specified length example includes a byte count field for all bytes that follow until the
end of the bar code data. The byte count is 17. The symbology encodes
“AZTECbarcode”, and prints the bar code. Notice that a does not terminate
the bar code format record. A line of text is also printed.
