Match Code String (1 - 8)
Field Type Options
Edit Text
0 to 32 characters
Blank
Defines the characters for a specified match code string (1 - 8). The
default is nothing (blank), which means a match code string is not
defined.
You can enter up to 32 characters for each match code string
(including non-printable control characters). Enter the characters as
they will be transmitted to the host. Do not include check digits if
you disabled the Include Check Character parameter for the
selected symbology.
The string accepts the question mark (“?”) as a single character wild
card. A position containing a ? will match any single ASCII
character in the same position of the decoded data.
Note: The Primary and Extended Match Code tables interpret a
question mark differently than do the Host Replacement rules. The
question mark functions as a generic wildcard when used in the
primary match code table, and as a metacharacter in the Host
Message Replacement Rules. (See Chapter 10.)
