Example: If Match Length is set to 6 in a 10-character symbol, and
Match Start Position is set to 2, only the 2nd through 7th characters
(from left to right) will be compared.
Defines the length of the character string that will be compared with that
of the master symbol when Match Start Position is set to 1 or greater.
When Match Start Position is set to 0, no comparison will occur.

Example: When the Wildcard character is defined as the default asterisk,
defining CR*34 as the master symbol will result in matches for CR134
and CR234, but not CR2345. Entering URGENT** as your master symbol
will result in matches for URGENT, URGENT1, and URGENT12 but not
for URGENT123. This means any wildcards appended to the master
symbol data will result in matches of symbols in variable lengths up to the
master symbol lengths but not over. However, wildcards in the beginning
or center of a symbol (e.g., UR**NT) do not allow for variable symbol lengths.
Wildcard Character allows a user to define a wildcard character as part
of the master symbol.

* (asterisk)
Any ASCII character.
Sequence on No Read is useful when the reader needs to stay in
sequence even if no decode occurs.
When Sequence on No Read is Enabled and Matchcode is set to
Sequential, the reader sequences the master symbol on every match or
No Read. When disabled, it does not sequence on a No Read.
