symbol as in CR*** will result in matches for variable symbol lengths such
as CR1, CR23, CR358, etc. provided that the number of wild card characters
matches or exceeds the number of characters present.
Definition: Wild Card Character allows a user to define a wild card character as part
of the master symbol.
