Overview of the match file
MatchRules define the variables for the address items found in
the reference street file attribute table. MatchRules use VAR
commands to specify variable names, field position, field length,
and missing value codes. You need a .mat file extension to specify
match rules—for example, us_addr1.mat.
The VAR variable names can’t contain more than 16 characters,
and the first character in the name must be a letter of the alphabet.
In addition, names are not case-sensitive, spaces aren’t allowed,
but underscores are permitted.
