Conditional patterns

When standardizing addresses, some addresses require that conditions be attached to pattern matching. Providing conditional values in patterns allows correct processing of problem cases.

• Simple conditional values
  A simple condition is expressed by the usual pattern operand followed by an equal sign and a value.
• Series of conditional values
  
• Tables of conditional values
  You can specify a large number of conditional values by creating a table of values file.
• Conditional expressions
  The conditional expression is enclosed in brackets immediately following the pattern operand.
• Using arithmetic expressions
  You can include arithmetic expressions as the left operand of a conditional expression.
• Combining conditional expressions
  You can combine conditional expressions by using logical operators.
