Alias and Call Routing Configuration: Alias Macros
7-21
Wildcard Symbols
Macros have two available wildcard symbols:
z ? matches any single character.
z * matches zero or more characters.

Note: Alias names that use wildcards are not really macros. Wildcards are not
processed in alias names that start with ‘=’.
Operators
Operators are used for calculation of mathematical expressions in alias macros.
AI232 evaluates expressions from left to right in order of precedence as shown in
Table 7-10 . To change the order of precedence, a programmer may enclose a portion
of an expression in parentheses ( ) to calculate that portion first.
AI232 evaluates both regular and boolean logic operators. Refer to Table 7-10 for a
list of all available operators in order of precedence.
4+3*2 Specifies an equation that equals 10.
(4+3)*2 Specifies an equation that equals 14.
