Alias and Call Routing Configuration: Alias Macros

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.

4+3*2 Specifies an equation that equals 10.

(4+3)*2 Specifies an equation that equals 14.

AI232 evaluates both regular and boolean logic operators. Refer to Table 7-10 for a list of all available operators in order of precedence.
