Alias and Call Routing Configuration: Alias Macros

Operators

Operators are used for calculation of mathematical expressions in alias macros. AI296 evaluates expressions from left to right in order of precedence as shown in Table 8-19. 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.

AI296 evaluates both regular and boolean logic operators. Refer to Table 8-19 for a list of all available operators in order of precedence.

Operator Description

#Specifies a comment at the ends the alias macro expression.

*Specifies a multiplication operation.

/Specifies a division operation.

%Specifies the remainder of a division operation.

+Specifies an addition operation.

-Specifies a subtraction operation.

Expressions that use the following operators return “0” for a false condition and “-1” for true condition:

<<Specifies a less than evaluation.

<<= Specifies a less than or equal to evaluation.

=Specifies an equal to evaluation.

>Specifies a greater than evaluation.

>=	Specifies a greater than or equal to evaluation.
<<>	Specifies a not equal to evaluation.

&Specifies a boolean logical AND evaluation. This requires that two conditions are true before continuing with the evaluation.

^Specifies a boolean logical exclusive OR evaluation. This requires that one condition or another (not both) is true before continuing with the evaluation.

Specifies a boolean logical OR evaluation. This requires that one

condition or both conditions are true before continuing with the

evaluation.
