result. Exclusive Or evaluates the result as false and sets a 0 bit in the result. (An
Exclusive Or applies the rule "one or the other, but not both.").

Miscellaneous Operators

The following table lists miscellaneous operators:

The conditional operator (?) takes three operands. Its syntax is as follows: ICM software
evaluates the expression by first examining the logical expression condition and then

Conditional

?

doing the following: If the result is true, then the overall expression evaluates to the value
of the expression true-result. If the result is false, then the overall expression evaluates to
the expression false-result. The following expression determines whether the number of
agents available for skill group S1 is even or odd:

The concatenation operator (&) joins two strings end-to-end. returns the value

Concatenation

&

The sequential or comma operator (,) takes two operands, each of which is an expression.
ICM software evaluates the left expression first and then the right expression. The value

Sequential

,

of the overall expression is the value of the right expression. The first expression typically
affects the valuation of the second.

The shift left (<<) and shift right (>>) operators shift the bits within a value. The following
example shifts the bits in Avail two places to the left. The two right-most positions are

Shift left

<<

filled with zeroes: The following example shifts the bits in Avail two places to the right.
In this case, the positions are filled with sign bits (0 if the original value is positive or
zero; 1 if the original value is negative).

Operator Precedence

The following table shows the order in which operators are evaluated.

Note: The operators with priority 1 are evaluated first, then those with priority 2, and so on.
The order of evaluation within each priority level can also be important. Prefix operators are
evaluated from right-to-left in an expression. Assignment operators are also evaluated from
right-to-left. In all other cases where operators have equal priority, they are evaluated left-to-right.
