Operators
result of this part of the expression is true, becoming the second condition to the AND operator.
Since both portions of the AND statement are true, statement 1 executes.
X = 2
Y = 7
Z = 12
IF ((X = 2) AND ((Y > 4) OR (Z <= 8)))
(* Statement 1 *)

Evaluates two conditions. These conditions must be true for the entire expres-
sion to be true. AND is typically used in IF statements to check for multiple true
conditions.
Example:
IF((X = 1) AND (Y = 2))
{
(* These statements are executed if the
above And statement is true; that is,
if X = 1 is true and Y = 2 is true. *)
}
Use when the opposite of a condition makes the expression true.
Example:
IF (NOT (X = 2))
{
(* If X <> 2, these statements are executed *)
}
Typically used in IF statements to check for a true condition. The logical opera-
tor OR is used to evaluate two conditions. At least one of the conditions must
be true for the entire expression to be true.
Example:
IF ((X = 1) OR (Y = 2))
{
(* These statements are executed if the above
OR statement is true *)
}
Evaluates two conditions. Only one of the conditions can be true for the entire
expression to be true.XOR is typically used in IF statements to check for a sin-
gle true condition.
Example:
IF ((X = 3) XOR (Y = 1))
{
(* These statements are executed if only one of
the above conditions is true *)
}
