Syntax

logicalExpression1 or logicalExpression2

Description

Operator; performs a logical OR operation on two or more logical expressions to determine

whether any expression is TRUE.

This is a logical operator with a precedence level of 4.

Examples

This statement indicates in the Message window whether at least one of the expressions 1 < 2 and

1 > 2 is

TRUE:

put (1 < 2) or (1 > 2)

Because the first expression is TRUE, the result is 1, which is the numerical equivalent of TRUE.
