Logical operators
By patvdv at 26 Feb 2008 - 21:56


Logical operators

Logical operators perform logical operations on their operands. The operator NOT is unary, so it has only one operand. The operands of logical operators can be logical expressions, relational expressions, variables, or constants.

 

The following table illustrates the results of logical expressions:

A B NOT A A AND B A OR B
FALSE FALSE TRUE FALSE FALSE
FALSE TRUE TRUE FALSE TRUE
TRUE FALSE FALSE FALSE TRUE
TRUE TRUE FALSE TRUE TRUE

Variables or expressions of type LONG can be used as boolean. If a long expression results in the value zero, it is evaluated as FALSE. If the result is not equal to zero, it is evaluated as TRUE
