And Operator

Updated: March 2009

Performs a logical conjunction on two expressions.

Copy 
result = expression1 And expression2

result

Any numeric variable.

expression1

expression2

Any expression.

If, and only if, both expressions evaluate to True, result is True. If either expression evaluates to False, result is False. The logical operation is not short-circuited. All expressions are evaluated.

The following table illustrates how result is determined:
