Used to perform a logical conjunction on two expressions.
result = expression1 And expression2
result
Any numeric variable.
expression1
Any expression.
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 following table illustrates how result is determined:
If expression1 is |
And expression2 is |
The result is |
