result = NOT expression
Description
Not returns the logical negation of an expression. The required argument, expression, is any valid expression. result is TRUE if expression evaluates to FALSE, FALSE if expression evaluates to TRUE, result is NULL otherwise.
Example
Rem Not Example 'Not does logical negation & bitwise inversion Dim Test1, Test2, Test3, x, y x = 3 y = 8 Test1 = Not(x > 0) Test2 = Not(y > 10) Test3 = Not x Print "Logical:" Print " NOT(x > 0) = " & Test1 Print " NOT(y > 10) = " & Test2
Output
Logical: NOT(x > 0) = False NOT(y > 10) = True
