Not Operator
Description
Used to perform logical negation on an expression.
Syntax
result = Not expression
The Not operator syntax has these parts:
Part | Description |
|
result | Required; any numeric variable. |
expression | Required; any expression. |
Remarks
The following table illustrates how result is determined:
If expression is | Then result is |
|
True | False |
False | True |
Null | Null |
In addition, the Not operator inverts the bit values of any variable and sets the corresponding bit in result according to the following table:
If bit in expression is | Then bit in result is |
|
0 | 1 |
1 | 0 |

Example
This example uses the Not operator to perform logical negation on an expression.
Dim A, B, C, D, MyCheck
A = 10: B = 8: C = 6: D = Null ' Initialize variables.
MyCheck = Not(A > B) ' Returns False.
MyCheck = Not(B > A) ' Returns True.
MyCheck = Not(C > D) ' Returns Null.
MyCheck = Not A ' Returns -11 (bitwise comparison).
