''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 (Basic) ==

<pre>
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
</pre>

== Example (JavaScript) ==
<pre>
// Not Example
/* Not does logical negation & bitwise inversion */

var Test1, Test2, Test3, x, y;
x = 3;
y = 8;
Test1 = (!x > 0)
Test2 = (!y > 10)
Test3 = !x
NSB.Print "Logical:"
NSB.Print "  Not(x > 0) = " & Test1
NSB.Print "  Not(y > 10) = " & Test2
</pre>

== Output ==

<pre>
Logical:
  NOT(x > 0) = False
  NOT(y > 10) = True
</pre>
