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
// 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);
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
