Logical Operations
Logical operations are operations that:
- Operates on one Boolean operand or two Boolean operands.
- Produces a Boolean amount by applying the analytic operation defined by the operator.
There are 4 analytic operations accurate in VB:
- Logical add (Add): Consistent (True) if both operands are (True).
- Logical or (Or): Consistent (True) if one of the operands is (True).
- Logical not (Not): Consistent (True) if the operand is (False).
- Logical xor (Xor): Consistent (True) if one and alone one operand is (True).
To appearance you how analytic operations work, I wrote the afterward script, logical_operation.html:
<html>
<body>
<!-- logical_operation.html

<pre>
<script language="vbscript">
document.writeln(True And True)
document.writeln(True Or True)
document.writeln(Not True)
document.writeln(True Xor True)
</script>
</pre>
</body>
</html>
Here is the output:
True
True
False
False
No surprises in the output.
Conclusions
- VB supports 6 numeric comparisons.
- VB supports 4 analytic operations.
