VBS TUTORIAL: operator-and operator _vbs

And operator

Two expressions are logically "and" operations.

result = expression1 And expression2

Parameters

Result

Any numeric variable.

Expression1

An arbitrary expression.

Expression2

An arbitrary expression.

Description

If and only if all two expressions are true, result is true. If any of the expressions are false, result is false. The following table shows how to determine result:

If expression1 is	and Expression2 is	The result is
True	True	True
True	False	False
True	Null	Null
False	True	False
False	False	False
False	Null	False
Null	True	Null
Null	False	False
Null	Null	Null

The AND operator also performs a bitwise comparison of the identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:

such as the bit in the expression1 is	and the bit in the expression2 is	The result is
0	0	0
0	1	0
1	0	0
1	1	1
