VBS TUTORIAL: operator-or operator _vbs

Or operator

Make a logical or an operation of two expressions.

result = expression1 Or expression2

Parameters

Result

Any numeric variable.

Expression1

An arbitrary expression.

Expression2

An arbitrary expression.

Description

If at least one of the two expressions is true, result is true. The following table shows how to determine result:

If expression1 is	expression2 for	The result is
True	True	True
True	False	True
True	Null	True
False	True	True
False	False	False
False	Null	Null
Null	True	True
Null	False	Null
Null	Null	Null

The or operator also performs a bitwise comparison of bits in the same position in two numeric expressions, and sets the corresponding bit in result according to the following table:

if The bit in the expression1 is the	expression2 where the bit is
0	0	0
0	1	1
1	0	1
1
