Or Operator

Description

Used to perform a logical disjunction on two expressions.

Syntax

result = expression1 Or expression2

The Or operator syntax has these parts:

Part	Description

result	Required; any numeric variable.
expression1	Required; any expression.
expression2	Required; any expression.

Remarks

If either or both expressions evaluate to True, result is True. The following table illustrates how result is determined:

If expression1 is	And expression2 is	Then result is

True	True	True
True	False	True
True	Null	True
False	True	True
False	False	False

(continued)

False	Null	Null
Null	True	True
Null	False	Null
Null	Null	Null

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

If bit in expression1 is		And bit in expression2 is		Then result is

0	0		0
0		1		1
1		0		1
1		1		1

Example

This example uses the Or operator to perform logical disjunction on two expressions.

Dim A, B, C, D, MyCheck
A = 10: B = 8: C = 6: D = Null    ' Initialize variables.
MyCheck = A > B Or B > C                ' Returns True.
MyCheck = B > A Or B > C                ' Returns True.
MyCheck = A > B Or B > D                ' Returns True.
MyCheck = B > D Or B > A                ' Returns Null.
MyCheck = A Or B                        ' Returns 10 (bitwise comparison).
