Used to perform a logical equivalence on two expressions. Syntaxresult=expression1Eqvexpression2 The Eqv operator syntax has these parts:

PartDescription
resultRequired; any numeric variable.
expression1Required; any expression.
expression2Required; any expression.

Remarks If either expression is Null, result is also Null. When neither expression is Null, result is determined according to the following table:

If expression1 isAnd expression2 isThe result is
TrueTrueTrue
TrueFalseFalse
FalseTrueFalse
FalseFalseTrue

The Eqv operator 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 isAnd bit in expression2 isThe result is
001
010
100
111

## Example

This example uses the Eqv operator to perform logical equivalence on two expressions.

``````Dim A, B, C, D, MyCheck
A = 10: B = 8: C = 6: D = Null    ' Initialize variables.
MyCheck = A > B Eqv B > C    ' Returns True.
MyCheck = B > A Eqv B > C    ' Returns False.
MyCheck = A > B Eqv B > D    ' Returns Null.
MyCheck = A Eqv B    ' Returns -3 (bitwise comparison).
``````
