Eqv Operator
Used to perform a logical equivalence on two expressions.
Syntax
result**=expression1Eqv**expression2
The Eqv operator syntax has these parts:
| Part | Description |
| result | Required; any numeric variable. |
| expression1 | Required; any expression. |
| expression2 | Required; 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 is | And expression2 is | The result is |
| True | True | True |
| True | False | False |
| False | True | False |
| False | False | True |
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 is | And bit in expression2 is | The result is |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
