Used to perform a logical equivalence on two expressions.
Syntax
result = expression1 Eqv expression2
Arguments
- result
- any numeric variable.
- expression1
- Any expression.
- expression2
- 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
