The Boolean operator Is Not Equal compares two operands and returns True (-1) if the values are not the same, or returns FALSE (0), otherwise. Is Not Equal can be used in both variable and constant expressions. Example:
| Code Block |
|---|
X := Y <> Z |
The above example compares the value of Y with the value of Z and sets X to either: TRUE (-1) if Y is not the same value as Z, or FALSE (0) if Y is the same value as Z.
