The Boolean operator Is Less Than compares two operands and returns TRUE (-1) if the first value is less than the second value, or returns FALSE (0), otherwise. Is Less Than 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 less than the value of Z, or FALSE (0) if Y is equal to or greater than the value of Z.
