Overview

The compareLT is the comparison function that can be used with this Data Type. The resulting value is a Boolean value of true or false.

ObjectRepository

The compareLT is the comparison function that can be used with this Data Type. The resulting value is a Boolean value of true or false. The Object Repository files and NOT the file names are compared.

Void

The compareLT is the comparison functions that can be used with native data types and Heap objects. The resulting value is a Boolean value of true or false. The #void constant will always be less than any other value.

Usage

Use the compareLT function when you wish to compare two objects of the same Data Type and determine if the first object is lesser than the second object and you wish the result to be expressed as a Boolean value (true or false). The alternative comparison function,compare, only determines if two objects are equal, less than or greater than.
