This article applies to the following:
The Alias list (Project Properties > Compile tab) allows you to give a set of other module names to a library for the purpose of linking. This will allow you to combine multiple libraries together without breaking backwards compatibility.If there are two libraries, LibraryA.cod, and LibraryB.cod, and they are used by multiple application and there is a code duplication between LibraryA and LibraryB, you can roll LibraryB's functionality into LibraryA. In order to allow this library to seamlessly replace LibraryB, add LibraryB to the Alias list of LibraryA, as depicted by the following image:
To alias multiple libraries, separate them with semicolons. For example, LibraryB;LibraryC;LibraryD
