Add-On  (Definition)

A program utility that enhances a primary program.  In RC-WinTrans, a software component that extends the application's functionality.

Technically, an RC-WinTrans Add-On is a VBA macros file (file extension = .macro) that has at least one procedure implemented that is to be executed.  The functionality is coded using Microsoft Visual Basic for Applications (VBA) and can do virtually anything a user (third-party manufacturer or needs it to do in order to extend RC-WinTrans' capabilities.

An add-on usually adds at least one menu item to RC-WinTrans' Add-On menu.  The menu command(s) is/are used to start whatever function the add-on provides.
