In the past few lessons we have been introducing you to the many tools used within the programming environment. In this lesson, we are going to discuss a tool called Cross Reference. Cross reference is a very useful function that works to find areas within a program that use a certain object or DB address. For instance, if you need to find where a particular timer was used within your logic, you can use the cross reference tool to locate where it was used and what it was used for. Get started with this lesson and we’ll demonstrate how to use this beneficial tool.
