Professional Edition. What Command or how to.

[SoullaWorks]

If my Clipboard contains a word like a name, which was copied using Ctrl+C and then if the same word or name again appears by way of again Ctrl+C and copied in the Clipboard. How can I tell the Macro Professional Edition to End/Stop/Finish its original task?
Meaning, I want the Macro to recognise that the word/name has just been identified a second time and now only at this point it recognised the same Word/Name to End/Stop/Finish the Macro from continuing any further. Many thanks Soulla.
