Add component to assembly with user input

Hi Everyone,

I'm using NX9 and have been exploring journal recently, also I don't have any programming background and so I hope you'll be able to help me with my question. I manually added a part in my assembly and recorded the journal. However, I want to modify the code in which I can have a user input box asking for specific part number before the execution. Please note that I'm using a TC/NX integrated system. Thank you very much!
