Run another script from within the code

I know this probably a simple question but I can’t find anything on the Internet about it.

I’m writing scritps in iTunes and I want to run another script from within my applescript code. How can I do this?

I have no experience in this area, but I know it is possible. Here are a few links that may help you out:

Call a handler script

Call a script saved as App

More on script calling.

Good luck, hope this helps.
