Determining the 'application file ID' of an application...

How do I determine the ‘application file ID’ of an application? I need to know what it is for Acrobat 5.0, but I’d like to learn how to find it. Thanks. 8)

This might work:

set app_ to (choose file with prompt "Select an application")
tell application "Finder" to ¬
	set id_ to creator type of app_
display dialog id_
