Using terms from application...

Why these dont work?

ES create subfolders "Macintosh HD:Users:cirno:Desktop:testing:testing2:"
using terms from application "Extra Suites"
	ES create subfolders "Macintosh HD:Users:cirno:Desktop:testing:testing2:"
end using terms from

Is “Extra Suites” an application?
AFAIK it’s a scripting addition

So how this changes things?

To talk to applications you need a tell block or a single tell command.
In contrast scripting additions are accessible directly.

What do you need the using terms from for?
It’s very hard to guess the context of the question :wink:

Extra Suites is a faceless background application that needs to be “told”.

This works:

tell application "Extra Suites" to set Dk to ES dock info

This doesn’t:

using terms from application "Extra Suites"
	set D to ES dock info
end using terms from
