List to String in ASOC

Converting a list to a string doesn’t work the same within ASOC Xcode.
What needs done to get the correct string back?

I have a table view connected to an array controller. I then get the data and iterate thru each one removing the first two characters, but when I log the result I have returns. Tried delimiters with no success.

 repeat with i in insigniaNumberData
            set my insignia to ((item 3 thru 8 of i) as string)
            log insignia
            end repeat

5

Doing the same in the will finish launching handler I get this result…

 set insigniaNumbers to {"MP112233", "AC223344", "DC334455", "CI445566"}
repeat with i in insigniaNumbers
	set insignia to ((items 3 thru -1 of i) as string)
	log insignia
end repeat

Current result

You’re not dealing with a list, you’re dealing with an array. So you either coerce that to a list first, or use different approach.

You also shouldn’t be using (items x thru y of …) as string – it’s inefficient and relies on the value of text item delimiters. You should use text x thru y of … instead.
