Left on all list items?

I see that when you use Left(return separated list; 10) it gives you 10 of a count of every character in the list. So if you had 10 list items all 20 characters long in the list you just get back 10 characters of the 1st one only. How can you use Left with a list and make it shorten every Item in the list?

One by one, using a recursive custom function (or a looping script).

 

Note that this would be trivial if the values were individual records. Filemaker's understanding and manipulation of return-separated lists is very limited compared to data stored in the fundamental records/fields structure.

To expand on Comment's comment:

 

Why do you need to do this in the first place?

 

It would be helpful if you would present a bigger and more complete picture of what your solution does and how the data is structured.
