is among - problem

I couldn't resist testing it and here's what I came up with.

I created a field "myfield" loaded with test numbers and a Go button with 
this script:

On MouseUp
   put false into found
   put "1,2,3" into search$
   --  sort field "myList"
   repeat with x = the number of lines in field "myList" down to 1
   If char 1 of line x of field "mylist" is among the items of search$ and 
char 2 of line x of field "mylist" is among the items of search$ and char 3 
of line x of field "mylist" is among the items of search$ then
       If found then
         delete line x of field "myList"
         beep
       else
         put true into found
       end if
     end if
   end repeat

end MouseUp


Points to note:

If you don't care which matching item you keep, then you don't need to sort 
the list.

If you want to keep the lowest (value) one, sort descending, if you want to 
keep the highest one, sort ascending as the search has to start at the last 
item to stop the integrity of the search being destroyed by deletions.
