Underneath

The problem, and it is a problem, is that I have a set of alphabet tiles 
called names such as

"A.png", "B.png" and "C.png" [trying to be original here]

and they all contain this script:

on mouseDown
    put the short name of me into IMENA
    delete the last char of IMENA
    delete the last char of IMENA
    delete the last char of IMENA
    delete the last char of IMENA
    clone me
    set the name of the last image to IMENA
    set the script of img IMENA to fld "fscrip"
end mouseDown

So field "fscrip" has to contain a UNIVERSAL script that will work with 
every new tile without
any reference to the name of a target over which it is dragged:

I have been trying by having this in fld "fscrip":

on mouseDown
grab me
end mouseDown

on mouseUp
    put the short name of me into IMENA
    if within(img ("%" & IMENA), the mouseLoc) OR within(img ("^" & 
IMENA), the mouseLoc) OR within(img ("#" & IMENA), the mouseLoc) then
          --nix
          else
             move me to 1000,700
          end if
end mouseUp

The main problem being that that script throws a "bluey" if there are 
not 3 targets called,
for example "%A", "^A" and "#A"

Ultimately this is far from satisfactory as there could be anywhere 
between 0 (zero) and about 12 targets.

As the specific targets are unknown for each letter they cannot be 
specified.
