Well, I admit that makes sense. I used “at end of graphics” because that is what I have always seen in applescripts for OG. I thought it was just syntactic sugar for adding a new element to the list. I had no idea that variation was even possible. Are there other things you can plug in in “at X of graphics” ? (Note that “in front of” and “behind” would have been more mnemonic.)

P.S. As for the close front window, that's because this is part of a lengthy series of figures that are saved in separate files; it is just easier to close the window before each one.

Update:
P.P.S.
Thanks, by the way.
