Sorry for the confusion.
What I was wondering is if AutoCAD does the save all and close all commands. Does that mean it has a way around LISP functions losing focus and ceasing evaluations, if so could that be piggy backed to do other things like scmallory ask.
I can think of a few times I would have liked to run the same routine on all opened dwg's. Now I just run them in each tab and be done with it. (An easy example I did just last week was when my title block insert. (Sheet name, number drafter and EOR.) added a disclaimer. Then they wanted the disclaimer to move. Then they wanted the disclaimer to say something different.) I just did a
(command "insert" "Title block insert=.\\..\\..\\Title block insert" "0,0" "1" "1" "0")
(command "erase" "l" "")
drag and drop in each dwg to redefine it.
That was 96 projects 4 dwg (Sheets) each. 3 separate times.
But if I had a technique I could repeat. I'd be able to do this with a lot of things.
