HI,
I have noted that using for the sake of this example ChangeBlockInsertionV1-1 after CopyRenameBlockV1-3 yield s "* Error : too few arguments **". I believe this is due to the two lisps sharing the same variables which is plausible given they have been written by the same author. I wonder whether there is a way to flush all variables automatically following use of an autolisp or visual lisp.
Thanks for your help.
