If the stoppage is intermittent then there is possibly a variance in variable values or properties that you haven't made allowance for.
You have CMDECHO on ... what is displayed on the command line when it stops. ?
You could add different prompt statements at intervals to give you a visual marker of progress through the file .. that is a fairly common bebugging technique.
thanks Kerry,
But there is no error message and all steps follow the questions.
I have put the CMDECHO to see.....but nothin..
also, i have put many alert messages box...if not a string..if variable nil etc...
but all work properly.
the program stop at the end of lisp.....It did not make a _OPEN command again.

I also verified the EXPERT mode....
I have thaw the possibilities in a read-only file....but was not.
a possibilities of a currupt file.....but nope !
