Steven: Thanks very much for taking so much time and effort to answer my question. I will file this writing for future and ongoing reference. BTW: I was able to solve the problem. Essentially a clone of Eval() was being called and probably clobbering the stack frame. It was a tedious process of tracking thru known and likely code dependencies and insert debugging stubs. I've written my own debugging macros using vimscript and from your input I would guess that assert would have just clouded the process. thanks again. -- Tim tim at johnsons-web.com or akwebsoft.com http://www.akwebsoft.com _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
