Your analysis of the bug as being in > code.py seems plausible. Yeah. I came across this as I was knocking together a test for something else, and my work-around was to define the inner function as just "pass", and then go back and edit in the nonlocal declaration after adding the assignment outside. The only problem is that it's syntax-checking something that's only half-entered, and is bombing on it - thus stopping you from typing in the bit that would make it valid. Thanks Terry for the extra info on the tracker issue. ChrisA
