I see what you mean. Fixing this sounds like a good idea. Another change along these lines that would help here and in other cases would be if the filein methods automatically posted a warning at the end if the number of Undeclared variable increased (or even decreased?) during the filein. I have more than once filed in some code and forgotten to check Undeclared only to regret it later.
