Re: Help - CPF511D error

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hate to say it, but... this sure sounds like a problem where memory is 
being corrupted.  This would imply a mismatched parameter somewhere 
that's causing memory that doesn't belong to you to get stomped on.

Unfortunately, this could be a bug that's years old.  Even decades old, 
and everyone may have thought it was perfectly okay, because it didn't 
produce an error -- but you were just "lucky"  (or perhaps "unlucky" 
depending on your point of view.)

But other than memory corruption, I can't think of anything that would 
mess up a chain to a file.
