When I start an APL session (5.2 or 6.0), Œchdir reports the current directory in lower-case on my Win2K system. It doesn't report it in uppercase until I change drives. Attached file shows example.
Not a major problem, but I have several programs that check for the current drive using Œchdir and expect to see uppercase -- I'll change them to deal with this. Just a surprise to see it.
