Nitpick: COPY /B file.1 + ... + file.n big.rom

The /B tells it to do a binary copy - DOS uses ^Z (Ctrl-Z) as an
end-of-file marker, and gets confused in text mode.

In text mode (COPY), if the file *contains* a ^Z, nothing happens, but if
a file *ends* with a ^Z, the ^Z is dropped. It confused the hell outa me
the first time I tried concatenating ROMs where one file just happened to
end in a ^Z, until I actually looked at what the concatenated file
contained.

In binary mode (COPY /B), this problem never occurs, and a trailing ^Z is
treated correctly, resulting in a correctly-concatenated ROM.

Later,
Doug.
