Yes, that's the theory. Unfortunately, COMMAND.COM uses a 128-byte internal
line buffer even during batch processing. COMMAND does NOT check for overflow
during %argument% expansion. Trying to get a line longer than 128 bytes will
overwrite some part of COMMAND and (probably) crash your machine. Sorry, no
luck this way.

P.S.: Checked and tried on MSDOS 3.1. Chances are it doesn't work on other
      versions either.
