Thanks for your reply, Chris. I am using bash, so the 3rd comment is
applicable. Can you elucidate some more (or point to a reference) for
the fourth comment? I haven't used any of them earlier.

Using that method, each word of the file is placed into one of the
positional parameters, $1, $2, ..., ${10}, ${11}, etc., instead of
into a shell array (which most shells do not support, and is not
part of the POSIX standard).
