Assume the file `word-list' contains the list of words to be changed,
and the files to be processed are `file_1 file_2 ... file_N'.  Then the
following command will do what you want:

	lowercase word-list file_1 file_2 ... file_N

...where `lowercase' is the following shell script.
Can you figure out why I `complicated' the `ex'-script?
--------------------cut here--------------------
#!/bin/sh
# @(#)lowercase 1.0 90/05/04 Maarten Litmaath
# Usage: lowercase word-list [files]
# use `-' for `word-list' if the list is supplied on stdin

script=/tmp/foobar.$$
tmp=/tmp/glork.$$
umask 077
cleanup='rm -f "$script" "$tmp"'
trap 'eval "$cleanup"; exit 2' 1 2 3 15
trap 'eval "$cleanup"; exit' 0

test $# = 0 && {
	set x -
	shift
}
cat "$1" > "$script"

	sed -f "$script" "$i" > "$tmp" && cp "$tmp" "$i"
