I think this will work (modified from an rc script of mine):

while (! ~ $#* 0 && ~ $1 -* && ! ~ $1 --) {
	switch ($1) {
	case -a;	destsonly=yes
	case -b;	copies=($copies $2) ; shift
	case -c;	copies=($copies $user)
	case -v;	verbose=yes
	case -*
		echo usage: $0 '[-acv] [-b bcc] [file]...' >[1=2]
		exit usage
	}
	shift
}
# process $*, which now lacks options ...

I think this is the only situation in which I used to wish for `break'
in rc, but it no longer seems worthwhile.
