	switch ("$flag")
		case '-[?]':
			<cmds>
			breaksw
		case '-a':
			<othercmds>
			...
	endsw

This is the only correct entry so far.  Other entries matched -a as well as -?.
One entry had the gall to have the csh invoke a Bourne shell script (is there

I'd still be interested in any other approaches that work.

But imagine that!  Using brackets for quotes!  Who would have ever thought that
the C-shell, with its infinitely helpful programmer-oriented features, has this
level of protection against matching metacharacters!	:-)	:*S
