for csh users, yes. for ksh users, no. in ksh you're allowed to use the form:

	if [ expr ]; then <command>; else <other command>; fi

unfortunately, it doesn't work that way for csh. believe me, i've tried
lots-o-different combinations of ;'s but it comes back and says "else: endif
not found". apparently csh requires that the endif be on it's own line.


have a day, eh.
