is the former the better way to do it then? or are there other alternatives?
If you don't want to use existing option parsers I'd recommend this style: args <- getArgs case args of first:last:z -> ... _ -> show_usage where show_usage = print "expected arguments: first last z" this way you can "die cracefully" if options are passed the program it didn't expect. Marc Weber
