Just came to mind - before this goes archive, if you look for a solution to this issue, here is mine:

Code:
for opt in "${@}"
do 	# Only parse for Arguments
	# if variable:'opt' starts with '-'
	[[ "-" == "${opt:0:1}" ]] && \
		case "${opt:1}" in
		"h" | "-help")
			echo "Usage: $FUNCNAME [options] arg1 arg2"
			exit 0
			;;
		"1" | "2" | "3")
			ROWS="${opt/-}"
			shift
			;;
		esac
done

Hope this helps and stay healthy
