mmddstr=(`FileNameMon.sh $month`) # will return an array with the month-day strings.
To get the array size, rather than the length of an array element, either ${#mmddstr[*]} or ${#mmddstr[@]} works well. One should notice that ${#mmddstr} shows something different but the max length of all the array elements.
