>> Does anyone know how to make a commend to only choose the last 4 numbers out of 8... for example, when we have birthdate of 8 numbers (yyyymmdd) and I only want the last 4 indicating the month and date (mmdd), how can I get it? Then do I use the same commend to extract the last 2 numbers (dd)? What if I only want the last 3rd and 4th number (mm)?
