Good Day Monks, Here is the problem that I am facing: Users are prompted to intput their account numbers which should be a 9 digits, though account numbers are being entered with less than 9 digits. By design I have the ability to "re-format" the entered account number with a single regular expression. With this stated, is there a way in a single regular expression to check the incoming account number for length (in my case 9 digits) and if it is less than that number (e.g., 9 digits) "pad" the beginning with zeros??? Any input will be appreciated!!! THANKS!!!
