It would help us to help you better if you told us, exactly how you are getting input from your user. For example, if the user fills in an HTML form, a possible approach is the MAXLENGTH attribute:

<input type="text" name="irah" maxlength="10 value="">

Otherwise, there are the length and substr functions. Looking at the questions you ask, maybe reading perlfunc and a good introductory book to Perl would be in order?
