I have a lisp file the inserts lot numbers in ascending order. My problem is that this lisp is not applicable in numbering sublots, because for sublots, lot numbering will be alphabetical. For example, A mother lot has a lot number of 234 and is divided into two lots. The first lot number would be "234-A" and the second would be "234-B". Can someone help me with this? Just a newbie in lisp programming. Thanks in advance!
