The old/new files are needed to set the varibles to hold the new number for the next time as this is run via cron. old = ATX060 new = ATX070 ....then, after the script changes the line in the perl script, it needs to pipe (echo/cat) in the new file contents to the old: cat newfile > oldfile ---> which is now ATX070 for oldfile ...then incremement the newfile to become "ATX080" and so on.... Now, got to figure out how to increment number up. It is an invoice prefix number that contains the month # and must modify the perl file that is part of a custom order set of scripts.....
