Labels only merge with database files, so having an automerge is not practical. An auto merge activates every 60 seconds and it would merge the same information in the database file. In most cases, you only want to merge after the database file has been updated with the new information. The best way to automate this is to call your application program’s MGRLBL command. From there, you can control when this job is done or create a scheduled job if you know when the file is updated ahead of time.
