I am using a menu line with the following: /appl/fp/rclerk msx -s7 -RO I get the following error: *** A System Error Has Occurred *** /appl/filepro/msx.atty/index.A: Bad file number In auto processing I am looking up the file msx.atty. If I remove the -RO everything works fine. What am I doing wrong? Dennis Malen
