I just set up a sub_filter exit on a list here and discovered some syntax pecularities. The exit name is UD-LEXIT EXEC and the name needed to be quoted in the list_exits parm in local sysvars but didn't work if quoted in the exit list header keyword. The header was accepted with exit = 'ud-lexit exec', but the exit wasn't called. Also, LSVPUT didn't work for sending the exit and the file the exit mails out to Listserv--some message to the effect it didn't know where to put them. So I stopped Listserv and copied the files. Is there a better way to do it? /Jim
