Has someone tried to add commands to listserv ? Was it easy or not ? Gives it problems when a new version of listserv is installed automatically ? Is there some documentation to start with ? On our MVS was a COBOL program that allows users to search the telephone directory of our university. I have made the same command available on our VM (MVS is a guest and the data are on a shared disk), and now we are looking for possibilities to extend this feature to our whole KULnet network (via listserv or another server). Thanks, -Herman-
