The LISTSERV log is not a regular disk file maintained by LISTSERV but a system file where VM logs all activity on the LISTSERV virtual console, including error messages from the system, from other processes on the system such as security managers, and so on. It is important to have this level of logging because this is the information you want, in practice, when there is a problem with LISTSERV. The disposition of this file is a matter or local policy, controlled by an "installation exit" (a short program LISTSERV calls to create or close that file and that each site is free to customize). All this to tell you that the only thing LISTSERV can do under the present setup is close this file and start a new one. It can't be searched in the way you would like. Eric
