Library /sys$common/syshlp/latcp$help.hlb SHOW, SERVICE, Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 service-name

    Specifies the name of the service for which information will be
    displayed. If you do not specify a service name, LATCP displays
    information about all services known to the node.

    You can also specify any valid wildcard for this parameter. For
    example, the SHOW SERVICE LAT_* command displays the status and
    characteristics of all services that begin with the LAT_ prefix.
