/LOG=file-specification
    /NOLOG

    Specifies the log file that the proxy manager should use to log
    errors. The proxy manager uses this file to record each request
    for a proxy server. The default is /NOLOG. If the /VERBOSE
    qualifier is specified, the default is /LOG. If /LOG is specified
    without a value, the output is sent to SYS$ERROR by default.

    If an incomplete specification is entered, the following
    directory specification is used to complete the command:

    SYS$SYSDEVICE:[]DECW$XPROXYMANAGER.LOG
