/ERROR_LOG

   You must specify /ERROR_LOG/ELV to access the Error Log Viewer 
   (ELV). This utility is used with error logs written on systems 
   running OpenVMS Version 7.3 and later.

   /ERROR_LOG (without /ELV) invokes the Error Log Report Formatter 
   (ERF), a utility that is no longer supported, but which may be 
   useful for error logs written on systems running OpenVMS versions 
   older than Version 7.2. (It is available only on Alpha and VAX 
   systems.) For documentation about ERF, refer to the Freeware 
   website:

            http://h71000.www7.hp.com/openvms/freeware/

   Before using ERF, you must convert error log files using ELV or the
   Binary Error Log Translation utility, which is part of DECevent.
   DECevent is no longer supported, but those who need it can download 
   the software and related documentation from the Freeware website:
