Not sure what you dislike about batch log files ...

SUBMIT

   /LOG_FILE

         /LOG_FILE[=filespec]
         /NOLOG_FILE

      Names the log file. The asterisk (*)  and the percent sign (%)
      wildcard characters are not allowed in the file specification.

      When you use the /LOG_FILE qualifier, the system writes the batch
      job's output to the file you specify. If you use the /NOLOG_FILE
      qualifier, no log file is created. By default, a log file is
      created, is written to the directory defined by the logical name
      SYS$LOGIN in the UAF, and is given the batch job's name as its
      file name with a file type of LOG. By default, a log file also is
      given the batch job's name as its file name with a file type of
      LOG.

Seems to cover a lot.
