Description

   The /LOG qualifier outputs these informational messages to the
   current SYS$OUTPUT device:

   o  For each file processed, the name of the file and the number
      of records selected and rejected from that file

   o  If you use the /SORT qualifier, the total number of records
      merged in the sort (this is the total number of records
      selected from all the files that were processed)

   o  If you process more than one file, the total number of files
      that were processed, and the total number of records selected
      and rejected
