/TAIL[=count]

   Extract records from the end of the file(s).  'count' is the number
   of records to extract; if not present, the default value is 22.

   A negative 'count' value designates the number records at the start
   of the file to omit.  That is, /TAIL=-5 will extract the entire file
   except for the first 5 records.

   Incompatable with /BLOCKS, /RECORDS, and /HEAD.
