  $ SORT/STATISTICS PRICE1.DAT,PRICE2.DAT PRICE.LIS

      This SORT command results in the following statistical display:

                   OpenVMS Sort/Merge Statistics

 Records read:         793          Input record length:       80
 Records sorted:       793          Internal length:           80
 Records output:       793          Output record length:      80
 Working set extent:   100          Sort tree size:           412
 Virtual memory:       433          Number of initial runs:     2
 Direct I/O:            22          Maximum merge order:        2
 Buffered I/O:           9          Number of merge passes:     1
 Page faults:         3418          Work file allocation:     114
 Elapsed time: 00:00:05.98          Elapsed CPU:      00:00:03.63

      In the sample statistics display, the Sort data structure
      size is limited by the small working set extent. By doubling
      the working set extent you can almost double the Sort data
      structure size, enabling all the records to fit in memory
      without using work files.
