SORT-MERGE/XL Programmer's Guide

Getting Statistical Information 

For comparison or other purposes, SORT-MERGE/XL allows you to report
statistical information.  The statistical information provided by
SORT-MERGE/XL includes:

 *  Number of input files (MERGE/XL only)

 *  Number of records sorted (or merged)

 *  Number of intermediate passes (SORT/XL only)

 *  Number of bytes used for the sort work area

 *  Number of comparisons (SORT/XL only)

 *  Amount of CPU time used (in milliseconds)

 *  Elapsed time (in milliseconds)


NOTE  If SORT-MERGE/XL aborts, the values returned in statistics and
      printed out by HPSORTSTAT and HPMERGESTAT are unpredictable.


Syntax for HPSORTSTAT and HPMERGESTAT is:

     HPSORTSTAT (status, statistics);

     HPMERGESTAT (status, statistics);

HPSORTSTAT and HPMERGESTAT print the statistics array to $STDLIST.

An example of using HPSORTSTAT follows:
______________________________________________________________________
|                                                                    |
|     var                                                            |
|       status : INTEGER;                                            |
|       statistics : array [1..6] of INTEGER;                        |
|          :                                                         |
|     HPSORTSTAT (status, statistics);                               |

The intrinsics and parameters required to get statistical information
are:

 *  HPSORTINIT or HPMERGEINIT - statistics parameter must be specified.

 *  HPSORTEND or HPMERGEEND - statistics parameter must be specified.

HPSORTSTAT or HPMERGESTAT must be called after HPSORTEND or HPMERGEEND.
