Bugs fixed:
         Wrong Serial/Number displayed on AIX6.1. Fixed


   Release Notes for Version 6.82 :

Bugs fixed:
         1) Memory allocation improvement. All systems

	 2) Include/Exclude filtering bug. Fixed


   Release Notes for Version 6.81 :

         1) AIX, Solaris, Linux : hang/segmentation fault could occur on low memory condition.  Fixed.

         2) input/output file mismatch with COPY operation. Fixed.


   Release Notes for Version 6.80 :

Bugs fixed:
         1) Error in parsing AND/OR conditions in INCLUDE/EXCLUDE statements. Fixed.

         2) Could not use COMP-3 fields in the include or omit. Fixed.
New features:
        Up to version 6.79, XSM Serial Number used for licence activation was calculated on IBM Hardware Serial
        Number and LPAR Id. Thus it was not possible to move a LPAR running XSM from a system to another.
        Upon clients requests and specialy for clients using IBM POWER Live Partition Mobility (LPM), XSM from
        v6.80 is now only bound to AIX Operating System and no longer to Hardware, making it possible to move 
        a LPAR during XSM jobs.


   Release Notes for Version 6.79 :

Bugs fixed:
         1) SUN SPARC Solaris 5.8/5.10, IBM Power AIX 5.3, 6.1 : Wrong Memory allocation.  Fixed.

           (IBM p510 lcpu=4 mem=7168MB ent=0.30 AIX6.1)


   Release Notes for Version 6.78 :

Bugs fixed:
         1) SUN SPARC Solaris 5.8/5.10 : XSM007E_0174 Cannot open Input file.  Fixed.
         2) IBM Power AIX 5.3, 6.1 : Wrong Memory allocation when low available free memory.  Fixed.


   Release Notes for Version 6.77 :

Bugs fixed:
         1) OUTREC FIELDS format incorrectly parsed.

         2) inputfile read error could occur on +30GB (SPARC Solaris)

         Performance improvement on Multitasking and I/O operations 
         Ex: sort 10 GB (100 millions records x 100 bytes, no sortwork), Intel Core2 E8500, 2GB Ram
            V671 :   total 370 sec.
            V677 :   total 300 sec.
            V671 :   total 850 sec.
            V677 :   total 550 s. 

New features:
        API released.   Included as part of XSM Software licence.
        Delivered as static and dynamic libs + C/C++ header.
        Compatible with all programing languages which are standard Link Edit compliant
        (C, C++, VB, .Net, Pascal,  ...)


   Release Notes for Version 6.71 :

Bugs fixed:
         1) Text records too long and IOERROR IGNORE could cause a crash in sort operation.

         2) Too many long file names in INPFIL statements caused a crash.
            Buffer for input filenames was 4K, too short for +100 long pathnames. 
	    Now use dynamic allocation : no more limit on number of input files.

         3) VFIELDS (all systems) : on large files, following error could randomly occur:
            "XSM063E The file xxxxx/srtw3254.03a is not sorted at record # yyy"

         4) minor correction in INCLUDE/EXCLUDE operation precedence

New features added:
      --skip-head=n     :  will drop the first n records of the first input file
                           Usefull to throw away a header/title

Minor updates :
          1) Linux : no more need to be root to install hxsm 

          2) Any unknown parameter is flagged as an error [instead of ignored],
             and the job is cancelled

          3) if RECFM=V, the record length is automatically increased by 2,
             thus permitting the user to give a LRECL without dealing with
             'carriage-return' and 'line-feed' chars.

          4) Memory, sortworks, threads optimization for huge files (+100GB)

   Release Notes for Version 6.62 :

Bug fixed:

    - OUTREC option
   With this option, one can reformat the final output records with padding and constant fields, 
   and with selected fields from the sorted records.

   Option may be speciped in 3 ways :

   format #1 :  command line option : --outrec=(specs[,specs...])
   format #2 :  Parameter file : OPTION OUTREC=(specs[,specs...])
   format #3 :  Parameter file : OUTREC FIELDS=(specs[,specs...])[,RECFM=...][,LRECL=...]

   where  specs ::= start,length[,type,offset]
           start  = field start in input record      (mandatory, from 1)
           length = field length                     (mandatory, may be < 0 for last field if RECFM T)
           type   = field type                       (optionnal)
           offset = field offset in output record   (optionnal, from 1)

   If  is omitted in 1st spec, they must be omitted in all specs,
       and fields are concatened in output record


       hxsm ... '--outrec=(14,20,1,,..6)'
       OPTION OUTREC=(14,20,1,6,...)
       OUTREC FIELDS=(14,20,1,6,...)

       are equivalent to :

       hxsm ... '--outrec=(14,20,C,1,1,6,C,21,...)'
       OPTION OUTREC=(14,20,C,1,1,6,C,21,...)
       OUTREC FIELDS=(14,20,C,1,1,6,C,21,...)

   Padding and constant fields:

   The output record may include fields that are not in the corresponding input record.
   These fields may be :
          alpha-numeric fields, padded with a letter, a digit, a space, or  any other byte
          zoned-numeric fields, padded with a digit (most of time 0)
          packed-numeric fields, padded with a digit (most of time 0)

   In this case, 'specs' syntax are as follows:

     1)   any_char,length,S,offset   : alpha field  padded with spaces
          OPTION OUTREC=(...,X,10,S,42,...)    # cols 42 to 51 padded with spaces
          '--outrec=(...,X,10,S,42,...)'       # same

     2)   letter,length,C,offset   : alpha field  padded with 'letter'
          OPTION OUTREC=(...,Z,10,C,42,...)    # cols 42 to 51 padded with letter 'Z'

     3)   digit,length,N,offset   : numeric field padded with 'digit'
          OPTION OUTREC=(...,0,10,N,42,...)    # cols 42 to 51 padded with '0'

     4)   value,length,B,offset   : alphanumeric field padded with byte decimal 'value' (0..255)
          OPTION OUTREC=(...,0,8,B,42,...)    # cols 42 to 49 padded with binary zero
          OPTION OUTREC=(...,20,8,B,42,...)    # cols 42 to 49 padded with (ascii) space
          OPTION OUTREC=(...,255,8,B,42,...)    # cols 42 to 49 padded with HIGH-VALUE (255)

     5)   digit,length,P,offset   : packed numeric field value 'digit'
          OPTION OUTREC=(...,0,3,P,42,...)    # cols 42 to 44 = x'00000C' (packed 0)
          OPTION OUTREC=(...,-1,3,P,42,...)   # cols 42 to 44 = x'00001D' (packed -1)

     6)   digit,length,Z,offset   : zoned numeric field value 'digit'
          OPTION OUTREC=(...,0,3,Z,42,...)    # cols 42 to 44 = x'F0F0C0' (zoned ebcdic +0)
                                                                x'30307B' (zoned ascii +0)
          OPTION OUTREC=(...,9,3,Z,42,...)    # cols 42 to 44 = x'F0F0C9' (zoned ebcdic +9)
                                                                x'303043' (zoned ascii +9)
          OPTION OUTREC=(...,-1,3,Z,42,...)   # cols 42 to 44 = x'F0F0D1' (zoned ebcdic -1)
                                                              = x'303071' (zoned ascii -1)

   Release Notes for Version 6.58 :

   Several bugs fixed:

      - sortwork allocation (Solaris 8)
      - dynamic STORAGE allocation (all systems)
      - KEEP_ORDER (all Systems)
      - improved traces for debug mode (All Systems)


   Release Notes for Version 6.56 :

This version is a major enhancement of XSM
'Basic' version 4 limited to 4GB input file size is abandoned.
From version 6, XSM is now released in 'Pro' version without software limitation.

A)  New features added :

  1 - Almost all options can be used in a command line, using GNU style long options 
      (i.e.           --lrecl=250    instead of   -l 250  )

  2 - New field types :

          numeric ('N')   : fixed length numeric fields with a leading floating sign
                            (-ie  +1   -124  ....)
          zoned decimal ('Z' or 'ZD')  : fixed length numeric fields with a trailing sign
          on the last digit ( "PIC S99999 USAGE IS DISPLAY"  ) ...
          Both methods (Microfocus-like and ACU COBOL-like) are supported.

    Note: This is different from 'packed decimal' ('P' or 'PD', COBOL "COMP-3")

  3 - Support of MicroFocus COBOL special variable format (known as "MFCOBOL" or "MFVariable") : RECFM=M

  4 - Support of multiple format for all input files and the output file :
      each input file may have its own record format (F,T,M) and its own record length
      the output file may have its own record format (F,T,M) and its own record length

  5 - Aditionnal parameter for OUTFILE :
           DISP=O   if output file exists, then overwrite (default)
           DISP=A   if output file exists, then append, else create
           DISP=N   if output file exists, then abort job (same as JCL's DD DISP=NEW)

  7 - New 'OUTREC' parameter :  records written to the output file may be rebuilt
      from the input record, all or some fields, with a different order

  8 - Bunch of new options :

         --activation-key=your-activ-key   # if you don't want to 'install' hxsm
         --keep-order                      # if you want a Non-Destructive sort
         --throw-empty-records             # as you can expect ...

B) Bugs fixed:

   1) Option '-q' (new fashion : '--quiet') will cause XSM to exit silently
      with a return code, whatever the cause of the error.

   2) INCLUDE/EXCLUDE expressions containing constant C' '  (a blank) :
      This caused stopping expression analysis.
      This is now fixed

   3) Fixed files : in some cases, XSM was writing the output file with blank records.
      This is now fixed

C) New syntax for options and command line switches :

 | Inside a Parmfile                    | Old switch                |  New switch                              |

    (*) : new in version 6.5x

D) Sort/Merge Keys :

    FIELDS=(start,len,type,A/D,...) or --key=start,len,A/D,type --key=...

    where type may be :

         C  or  CH  :  Bytes, value 0..255 per byte
         I          :  alpha-numeric field, mixed, where case (upper, lower) must be ignored
         B  or  BI  :  same as CH in this version, but to avoid :
                       in future versions, BI may be used for binary values in half-words, words, double-words.
         Z  or  ZD  :  'Zoned' decimal, from COBOL 'PIC S99999... USAGE DISPLAY'
                       set of ascii digits '0'..'9', the last digit holds the sign, and is an ascii char.
         P  or  PD  :  'Packed' decimal, from COBOL 'PIC S99999... USAGE COMP-3'
                       set of BCD pairs of digits, the last pair holds the last digit and the sign.
         N          :  'Numeric' field, fixed length, with leading blanks and a floating (optional) sign '+/-'

E) Microfocus 'variable' files :

    An internal Microfocus 128 bytes header, plus a set af records.
    Each record is prefixed by a 2-bytes length (Big Endian, 3xxx), 
    and is padded to an even number of bytes

    Note : fields are defined from col. 1 = first significant bytes of the record (2-bytes length is dropped)

    Those files are processed with RECFM=M  (max length=4095)

F) Support of mixed files formats and logical records lengths :

     For each input file or for the output file, you can specify its own record format (RECFM),
     and its own logical record length :

        INPFIL pathname,RECFM=F/T/M,LRECL=nnnn       # parmfile
        --infile=pathname,RECFM=F/T/M,LRECL=nnnn     # command line

        OUTFIL pathname,RECFM=F/T/M,LRECL=nnnn       # parmfile
        --outfile=pathname,RECFM=F/T/M,LRECL=nnnn    # command line

     You can also define a default record format and a default logical record length :

        RECORD          RECFM=F/T/M,LRECL=nnnn       # parmfile
        --recfm=F/T/M   --lrecl=nnnn                 # command line

     Rules :

         if RECFM and/or LRECL is specified for a file, then they are taken in account as expected,


         if there is a default RECFM and /or a default LRECL, then they are taken in account as expected,


         default will be RECFM=T,LRECL=250

G) 'OUTREC' parameter :  

        This parameter allows building output records with selected fields in the input record.

        OUTREC FIELDS=(start_in,length,start_out,type[,start_in...])  # parmfile
        --outrec=start_in,length,start_out,type,...                   # command line

        where :

            start_in : offset (from 1) in the input record
            length   : field length, in byte
            start_out: offset (from 1) in the output record
            type     : ignored, compatibility purpose

       examples :

            Building a 30 bytes output record with contiguous fields from cols. 12-14, 1-10, 14-30
             from input record :
               OUTREC FIELDS=(12,3,1,C,1,10,4,C,14,17,14,C)      # parmfile
               --outrec=12,3,1,C,1,10,4,C,14,17,14,C             # command line

            Building a 80 bytes output record with non-contiguous fields from cols. 12-14, 1-10, 14-30 
             from input record :

               OUTREC FIELDS=(12,3,1,C,1,30,4,C,14,17,64,C)      # parmfile
               --outrec=12,3,1,C,1,10,4,C,14,17,14,C             # command line
            Note : 'holes' will be padded with blanks.

H) Non-destructive sort :

         For each set of output records sharing the same sort keys, the original input order will be preserved.

         This is done internally by adding the input record number as the last ('minor') sort key.

              OPTION KEEP_ORDER                                  # parmfile
              --keep-order                                       # command line

         Note : this option is NOT compatible with '--unique-record', or '--unique-key'

K) Activation key  :

       If you don't want to 'install' the hxsm program once for all using the supplied 'hhnsinst',
       you may specify your activation at each run time :

            OPTION KEY=XXXX-XXXX-XXXX-XXXX-K                   # parmfile
            --activation-key=XXXX-XXXX-XXXX-XXXX-K             # command line

       This feature will be usefull when the XSM API will be released (soon ...), to run home-brewed
       sort/merge applications on different workstations.

L) Multitasking ('Multi-threading') :

       This feature is usefull when sorting (not merging nor copying) large files.

       Its purpose is to 'parallelize' the process of reading the input files by chunks,
       then sorting and writing each chunk onto a sortwork file.

       It gives pretty good performances when several sortwork physical drives are available.

       XSM launch one subtask ('thread') per sortwork directory available, when specified.

       If you have only one sortwork directory, or did not specify any (default = current directory),
       XSM will NOT start multitasking.

       You can force multitasking (for your own curiosity satisfaction) by specifying :

              OPTION PROCS=n                                     # parmfile
              --procs=n                                          # command line

       where "n" is the the number of subtasks that XSM will launch (n=2..4 are good numbers)

       When physical drives are managed  by 'SAN-like', 'RAID-2', or 'VG/LV' subsystems, it may work well.

M) Following soon :

      API (Application Programming interface)
      Support of C-Isam Files

    Feedback is welcome (support@hhns.fr)
