   Version 3.9-D of MXD software for UNIX systems.
   ( VMS, UNIX(HPUX,Linux,Dec_Unix,SGI) and Windows NT systems )


  The MXD ALias are defined in the mxd_setup file :

     For VMS:                MXD_SETUP.COM,
     For Windows NT          MXD_SETUP.BAT,
     For UNIX                mxd_setup.csh        ( csh schell )
                             mxd_setup.bash       ( bash schell ).

  Use of MXD V3.9-D :
  -------------------
                              
  To use MXD on UNIX system you must include in your user profile or
  execute the next following command (can be also in a common profile file):

  if the mxdkit is located in /usr/local/mxdkit directory :

     # source /usr/local/mxdkit/mxd_setup.sh         for HPUX/DEC_UNIX,
     # source /usr/local/mxdkit/mxd_setup.bash       for LINUX.
     $ @MXDLIB:MXD_SETUP                             for VMS.
     C:\xxxxxxx>MXD_SETUP                            for Windows NT/95.


  Examine the mxdguide.doc file for any examples and specifications.

  the main change from the manual are the system call commands.

  You must call the main "mxd" task in a public directory,
  the commands are :

     mxd_cmp <cr>
   or
     mxd <cr>  to enter the terminal mode (as for previous versions).


     mxd_cmp "" <source_file> [<listing_file>] <cr>
   or
     mxd <source_file> [<listing_file>] <cr>
      Is the UNIX equivalent of VMS command ( in the manual )
        mxd <source_file> [<listing_device>] <cr>
        where source_file is your mxd source file
        exemple: "mxd "" mxdlib:absorb<cr>" (in the manual).

        if the listing file is not specified, the listing on TT: is assumed
        and the listing flag is clear (can be set with PRAGMA L+; statement).

     mxd_cmp lsq <source_file> [<listing_file>] [<save_file>] <cr>
     or
     mls <source_file> [<listing_file>] [<save_file>] <cr>
      Is the UNIX equivalent of VMS command ( in the manual )
        mls <source_file> [<listing_device>] [<save_device>] <cr>

  The new form
     mxd_cmp dialog lsq <source_file> [<listing_file>] [<save_file>] <cr>
   or
     mlsc <source_file> [<listing_file>] [<save_file>] <cr>
       Is a mls variant to change without any file edition the number
       of cycle(s) or the listing mode ("OPTION(SHORLST) = YES/NO").
       it is self documented.

  With old MXD versions the listing name was always mxd.lis and mxdlsq.lis
  with this new version the listing name has as specified, with the preffix
  "lsq_" for the least squares file, the default file type is always ".lis".

  With the old MXD version the previous value of variables (from the last MXD
  run) was specified by an include statement that cab be using the logical
  device IN:. For this UNIX version, you can use same mod by using the setenv
  statement to change the in definition as this :

  csh/tcsh shell:

      setenv in ./           (for sy: in VMS system - see the manual),
      setenv in nl           (for nl: in VMS system - see the manual).

  bash shell (for Linux):

      export in="./"         (for sy: in VMS system - see the manual),
      export in="nl"         (for nl: in VMS system - see the manual).


  with this method you must not specify the <save_file> mls (or mlsc)
  parameter.
  If we want use the <save_file> parameter you must suppress any
  "include 'IN:... " statement because the appropriate include is
  automaticaly performed by MXD with the specified parameter value.
  the default extension is ".sav".

                               Good luke with MXD V3.9-D.
