1.)  Introduction

     This file describes the  installation  of the  data  plotting
     software  DISLIN  on IBM-PCs  for Windows and Absoft Pro For-
     tran v10 and later. 

     The libraries  in this distribution are created from the DIS-
     LIN C source together with wrapper routines for Fortran.


2.)  Installation of DISLIN

     The DISLIN distributions for Absoft Pro Fortran are distribu-
     ted  in  the  zipped files  dl_11_af.zip  (version 8, 9)  and
     dl_11_a2.zip (version 10.x, 11.x).  An  utility for unpacking
     the DISLIN  files is  available  from the same location where
     you have downloaded DISLIN, or from the DISLIN CD-ROM. 

     To install DISLIN, make the following steps:

  a) Create a temporary directory and copy the files dl_11_a2.zip
     and unzip.exe to it:

     for example:   md  c:\temp
                    cd  c:\temp
                    copy e:\dislin\windows\unzip.exe    *.*
                    copy e:\dislin\windows\dl_11_a2.zip *.*

  b) Extract the DISLIN files with the command:

                    unzip -o dl_11_a2  

  c) Run the setup program with the command

                    setup

     -  Choose OK

     -  Give the Installation Directory where  DISLIN  should be in-
        stalled. The default directory is C:\DISLIN.

  d) Reconfigure the System

     Set the DISLIN environment variable to c:\dislin and include
     c:\dislin\win in your path. If you have installed DISLIN in a
     different directory, you have to use that directory for the 
     environment variables above.

     The environment variables can be set or modified with the Control
     Panel 
    
     (see Control Panel -> System -> Advanced -> Environment
      Variables).

  e) Now you can compile,  link and run the example programs in the
     DISLIN subdirectory examples with the commands

                 DLINK   -a  exa_f77      (for F77)
                 F90LINK -a  exa_f90      (for F90)
     and
                 DLINK   -a  map_f77      (for F77)
                 F90LINK -a  map_f90      (for F90)

     Notes:

      - This DISLIN distribution does not contain a pre-compiled
        'dislin.mod' file for Absoft f90. Please compile the file 
        'dislin.f90' in the DISLIN\af and DISLIN\af\real64 
        directories with the command f90 -c dislin.f90.

      - Beginning with version 10.1 Absoft has changed the default
        options for subroutine and function names. If you are still
        using Absoft Pro Fortran version 10.0, you should compile 
        'dislin.f90' with the command 
        f90 -c -YEXT_NAMES=LCS -YEXT_SFX=_ dislin.f90, and
        if you are not using the statement 'USE DISLIN' in your
        programs, you must also compile them with the options 
        -YEXT_NAMES=LCS and -YEXT_SFX=_.
        The corresponding options for Fortran 77 are -f for lowercase
        procedure names and -B108 for a trailing underscore. 

      - F90LINK and DLINK use by default the DISLIN single precision
        library disaf.lib for linking. A double precision version of
        the library is also included with the name disaf_d.lib.


3.)  Getting DISLIN Support

     The DISLIN distributions can be used freely without any restriction.
     Access to the source code is availabe via a support contract from the
     site www.dislin.de.
