1.)  Introduction

     DISLIN is a  high-level and  easy to use graphics library for
     displaying data as curves, bar graphs, pie charts, 3-D colour
     plots, surfaces, contours and maps. The software is available
     for several C, Fortran 77 and Fortran 90 compilers.

     This file describes the installation of DISLIN for Free Pascal
     and Windows.


2.)  Installation of DISLIN for Free Pascal

     The Windows version of DISLIN for Free Pascal is distributed
     as a  .zip file created with the file packaging utility ZIP
     (version 1.9).
     The .zip file has the file name DL_nn_FP.ZIP where  nn is the
     current version number of DISLIN.

     To install DISLIN for Free Pascal, make the following steps:

  a) Create a temporary directory and copy the files dl_11_fp.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_fb.zip *.*

  b) Extract the zipped files with the command:

                    unzip -o dl_11_fp.zip 

  c) Run the SETUP program with the command

                    setup

     -  Choose OK

     -  Give the Installation Directory where DISLIN for Free Pascal
        should be installed. The default directory is C:\DISLIN.


  d) Reconfigure the System

     Set the DISLIN environment variable to c:\dislin and include the
     directory 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 test the DISLIN examples in the subdirectory 
     fpc of the DISLIN installation directory with
     the commands:

                   fpc  dislin.pas    for compiling the Dislin interface

     After that you can compile, link and execute the DISLIN examples:

                   fpc  curve.pas
                   curve         

                   fpc  surface.pas
                   surface

                   ...         

     Note:  If you want to compile and link a Pascal code with DISLIN
            in a different directory, you can use the following command:

                   fpc -Fuc:\dislin\fpc  curve.pas


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.
