1.)  Introduction

     This file describes the  installation  of the  data  plotting
     software DISLIN on IBM-PCs  for  the operating system Windows
     9x/NT/2000/XP and the Lahey Fortran 95 compiler LF95.

 
2.)  Installation of DISLIN

     The DISLIN version for the Lahey Fortran 95 compiler  LF95 is
     distributed in the zipped file  dl_81_hf.zip.  An utility for
     unpacking the DISLIN files is available from the same locati-
     on where you have downloaded dl_81_hf.zip, or from the DISLIN
     CD-ROM. 

     To install DISLIN, make the following steps:

  a) Create a temporary directory and copy the files dl_81_hf.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_81_hf.zip *.*

  b) Extract the DISLIN files with the command:

                    unzip -o dl_81_gf    

  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

     Add the DISLIN\WIN directory to the PATH environment in the
     file AUTOEXEC.BAT

     for example:  PATH C:\BIN;C:\LF9035\BIN;C:\DISLIN\WIN

     Add the DISLIN environment variable DISLIN to the autoexec.bat
     file:

     for example:  SET DISLIN=c:\dislin   

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

                    F90LINK  -a exa_f90         
                    F90LINK  -a map_f90      

     Notes:

      - The file DISLIN.MOD contains interfaces for all DISLIN 
        routines.  It must be used in DISLIN Fortran 90 programs
        and subroutines with the USE statement.
        You can use the -MOD switch of the LF95 compiler for com-
        piling programs (see F90LINK).

      - F90LINK uses the DISLIN libraries DISLF95.LIB and DISDLL.LIB.


3.) Getting a DISLIN License

   You can install and check DISLIN for 10 days.  Once this date passes,
   DISLIN must be licensed. See the file 'DISLIN.INF' for licenses and 
   prices. 

   To get a license number, you have to run the program  'license'
   in the DISLIN\win directory:

   license

   The program will create the file 'license.lis'. Send it via E-mail
   to
                   michels@linmpi.mpg.de

   to receive a valid license number. After that, you will be contacted
   by  Garching Innovation  that manages the payment of DISLIN licenses
   (see the file 'DISLIN.INF').
