1.)  Introduction

     This file describes the  installation  of the  data  plotting
     software DISLIN on IBM-PCs for Windows and the Portland Group
     compilers pgf77 and pgf90.


2.)  Installation of DISLIN

     The DISLIN version for the Portland Group compilers pgf77 and
     pgf90 is  distributed  in the  zipped  file  dl_11_pg.zip.  A  
     utility for unpacking the DISLIN files is available  from the
     same location where you have downloaded dl_11_pg.zip, or from
     the DISLIN CD-ROM. 

     To install DISLIN, make the following steps:

  a) Create a temporary directory and copy the files dl_11_pg.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_pg.zip *.*

  b) Extract the DISLIN files with the command:

                    unzip -o dl_11_pg  

  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 pgf77)
                 F90LINK -a  exa_f90      (for pgf90)
     and
                 DLINK   -a  map_f77      (for pgf77)
                 F90LINK -a  map_f90      (for pgf90)

     Notes:

      - If your  Portland Group pgf90 version does not recognize the 
        format of the module file  'dislin.mod',  you can re-compile 
        the file 'dislin.f90' in the DISLIN\pgf and DISLIN\pgf\real64
        directories with the command 'pgf90 -c dislin.f90'.

      - The file DISLIN.MOD contains interfaces for all DISLIN 
        routines.  It should be used in all DISLIN Fortran 90 programs
        and subroutines with the USE statement.

      - F90LINK and DLINK use by default the DISLIN single precision
        libraries dispgf.lib and disdll.lib for linking. Double preci-
        sion version of the libraries are also included (dispgf_d.lib
        and disdll_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.
