1.)  Introduction

     This file describes the  installation  of the  data  plotting
     software DISLIN on IBM-PCs  for Windows and the Lahey Fortran
     90 compilers LF90 and ELF90.
 

2.)  Installation of DISLIN

     The  DISLIN version for the Lahey compilers LF90 and ELF90 is
     distributed in the zipped  file  dl_11_lf.zip.  A utility for
     unpacking the DISLIN files is available from the same locati-
     on where you have downloaded dl_11_lf.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_lf.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_lf.zip *.*

  b) Extract the DISLIN files with the command:

                    unzip -o DL_11_LF   

  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

                    F90LINK  -a exa_f90 
                    F90LINK  -a map_f90

     Notes:

      - The file DISLIN.MOD contains interfaces for all DISLIN 
        routines.  It should be used in DISLIN Fortran 90 programs
        and subroutines with the USE statement.
        You can use the -MOD switch of the LF90 compiler for com-
        piling programs (see F90LINK).

      - F90LINK links by default with the DISLIN single precision 
        libraries DISLF90.LIB and DISDLL.LIB, but there are also the 
        double precision libraries DISLF90_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.
