1.1 INTRODUCTION
----------------

This version of the tutorial on Fortran 90 can be used on
UNIX, Windows 3.1, Windows 95, and Apple Macintosh. It has
only relative links for all files which are direct part of
the tutorial, and uses absolute links only for external
Web-pages.

The reason is that it should be possible to use the book
without any telephone or network connection.

1.2 Web-readers at local use
----------------------------

The Web-readers discussed below all have the property that they
can be used locally (stand alone), if Winsocket has been installed.
An alternative is to instal a "dummy" version of Winsocket,
which does nothing. With the next version of Mosaic a "null" Winsocket
will be provided.

When I wish to use the system locally I just disconnect
the electric power to my external modem. If I am already
running Web on the net, I close the connection with closing
the supervising program, usually trumpet.

Files in HTML on PC using MS-DOS are supposed to end with .htm, but
most Web-browsers also permit call of files using the usual
UNIX-extension .html. The addresses have therefore not been changed
from the previous UNIX version in this respect.

1.2a NCSA Mosaic 2.0 for Microsoft Windows 3.1
----------------------------------------------

This Web-reader had in a previous version the property
that it could be used locally (stand alone), even if no
Winsocket had been installed, and was therefore very suitable.

The system has a few differences compared with on a UNIX-system:

a) It is more critical with respect to national characters
given with for example ä for ä. The semicolon
is now compulsory. This is of course no major problem with
this English version.

b) I have not found any satisfactory solution on how to write
a typewriter or teletype or Courier font for the Fortran-words
in the text. This is further discussed in the document
pc_e.html.

1.2b NCSA Mosaic 2.1 for Microsoft Windows 3.1
----------------------------------------------

In addition to the problems discussed above a completely new and rather
serious problem appears with this revision. When I start Mosaic for local
use, and do not have the modem turned on, the Window system gives the
following message: "SYSTEM ERROR, CAN NOT WRITE ON UNIT AUX" and it
gives the two alternatives "ABORT" and "TRY AGAIN". If I click on
"ABORT" the Mosaic system starts correctly!

The reason for this problem is probably that the revised Mosaic tests
for World Wide connection, before starting.

With the modem turned on, the revised Mosaic works well.

A work-around is available. Add the following two lines to the
windows\system.ini file:

[DEBUG]
OUTPUTTO=NUL

An additional problem is that the system crashes (has to be rebooted)
if you, while without a network connection, click on an external link.

All these problems also apply to NCSA Mosaic 2.1.1. The problem with having
to reboot after an attempt to connect to an external link in local mode has
however been solved. If you wait for a while you will get the error message
"HTAccess: Error accessing". If you then click on OK you can proceeed.

1.2c Netscape Navigator 2.0 for Microsoft Windows 3.1
-----------------------------------------------------

The teletype font works fine.

1.2d Netscape Navigator 2.0 for the Russian version of Microsoft Windows 95
---------------------------------------------------------------------------

See the discussion in pc_e.html on how the national characters are treated.

1.2e Microsoft Internet Explorer for Microsoft Windows 3.1
----------------------------------------------------------

This Web-reader works fine in both version 2.01 and 2.1.

1.2f Netscape Navigator Gold
----------------------------

This Web-browser (in version 3.0b6 for UNIX) works fine.


1.2g IBM Web Explorer using OS/2 Warp 3
---------------------------------------

This works fine. At local installation it is recommended to
unpack the ZIP-file with Unzip from Info-Zip.

1.4 Installation
----------------

The tutorial is now available either as a MS-DOS diskette
or as a single compressed ZIP-file or tar-file.

Main page, with links to all other pages is f77to90.html.
Pictures are in the subdirectory gifs and source code in
the subdirectory code. The chapters are c(digit).html
and the appendices are a(digit).html. All other document
names are self explanatory, except fortran.html,
which includes external links to other Fortran documents.

a) Installation from a diskette on Windows 3.x

At delivery on a diskette this can be used directly,
but I recommend installation on the disk memory with the command

xcopy a:\ d:\f77to90 /s /e /v

where a (or b) is the diskette unit and d (or c)
is the disk memory. My proposal for a directory name
is f77to90.

b) Installation from a compressed ZIP-file

You can obtain the tutorial as a compressed ZIP-file using anonymous
ftp from the computer nsc.liu.se (130.236.100.5) on the file
pub/bibliotek/f77to90.zip.

On your computer you put the file f77to90.zip on the directory
where you wish the subdirectory f77to90 to be created.
There you give the command pkunzip -d f77to90.zip on MS-DOS
and unzip f77to90.zip on UNIX. You then get the files installed
on one directory with the HTML-files, one subdirectory gifs
with pictures and one subdirectory code with the source code.

Under Windows 95 you have to use the program "WinZip for Windows 95"
in order to manage the long filenames. On Macintosh you unpack with
the program "Zipit", with the alternative "conversion to PC-files"
switched off.

c) From a compressed tar-file

You can obtain the tutorial as a compressed tar-file using anonymous
ftp from the computer nsc.liu.se (130.236.100.5) on the file
pub/bibliotek/f77to90.tar.Z.

If you have received the file on an MS-DOS diskette from me I name the file
F7TO9TAR.Z. When installing on a UNIX computer you are supposed to
change the file name to f77to90.tar.Z.

On your computer you put the file f77to90.tar.Z on the directory
where you wish the subdirectory f77to90 to be created.
There you give the commands uncompress f77to90.tar.Z followed
with tar xvf f77to90.tar on UNIX. You then
get the files installed on one directory with the
HTML-files, one subdirectory gifs with pictures and
one subdirectory code with the source code.

d) From a self-extracting Macintosh archive

The self-extracting Macintosh archive form of the tutorial is now available
using anonymous ftp from the computer nsc.liu.se (130.236.100.5) on the file
/pub/bibliotek/f77to90.sea.
