This document gives you instructions on how to install, start, and remove 
the FLEX software for several IBM-PC operating systems.  The abbreviated 
instructions on the diskette only cover installation under the DOS 
operating system.  The four operating system environments covered in 
this document are:

1) DOS
2) Windows 3.1 or 3.11 hosted by DOS
3) Windows 95
4) OS/2

In this document we use the convention <string> where string is something
to be entered with the keyboard.  If the string entered is a command to the
operating system, a Carriage Return (CR) key is assumed to be pressed after 
you enter the string.  The convention [name] is used to identify things by
literal name (like names of icons and menu items).

******************************
* Did you Download FLEX.ZIP? *
******************************

If you downloaded this program from a BBS or from the internet, you 
will need to make an installation diskette before you can install
the program correctly.  It's a good idea to make an installation diskette
anyway just in case you need to reinstall, or you want to install FLEX 
on several computers.  On the BBS, FTP site, or WWW page you should 
find the two files:

README.TXT   (introductory material)
INSTALL.TXT  (THIS FILE)
FLEX.ZIP     (pkzipped version of the following)

  - README.TXT          (release notes, disclaimer etc...)
  - INSTALL.TXT         (this file)
  - INSTALL.BAT         (the installation batch file)
  - FLEXZIP.EXE         (self extracting executable for the FLEX program)

Unpack the FLEX.ZIP file onto a 1.44Mb 3.5" floppy.  You will need
a copy of PKUNZIP.  Since you got this electronic copy, I'll assume
you are savy enough to know what that is -- and how to use it.  Once 
you have your installation diskette, log to that drive and type:

<install c:\flex>

where <c:\flex> is the path where you want to install the program.
See the readme.txt and the extensive context sensitive help for 
more instructions and help on running the program.

Alternately, you can PKUNZIP the FLEX.ZIP file into a temporary 
directory on your hard disk and run the install batch from that 
directory.  Once FLEX is installed, you can remove the files from
the temporary directory.

**************
* In General *
**************

Installation of FLEX on your hard drive only adds a new directory tree, it
does NOT effect any other files on your disk including your AUTOEXEC.BAT, 
CONFIG.SYS, or Windows INI files.

->-> INSTALL <-<-

1) Put the program diskette in drive A: or B: and change the default drive to
the diskette typing <A:> or <B:>.

2) Type <INSTALL C:\PATH> and press the Enter key to install the software 
to the PATH you specify. For example, if you wanted FLEX to be installed 
the C:\FLEX directory type: <INSTALL C:\FLEX>.

3) The installation will copy all the necessary files from the diskette and
create the pathname you specify along with several subdirectories for support
files and sample input files.

->-> START <-<-

1) Log to the directory containing the FLEX.EXE file by typing <cd path>
where path is the name of your FLEX directory.  If you are running the
program for the first time, you may want to view the contents of the
README.TXT file.  This file is in simple ASCII format so you can use your 
favorite word processor or text editor to view this file.  It contains last
minute notes not found in the on-line help material.

2) Type <FLEX> to start the program.  You can also place the FLEX directory 
in the PATH statement of your AUTOEXEC.BAT file (i.e. PATH=C:\FLEX) and be 
able to start the program from any disk drive or directory on your system. 

3) Use the Setup main menu in the program to specify the directory pathnames 
where you want the program to look for input data and where to write its 
results. Default data and output directories are created during installation.
However, you can use this feature to locate your data and output results
in any directory path.

->-> REMOVE <-<-

If you want to remove the program including all of its subdirectories and 
files, you can use the provided REMOVE.BAT file.  FLEX does not effect any 
files outside the directory path where you installed it, so you can be 
certain that the remove batch file has deleted everything.  CAUTION:  If 
you have spent any effort entering data it would be a good idea to backup 
your data directory first!

**************************************  
* Windows 3.1 or 3.11 hosted by DOS *
**************************************

->-> INSTALL <-<-

If you are running Windows 3.1 or higher in 386 Extended mode, 
you can run FLEX from a DOS window. If you would like to install 
FLEX as a program item, a program information file (.PIF) and 
icon file (.ICO) are provided. To install FLEX as a program item:

1) Select the program group you want to install FLEX in (e.g. Double click on
the [Applications] program group) 

2) Choose [File/New] from the Program Manager main menu. 

3) Type <FLEX> as the Description String; type <FLEX> as the 
command string; and type <C:\FLEX> for the working directory (or
whatever you labeled the directory at installation). Windows
will assign a default icon and add this as a program item. 

4) Chose [File/Change Properties] and press the [Change Icon]
button. A message about 'no icons available' will appear 
ignore it and press the OK button. 

5) An icon change window will appear. Type <C:\FLEX\FLEX.ICO> 
for the file name at the top of the form. The FLEX icon will 
be assigned.

->-> START <-<-

1) Open the program group where you have installed FLEX and double
click on the FLEX icon to start the program.

2) If you have not installed FLEX into a program group, open the [Main]
Windows folder and double click on the MS-DOS icon to open a full screen DOS
window. Change directories to the FLEX directory and type FLEX to run the
program.

You should be able to use the regular <ctrl-esc> and <ctrl-tab> keys to
navigate between FLEX and your other applications.  Be sure to see the note
about Windows delays.

WARNING: WHEN YOU EXIT FROM FLEX AFTER A WORKING SESSION,
WINDOWS MAY TAKE A LONG TIME TO RELEASE THE MEMORY ASSIGNED.
THIS LONG WAIT (UP TO 1 MINUTE) MAKES IT APPEAR THAT YOUR 
COMPUTER HAS CRASHED. BE PATIENT AND WINDOWS WILL RETURN EVENTUALLY.

WARNING: WINDOWS CAN EXHIBIT STRANGE SYMPTOMS IF THE GRAPHICS 
MODE USED BY A DOS-BOX APPLICATION DOES NOT MATCH THE GRAPHICS MODE 
USED BY WINDOWS. IF YOU WANT TO SWITCH BACK AND FORTH BETWEEN FLEX AND
WINDOWS WHILE FLEX IS RUNNING, YOU MUST MATCH THE GRAPHICS MODES.  FLEX USES
STANDARD VGA (640X480X16 COLOR) ON STARTUP

->-> REMOVE <-<-

1) Open the MS-DOS box from the [Main] folder in the program manager.

2) Change directories to where you have installed FLEX, then type REMOVE.

3) Follow the instructions in the batch file to remove all of the FLEX files
from your disk.  FLEX does not place files anywhere else on the disk, so
you can be sure the program has been removed.

4) If you have installed FLEX as a program item (ICON)  in another program 
group, be sure to delete the icon by highlighting it and select 
[File/Delete] from the program manager main menu.

***************
* Windows 95  *
***************

->-> INSTALL <-<-

1) Double click on [My Computer] icon.

2) Double click on the [Control Panel] folder.

3) Double click on the [Add/Remove Programs] icon.

4) Click the [Install] button.

5) Place the installation diskette into drive A: You must have a 1.44Mb 
high density disk drive as drive A: since Windows 95 only looks for
installation programs on the first diskette or CD-ROM drive.

6) Windows 95 should find the A:\INSTALL.BAT file. Press the <End> edit key 
on your keyboard and add the desired path name so it reads:
A:\INSTALL.BAT C:\PATH
where C:\PATH is the name of the disk drive and path name where you
want the program installed.  For example, if you want the program
installed in the FLEX directory of your C drive, type 
<A:\INSTALL.BAT C:\FLEX>

7) Press <Enter> or click on [Finish] to begin installation. 

8) Windows will open a DOS box and run the installation program and copy
all files to the path you have specified.  When the file copy stops,
click on the [X] button in the upper right corner of the window to close
the DOS box.

9) Close the [Control Panel] folder.

->-> START <-<-

1) From the [My Computer] icon, double click on the drive where you have
installed the program.

2) You should see a folder for the program.  Double click to open the folder.

3) If you are running the program for the first time, view the contents 
of the README.TXT file by double clicking on the [Readme] icon.

4) To start the program double click on the MS-DOS shortcut icon.

->-> REMOVE <-<-

If you click and hold the FLEX folder and drag it to the recycle bin, it 
will automatically remove all FLEX files and directories.  CAUTION:  you 
better backup you data before doing this, because there is no way to 
restore the folder once it goes into the recycle bin.

<INSTALL C:\PATH> where C:\PATH is the directory path name where you want to
install the program.

5) When the installation batch file is completed, close the DOS window by
typing <Exit>.

6) Can stop at this point, and simply run FLEX from the [DOS Full Screen]
command prompt, or you can migrate the application and have OS2 assign it a
program object and folder.

7) To migrate FLEX, Open the [OS/2 System] icon and double click on the
[System Setup] icon.

8) Double click on the [Migrate Applications] icon. In the check box area,
only check the [DOS programs] box. Then press [Find].
