A.) Special notes to users of ISETLW 1.x, 2.0 beta versions

The file ISETLW.INI is no longer an include-able file.  DO NOT !INCLUDE 
ISETLW.INI.  It is recommended to install version 2.0 in a new directory to 
avoid overwriting any existing ISETLW.INI file.

If you have an ISETLW.INI file, it is recommended to rename it to a .STL file 
(such as ISETL.STL or ISETLW.STL) to avoid confusion between ini files and 
!include-able files.  You may then have the file !include-d automatically at 
startup.  See online help for details.

B.) Contents of ISETLW20.ZIP

The following files are contained in ISETLW20.ZIP:
ISETLW.EXE              (executable Windows file)
ISETLW.HLP              (ISETLW Windows help file)
BC450RTL.DLL            (Borland run-time routines)

////////////////////////////////////////////////////////////////////////

C.) The ISETLW.INI file

1.) Function of ISETLW.INI
ISETLW.INI is a standard Windows initialization file (ini file).        
If present, this file contains options customized during a session of ISETLW.

2.) Location of ISETLW.INI
ISETLW will look for ISETLW up to three times, in the following order:
1.) The program directory       (where ISETLW.EXE is running)
2.) The current directory       (Window's working directory)
3.) Window's directory          (from where WIN.COM was run)

As soon as a copy of ISETLW.INI is found, ISETLW stops looking and reads this 
file.

3.) If there is no ISETLW.INI
If ISETLW.INI is not found, the user is given the option of:
1.) Creating ISETLW.INI in the program directory
2.) Creating ISETLW.INI in Window's directory
3.) Looking for an extraneous ISETLW 2.0 ini file
	
If option (3) is selected, the user can:
1.) Browse for ISETLW.INI in a location other than the above three.
2.) Browse for an ISETLW ini file under another name.
3.) Create a new ISETLW ini file (by entering a filename which doesn't exist).
4.) Bypass using an ini file (by clicking CANCEL).

4.) ISETLW.INI contents
The following are ISETLW.INI entries
ENTRY                MEANING                       DEFAULT
Font                 Name of font to use           Times New Roman
Include              Files to !include             isetl.stl
Timing               Calculation timing            off
Buttons              Buttons for toolbar           Open,Save,Print,Run,
						   Interrupt,Undo,Cut,Copy,
						   Paste,Exit
WorkDirectory        (See below)                   none

5.) The WorkDirectory
If a directory is specified in the WorkDirectory entry of the ini file, then 
ISETLW will attempt to use ISETLW.INI in the directory specified.  If this 
file does not exist, it is created silently with the default options.

6.) Example ISETLW.INI file
[OPTIONS]
Font=Times New Roman
Include=ISETL.STL;
Timing=0
Buttons=1;3;5;7;8;10;11;12;13;9;

[INI]
WorkDirectory=

This ISETLW.INI file will set up ISETLW to:
  Use the Times New Roman font
  Excute the file ISETL.STL automatically (see below for sample ISETL.STL file)
  Initiallly turn off calculation timing
  Create default buttons (see above)
  Not search for another ini file

D.) The ISETL.INI/ISETL.STL file 

1.) The ISETL.STL file
ISETL.INI is a file that can be executed by ISETLW with the following command:
   !include isetl.ini
It is recommended that the name of this file be changed to ISETL.STL to avoid
confusion between and !include file and a windows ini file

The ISETL.STL file can be used to !include standard routines, such as the 
graphings routines (.stl files) included in this download. This ISETL.STL file
can then be !included automatically at startup.  See ISETLW online help for
details.

If you are a user of ISETLW 1.x or ISETLW 2.0b1, you will need to rename your
ISETLW.INI file to ISETL.STL and copy/move it to the ISETLW 2.0 directory.

2.) Example ISETL.STL file
!echo off
!memory 8000000
!include axis.stl
!include zoomer.stl
!include donplot.stl

This ISETL.STL file (which is !included in the above ISETLW.INI file) 
instructs ISETLW to:
  Turn off echoing (if echo is on, each line of the three following files is
     echoed to the screen.
  Set a memory limit of 8MB
  Include the graphics files axis.stl, zoomer.stl, and donplot.stl
