                         SPC Tennis 
           =======================================

'SPC Tennis' is a simulation tool which should be useful to anyone 
who wants to explore Statistical Process Control.  It can give a 
feel for handling the variation which accompanies every process.  
It also provides experience in using Shewhart control charts.

'SPC Tennis' can be run on any computer which has the 'Windows' 
operating system.

'SPC Tennis' can be copied and distributed without restriction 
for appraisal purposes.  A screen will appear from time to time 
to remind you that you are using unregistered software.

Except for testing and appraisal, this product must be registered
before it can be used in any type of training establishment or 
any type of workplace.  It must not be used unregistered as part 
of a training course or be available on a machine which can be 
used by many people.  

For details of how to register, contact one of the distributors 
listed in the file 'Agents.txt'.

Packing List
------------
The following files are included in the package:

  TENNIS.EXE   (the executable file written in Visual Basic 3)
  CMDIALOG.VBX (a Microsoft file needed for the Open File dialogue box)
  COMMDLG.DLL  (a Microsoft file needed for the Open File dialogue box)
  GRID.VBX     (a Microsoft file needed to display tables)

  README.TXT   (this file)
  TUTORIAL.TXT (a tutorial)
  TUT1.VAR     (a variation file to use with the tutorial)
  TUT2.VAR     (a variation file to use with the tutorial)
  INSTRUCT.TXT (detailed instructions for use)
  TECHNICL.TXT (technical notes on the .VAR file structure)
  VPROGxx.VAR  (9 more variation files)
  NORMAL.VAR   (3000 results which show a stable normal distribution)
  UNSTABLE.VAR (3000 results which show some lack of stability)
  AGENTS.TXT   (a list of distributors appointed to sell SPC Tennis)

(the first four files on the list plus VBRUN300.DLL are needed for 
the programme to run)

VBRUN300.DLL
------------
This is a Microsoft file which is needed for any programme written 
in Visual Basic 3 to run.  This has not been inculded in the package
because many people have it already on their systems and it would 
increase the size of the package.  It is widely available on FTP 
sites and Bulletin Boards for downloading. For example, it is 
available under the name vbrun300.zip (zipped) at OAK.Oakland.Edu 
in directory SimTel/win3/dll.


Installation
------------
The files CMDIALOG.VBX, COMMDLG.DLL, GRID.VBX and VBRUN300.DLL
are "Shared Application Resource" files. These are Microsoft 
files which could be needed by any Visual Basic programme. 

Strictly speaking they should be put in the "Windows\System" 
directory to make them available to any future Visual Basic 
programmes that you may install. This avoids having more than 
one copy on your computer.

Leaving them in the same directory as the rest of the files
in the package avoids the need to check to see if any of the 
shared files are already in the System directory (older 
versions should be replaced). Leaving all the files in one 
directory also means that you can delete the directory and leave 
the computer exactly as it was before the files were installed.


Tutorial
--------
The best place for everyone to start is the tutorial.  Load 
TUTORIAL.TXT into Windows Notepad or a word processor then 
follow the step-by-step instructions.  As well as leading you 
through some of the features of the programme, the tutorial will
give a brief introduction to the use of control charts. The
tutorial requires you to load the files TUT1.VAR and TUT2.VAR into
'SPC Tennis'.

Instructions
------------
The programme has on-line instructions. You can get these from 
the menu bar or by pressing F1 in the main window.  More detailed 
instructions are contained in the file "INSTRUCT.TXT" on the 
distribution disc.


REGISTRATION
------------
After the programme has been registered, the 'Reminder' warning 
screen will not appear.  To allow study away from the workplace, 
employees of organisations which have purchased site licences 
are permitted to use the programme on their own equipment at home.

This computer programme is protected by copyright law and 
international treaties.  Use of this programme except as agreed 
by the copyright holders is prohibited and may result in severe 
civil and criminal penalties.
