Jwin.opa (program file - ESSENTIAL) 
Jwin.txt (this file - DELETE AFTER READING)
Jwin.hlp (help file - EXTREMELY USEFUL)
Jwin.dat (Conversions Data - ESSENTIAL)
Quikcalc.ovl ("Quick Calc" module - OPTIONAL)

Please install the on-line help as this provides the best
guide to all of the programs features.  I don't like long
read me files because people tend to just skip them and end
up not knowing how to use the program.   To this end I've
tried to keep the file as short and as small as possible.
This means that none of the features are explained and that
there is no in-depth  "how to use me" guide.  However, all
of this is in the file "Jwin.hlp" and if you want to know
how to use JWIN then you NEED to install the help, after
all, once you get the hang of it the help can be deleted later!

INSTALLATION
************
Put Jwin.opa in the \APP directory on any drive.  Then create
a directory called \JWIN\ 1 deep in the directory tree 
(e.g. M:\JWIN\) on any drive.  Into this, put the
conversion file (jwin.dat), the help file (jwin.hlp) if you
want it, and also the calculator module (Quikcalc.ovl) if 
you want to use it.

NOTE: PLEASE AVIOD USING FLASH DISKS FOR THE \JWIN\ DIRECTORY
      AS WHEN JWIN TRIES TO COMPRESS IT'S FILES, MORE SPACE
      WILL BE USED

	When JWIN first starts up, it checks for the location of
the file "jwin.dat" in a \JWIN\ directory on drive M, then drive
A, then drive B and finally drive C (for Cyclone users).  If it
can't find "jwin.dat" in any of these places, it warns you and
the program will not run.  If it DOES find "jwin.dat" in one of
those places, it takes that drive to be it's location for files.

E.g. If you have a A:\JWIN\ directory with "jwin.dat" in it, then
JWIN decides that A is the drive it will use for all it's other
files.

	A file called "Jwin.ini" will be created in that \JWIN
directory, and this holds all of the crucial settings.  WHEN you
register a file called "Jwin.reg" is also placed in the \JWIN
directory so that the program recognises you as a kind-hearted,
registered user ;-)

NOTE 2: It is possible to have the .opa file on a DIFFERENT disk
        to "jwin.dat" and therefore all the other settings.

	E.g. put "jwin.opa" into A:\APP\ *BUT* create M:\JWIN\
	and into that put "jwin.dat" and "jwin.hlp".  This means
	that JWIN will use drive M (Internal) for it's files
	base, but it will actually be running on drive A!

As a result,  JWIN is very flexible as to where you want to have
it installed - the choice is basically yours.

About the Prog
**************
I wrote this prog because I wanted to have a collection of general
utilities that were useful and quick to access, but didn't take up
a huge amount of space.  After much development (spending far
much more time than I should have done on the code), I thought
that the program was in an acceptable state to be publically
released, and more importantly, to be of use to other Psion users.   

About the Author
****************
P.K.Spencer is a 16 year old from Aylesbury.  I have
limited OPL experience and I'm learning to write programs.
This is one of my first attempts and I have now managed
to reach quite an advanced level, this version is wildly superior to
any earlier versions. The Prog appears to have no bugs but if you
find any or have any comments/suggestions for future versions then
I welcome your input either by:

E-Mail on nicko@nildram.co.uk or 106023,676 on CIS

OR by Snail-Mail at :

Updates of Jwin (and all my other programs) can be found on my web

Disabled Features
******************
JWIN is FULLY WORKING shareware.  This meants there are NO, yes
that's correct NO, disabled features in JWIN while it's 
unregistered.  The only things you will see to remind you to
register are nag screens on start and exit and also every
time you switch to JWIN.  

Registering
***********
JWIN v1.3F is distributed as Shareware and you may use it
in it's unregistered form for 25 days.  If, after this
trial period, you find JWIN useful, then you MUST register.
To register the program on Compuserve, GO SWREG 13871, 
otherwise you must:

Send 5 UKP (10 USD) OR a foreign currency equivalent PLUS 10% to
my Snail-Mail address with either your E-Mail address or
with a an SAE.  This will enable me to send you your
personalised Key-Code to unlock the program's features
and banish the nags forever.  The final alternative is to use
the RegNet serive and register JWIN by going to:

http://www.swregnet.com/530p.htm

	When registered you will be entitled to any future
upgrades FREE,  you also get to take advatage of the new
versions before many users as all new versions will appear
on my homepage BEFORE they're released to other places (e.g.
CompuServe's Psion Forum).  You also get a direct say in
future developments and more importantly a clear conscience

5 UKP isn't a lot to register and it'll help me develop
future versions (and other programs). I don't have much
time free as I'm doing my GCSE's so I need an incentive :-)

A Brief "How to use me" guide
*****************************
When you first run JWIN, you'll se a screen with a summary
of your current System's info on it.  This is the main screen
of JWIN and provides a quick round-up of the Psion's Status 
at that moment!  Although it won't tell you much that the 
Psion itself can't, it does provide the info all on 1 screen.
This saves you having to go through several dialogs to find
what you want from the System Screen!

The usual keys of menu and help do their normal functions
and I URGE you to explore the menu fully.  The help carries
all the important details of the main functions of JWIN.

	JWIN has been designed to be left open all the time
and has been given the ability to detect a hotkey of it's own
without you having to assing one to it from the button bar. 
This hotkey is governed by the "Set preferences" section and
it's up to the user what they assign JWIN, the default is
Control-J.  However, this only works if you DO NOT leave
JWIN showing a menu or dialog.  If you can afford to (i.e. 
have spare System key combinations), then it's far better
and more reliable to assign JWIN a key from the Button Bar.

	All in all, JWIN is a very straight-foreward program
to use and it's very easy to get the hang of it and use it
to it's full potential.  Remember, if you do find JWIN of
use to you, then you MUST register after 25 days ;-)

Features
*********
- User configurable hotkey for easy and rapid switching to JWIN.
- Minimal memory usage - JWIN is designed to be left running ALL
  the time.
- Conversions between MANY of the most common unit values
- Find the day of the week a date falls on
- Find the number of days between 2 dates
- Quick Mini-Calculator
- Very user configurable via "Set preferences"
- MANY, MANY more ;-)

Thanks to...
*************
I would like to thank STEVE LITCHFIELD for his help and
suggestions.  ALEX WILBUR was also a *great* help in providing
me with bits of code for a)Quick Calc and b)the hotkey function.
Also, JOHN BOYCE for beta testing on a "real" Siena and HANS
TROMP for help in re-designing certain parts of the code from
v1.2x, and also his testing and suggestions!  My other beta
testers also appear ;-)) to have done a good job.

	c) Fixed bugs in Quick Calc for decimal point on Siena
	d) Fixed a few bugs in the conversions data file and also

	   module which will be released later.
