The program is modelled after Microsoft Excel, so a book on Excel should be able to help you. There are lots of web sites that offer information and tutorials on Excel, such as http://www.microsoft.com/insider/learning/default.asp. If you have any specific questions about the functions, then I will be glad to answer them and/or provide examples.

You need to delete the Shareware version from the device and copy over the Registered version. You will not be able to delete the Shareware version while it is still running, so activate the program and use the File Exit menu option to shut it down, or do a soft reset of the device to shut down all active programs. Then copy over the Registered version which you should have downloaded from the URL provided at the bottom of the registration confirmation message from Kagi.

The only difference between the Shareware and Registered versions is that the Shareware version has a message that is displayed each time you use one of the File menu options.

When a new version is published, the updated version will be sent to you automatically by e-mail (you must provide an e-mail address that can receive executable attachments to messages where your e-mail address will be in the Bcc field). If you do not receive the updated version the please let me know and I will send it to you again.
Possible reasons for not receiving the updated version are:
- the e-mail was not delivered
- the e-mail was intercepted and rejected by over-enthusiastic spam/virus filters operated by your e-mail service provider
- your e-mail service provider does not allow you to receive e-mail containing attachments
- your e-mail address has changed

To turn off the conversion, on your desktop PC...
1) Start the Microsoft ActiveSync program (it should be on your Start>Programs menu, or just double-click the icon in the system tray that looks like a circle containing two arrows).
2) Select the Tools>Options... menu option.
3) Select the Rules tab.
4) Press the Conversion Settings button.
5) Select the Desktop To Device tab.
6) Select Microsoft Excel Worksheet in the list box.
7) Press the Edit... button.
8) Select No Conversion in the drop-down list box.
9) Press OK.
10) Select Microsoft Excel Template in the list box.
11) Press the Edit... button.
12) Select No Conversion i the drop-down list box.
13) Press OK, OK, OK.

If you would like more than one copy of the program then volume discounts are available as follows:

20	5.00
50	3.50
100	2.50
200	2.00
500	1.50
1000	1.00

100000	0.30

Note that these licenses are for OEM (i.e. hardware vendors) or end-user (multiple copies at one site) use, and may not be offered for sale to the public. Decide how many copies you want and pay in advance directly to me (not via the Kagi web site) either by check or wired directly to my bank account (mail address and account details available on request) and I will send you the Registered versions by e-mail. The total number of copies can be made up from any combination of versions of the program.

No. You will need to do one of the following:
1) Use the zoom facility to make the data smaller
2) Use the Data Form menu option to display the data
3) Use a separate display driver such as is available from
http://www.nyditot.com
or
http://www.jimmysoftware.com/Software/PowerToys/Landscape3
4) Get an HPC instead

Not yet, and probably not for a long while. But while you're waiting, you could try one of the following:
MiniCalc from http://solutionsinhand.com/
Quicksheet from http://www.cesinc.com/
SheetToGo from http://www.dataviz.com/
TinySheet from http://www.iambic.com/english/index_ie.html

No. It will not be possible to make a Smartphone version for now. The main problem is that much of the required operating system functionality is missing from the Smartphone version of Windows CE. A brief look at the documentation shows no support for:
touch-sensitive screen
file open/save dialog boxes
combo boxes
property sheets
toolbars
cut/copy/paste operations
I would have to write all of the missing components myself, and this would take too much time.

No, but try http://www.tucows.com

To make the file association,
1) from Windows Explorer use the Tools>Folder options menu option,
2) select the File types tab
3) if XLS is in the file extension list then select it and press the Change button, if XLS is not in the list then press the New button and enter it
4) press the Browse button and locate the Spread32 program

You will need to set up a file association to link files with the xls suffix to the program spreadce.exe. A file manager application should be able to do this for you. If you do not have one already on the PDA, for HPC 2000 devices download the PowerToys utility from http://www.microsoft.com/downloads/details.aspx?FamilyID=8b0788f7-bedc-4e3e-9c08-78b176152f44&DisplayLang=en
For other devices try Pocket Tweak, from http://tillanosoft.com/ce/ptweak.html

You will need to ensure that you have a 'My Documents' folder on the storage card, and files must be stored in this directory or one directory level below it, as that is the only place that the standard file open and save dialog boxes will look.
