1. Quick Key Reference

   [WINDOW] - File Menu
   [ZOOM]   - Edit Screen
   [TRACE]  - Tools Menu
   [GRAPH]  - Quit
   [UP]     - Scroll Up
   [DOWN]   - Scroll Down
   [2nd]    - Quit Program / Quit Menu
_______________________________________________________________________________________
2. Installing Spreadsheet DE

   To install Spreadsheet DE on your TI-83/+, you need to transfer two programs to your
calculator, SPREAD and ZEXLOGO.  To run the program at any time, just run SPREAD.
You do not need to install this program at all; it will self-configure to your
calculator.
_______________________________________________________________________________________
3. Using Spreadsheet DE

   To use Spreadsheet DE, run SPREAD.  This will bring you to the title screen.  Press
[ENTER] to proceed to the main program.  You will be presented with a blank document.
To open a file, press [WINDOW], arrow down to Open, and hit [ENTER].  You can choose
a spreadsheet or press 2nd to escape.
   To edit the current cell, press [ZOOM] and then type the value you want.  From 
here you can use the Recall command to paste the contents of variables.  Press [ENTER]
when you are done.  To save a file, go to [WINDOw] (from now on referred to as "File",
arrow down to Save and choose the file that you wpuld like to save the current
document as.
NOTE: If you already have a file in this slot, it will overwrite it.
   To open a file that you have previously saved, go to "File">Open, arrow down to the
appropriate file, and hit [ENTER]  if you decide not to open a file, press [2nd] to
exit the menu.
   To use the Tools Menu, go to "Tools" by pressing [ZOOM].  There are two options,
Word SUM and PRDCT.  Use the arrow keys and [ENTER] to select a function, or press
[2nd] to quit back to the main screen.  SUM will ask you for a range of cells (row,
column,row,column) and then return the sum of the values of the cells to the current
cell.  PRDCT will ask you for a range of cells (row,column,row,column) and then return 
the product of the cells to the current cell.
_______________________________________________________________________________________
4. Salvaging Lost Files

   If you have accidentally deleted SPREAD or ZEXLOGO and need your files before you
have a chance to reload the program onto your calculator, you can access them.  On the
homescreen, press go to the matrix menu and then the file letter of the file you need.
For example, [A] is file 1, [B] is file 2, etc.  Press [ENTER] and then use the arrrow
keys to browse the spreadsheet.
_______________________________________________________________________________________
5. Sharing Files Between Calculators

   Spreadsheet DE will soon support file sharing between calculators from within the
program; until this is implemented, you can share files using the Link function of the
calculator.  Go to [2nd][X/theta key], choose Matrix... and then choose the matrix
corresponding to the file you would like to send.

and detail the problem.  I will fix this as soon as I figure out what is causing it.
If you discover any other bugs or errors, please email me and I will put them and their
