This is the manual for Separate-Chex for the Newton.  This is proto-ware 
written by Kyle Huang  (cosc19vs@menudo.uh.edu).  That means, the author (me) 
just wrote it get his monthly telephone bill divided equally among his 
roomates.  If you like it and would like to see a full shareware version, 
please send in a request for the author to finish the shareware (either at

Description:  

Separate-Chex is made for the sole purpose to help divide restaurant checks, 
telephone bill, grocery bills, and other multiple party bills.  This was made 
to help my roomates and I to fairly divide the phone bill without wasting 
time.  Not only can you separate the final bill to 4 people, but this program 
will fairly separate a lump tax among the people  (that is, say #1 order a 
plate costing $10.00, and #2 ordered another plate for $20.00; Separate-Chex 
will divide a $3.00 tax into $1.00 for #1, and $2.00 for #2).


Instructions:

1.  Users can enter values on the input line (also, you can double tap for 
the system number keypad).

2.  The top part of the program is a simple calculator.  The following 
buttons are part of the calculator "ce", "x", "+", "-", "÷", "±"and "=".

2.  There are four buttons that add data from the input line.  Each time one 
of the four button is pressed, whatever value in the input line is added to 
that button.  

3.  The gray button at the bottom of the four "account" button sums the 
values of the buttons.

4.  Selecting the "Single check box" will erase the input line once a button 
processes the input line.  (Useful when you have many different priced items; 
or turn it off when you have many of the same items for each people--ie, if 
everyone orderes the same dish.)

5.  Selecting the "Preview check box" will let users to lock/unlock the 
previews (the numbers on the right of the buttons).  Useful for people that 
calculate tip values before taxes--that is, they can turn on the preview 
boxes, insert the % value, press preview, and turn off the preview check box 
to lock the previews in place.

6.  The "% Tax" aka "# Tax" button tells the program if the value under it is 
a percentage tax to add or a discrete value to add.  If it is a percentage, 
the program will apply only a positive percentage on the values with the 
press of the "Add Tax".  If it is a number, it will fairly divide the value 
under this button among the four accounts (note, an account without a value 
in will not have to pay any tax).

7.  The "Preview" and "Add Tax" (and "Sub Tax") buttons let you look at the 
value of the tax before you add it AND lets you add the tax with respect the 
"% tax" or "# tax" value, respectively.  Note:  if you plan to use the 
preview button, make sure that the "preview check box" is checked.  
Note:  if you are using "% Tax", doing a "Add Tax" and then a "Sub Tax" 
IS NOT undo, and doing a "Add Tax" then "Sub Tax" is not the same as doing 
a "Sub Tax" then a "Add Tax".  Use the preview button before you apply the 
function to be safe.

8.  The "Rnd" buttons.  Like the value below the "% Tax" aka "# Tax", the 
value on the right of the "Rnd" button denotes the decimal positions to 
round off to, ie. 1 rounds to 0.0, 2 rounds to 0.00, 3 rounds to 0.000, 
etc.  When you decide to round off, press the "Rnd" button.  Note: a 0 value 
does not round. 

9.  The "AC" buttons clears all values (including tax values, round values; 
excluding check boxes).

10.  The "?" button gives program information and registration instructions 
in unregistered versions.  

11.  The "move" button (looks like 4 arrows on the bottom) gives information 
about the enhancements in the registered version.

12.  The "minimize" button (looks like 2 arrows pointing down) minimizes the 
program into a small button.
