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 his e-mail address or mailing address--Kyle Huang; 1044 Camino La Costa #2063; Austin, TX  78752).  

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.
