Resistor Color Coder Documentation
----------------------------------

I wrote this program because I was sick of the resistor color
code table.  RCC uses a graphical interface with very fast cursor
selecting to let you choose the stripe colors of a resistor and will 
then display its value.  It will also let you enter the numeric value 
of a resistor and will display the stripes the resistor should have.
 
The idea for the program came from a resistor value program I saw on
one of the goodies disks.  I like the idea for the program and knew that 
the user interface could be greatly improved.

Instructions for use
--------------------

Upon starting RCC, the screen will show you all of the resistor colors
in a box in the center of the screen.  On the right side of the screen is
a box showing the chosen colors of the three resistor stripes.  Another
box on the right side will show you the value of the resistor, with a label
of the appropriate units (K or M).   There will also be a label above the  
A & B keys saying "Enter Value".  Pressing either A or B at any time
will let you enter a numeric value for a resistor and the program will
instantly give the colors for that resistor.

Use the cursor keys to zoom around the color box.  Press return to select
a color and you will see it appear on the right-side box and the value
of the resistor in the bottom right corner will updated.  A marking 
cursor will be in the right hand box showing which stripe you are
currently choosing a color for (1, 2, or 3).  

Pressing NXT at any time will increment the stripe marker to the next stripe.  

Pressing ON will quit RCC.

Pressing either A or B will enter the input subroutine.  In the last line
of the display where the menu is normally displayed, a prompt will appear
and ask you for the resistor value.  The value you time will appear on
this line.  You may not enter values in kilos or megaohms.  You may however
enter the numbers in scientific notation.  The only valid keys during
this part of RCC are the numbers and the EEX key because those are the
only keys needed.  After entering a value, press return.  All values on
the display will be updated.  

Numbers entered for resistor values will be rounded sometimes.  This is
because it is not possible to use the color code for a resistor of say
5.4 ohms or 5.6789E6 ohms.  The program must round it.

This is all you need to know to run RCC.


Key Summary
-----------
Cursor Keys - move around the color chart
NXT         - move to next stripe 
A or B      - enter numeric value of resistor

I hope you like RCC and would love to hear any comments or suggestions you
might have.  I can be reached at : jeoff@tamsun.tamu.edu

Many thanks to:
	Detlef Mueller and Raymond Hellstern: for testing and great talks
	Rick Grevelle:  for all his tips and for being a good friend
	Mohammed Fatri: for writing the initial graphics routines



This version of RCC has been speeded up and improved a little.  The
highlight bar works a little differently and the clock is automatically
disabled. 

This version will run on any G or S series HP48.
