Help with Hero(n)'s Formula v1.1 by Keller Davis (keller22@aol.com)
-------------------------------------------------------------------

  I don't really see the need for a help file but I made one just for
the heck of it. Besides it's not like any one will ever read it.  

What is Heron's formula?
Heron's formula is  a formula which when given the 3 sides of a 
Triangle, it can tell you the area.  The formula it self is:
(A+B+C)/2=S
_  ___________________
 \/S*(S-A)*(S-B)*(S-C)

In the formula S is equal too half the perimeter.

When you enter 3 sides of a triangle which couldn't exist (for example:
1,2,500 or any triangle that A+B is less than or equal to C) it will go
back to the starting point of the program.  
When it displays the answer it displays it in 2 ways, the radical and
the decimal answer.  It also say "Simplify radical?".  You can either 
press F1 or F2  for yes or no.  If you pick yes you it will put the 
radical in simplest terms.  It may take a little while if the number is
big.

Please feel free to change any thing in the program but please send me
the new version!!  Also please please please tell me if you have found 
any mistakes in it!!!!  By using this program I am in not in anyway 
responsible for any damage it might to you calculator or subject using
the calculator.  If you have any other questions you can email me at
