0. About
========
This program is FREEWARE, you may copy and spread it, as you want, but
you MUST NOT earn money with it.
If you give this program to someone else, you have to copy the whole drawer,
that means, it must consist of:
 - the source
 - this document
 - a working copy of CFormat

1. Hardware
===========
Solve runs under Kickstart 1.2 and 1.3 (2.0 ?). It needs 512kB, the stack
should be about 20000 bytes. In LIBS: must be:
                  - mathieeedoubbas.library
                  - mathieeedoubtrans.library
                  - tool.library

2. Introduction
===============
Solve is a program to solve equations of fourth degree. Solve can only be used
from CLI, SolveI is a version with intuitioninterface, you can use it from
Workbench, too.

3. Working with SolveI
======================
Start it with a double click. A Screen with 5 little gadgets appears. Here you
can enter you coefficients.
The big, emtpy part of the screen is used to show the solutions. All solutions
are displayed in real and imaginary part and a difference to zero. (That is the
value computed with the solution. It should be zero).

4. An example
=============
You want to solve the equation 4x^4+2x^2+3=0. So enter 4 RETURN RETURN 2 RETURN
RETURN 3 RETURN. Four solutions should appear.
If the coefficients are very big (eg. x^4+1250x^3+x^2+2x+3=0), the solutions
seem to be not correct. Try the example. The last solution will be
-1249.9992013 with a difference to zero of 5*10-8. Use only x=-1249.999201
and calculate x^4+1250x^3+x^2+2x+3. You will get something like -547.....
and it should be zero. Not very good. If you use x=-1249.999202, you get 1409.
If your pocket calculator even works with the last digit, try x=-1249.9992013
and you will get 41. So the printed solutions is correct. For the calculation
of the difference, the whole solution (with all digits) is used, but only 6
digit after the point are displayed.

5. The menus
============
 - About
    Displays a window with some information about the program etc. Click in the
    window to close it.
 - Clear
    After a request to the user, the gadgets are cleared, the curor is in the
    first gadget.
 - Quit
    After a request, the program ends.

6. Use Solve from CLI
=====================
Solve has no intuition interface, so it asks all values from the user.

7. Compilation
==============
A MAKEFILE is in this drawer. Use LMK Solve to get the CLI-version, LMK SolveI
to get the intuition version. Komplex.lib and tool.h are needed.


                             That's it. Have fun !
