The idea was a tool or method, which would produce monthly payments from a capital, like a normal monthly salary.

 

It should take a little while until the work would start towards the idea. In 2000 I started to implement formulas and functions into Microsoft Excel.

 

Soon I realized if this should work the way I sought, it will need more than just a script and function language.
