To return to the original subject, I'm concluding that your designs are based on the experience and your clear minds and do not follow any popular design methods. Still I think it is good to have such design methods in mind when a design is made where it is possible. We only start to write in assembly or try to think of very sophisticated but less understanding code for others, when we run into timing or RAM size problems. I thought that more designers where using this approach. Nevertheless it is good to know how others think about it. Thanks all for your reactions.

Greetings Dennis.
