good idea --> I will this add so

Problem still is, that a record can changed too.
Record are sorted. Now, they are stored as double linked list (using the Atmel Demoboard with rewritable DataFlash).
I think, at first I must isolate the list order/index from data.
In this way, the index (or list or tree) must stored separatly.
Now the same problem: the many often changed values must "roll over" the flash area. So I need a mapping to used pages/blocks with the latest valid index data.
