Hi, yes I tried this too but I missed the step to create a new object than ;-).
I thought I can dynamically alter the third block. But this doesn't work. IMO
this would be a very elegant functionality.

Sounds like an object-altering dialect is needed ;-).

But only if the origianl object-layout is available. But that's not the case,
within my application I only have the latest version encoded. So I need to alter
the old objects step-by-step to the new ones. And I try to make it in-place
without copying around to much. Robert
