Oh, and I tryed to invent 's' and now I understand why my STOP doesn't

If I use 'o' what are the meaning (till now I found) of S:s:D:d: s: 
S: = Static PUBLIC 
s: = Static (PRIVATE)
D: = PUBLIC Declaration
d: = Declaration (PRIVATE)

Is that right ? Are there something for CONST or some others further
more?

Dit you mean to replace the Baloon by the window ? And then, if possible
go further ?

So first I have to rewrite Debug_Read, because it is wired (l?!) to a
Table in DebugInfo
