You can forget that 255 character stuff
- also String /Data/ is not on the Stack
- the pointer to the String Data might or might not be on the stack
depending on where and how the String is Dim-ed

It is not how it works

Try the following :
Me.Print VarPtr( S )
Me.Print StrPtr( S )

You seem to have picked up some information on how Delphi handles
Strings - VB does not work like that at all
