Hm... I think that MoveChars copy a string to another string, but
maintaining the contents of the second string (I'm without delphi for
test it).

So, I'll try to explain my problem ...

I am needing to move a string to another string, eg:

var
  d, s: string;
begin
  d := 'the on the table';
  s := 'books ';
  SetLength(d, Length(d) + Length(s));
  Move(s, d[4], Length(s));
  writeln(d); // the result should be 'the books on the table', but I
get 'the|?S  |?e table  ?'
end;

I could easily do this using "copy", but I'm trying (without success)
to do this at low level.

Thank you Jonas! :)
