Do also notice that the string type has a copy-on-change functionality:
var
S1,
S2: string;
begin
S1:='Some incredibly long string, maybe MB''s of length';
S2:=S1; // S2 now points to S1, only one instance exists in memory. The
string has a refcount of 2.
S2[1]:='X'; // S2 is now copied into a newly allocated string, both S1 and
S2 having a refcount of 1.
