Question

I am using this code to check whether TStringList is created or not:

procedure TForm1.Button1Click(Sender: TObject);
var

  sVariable : TStringList;
begin
   if not Assigned(sVariable) then
   sVariable:= TStringList.Create;
end; 

But the condition is False always, why does that happen? How do I check if TStringList object is created or not?

P.s. I am aware of a similar question asked, I tried the solution posted in that one, but it is not working for me.

You can assume that the object is not created and the variable initialized with garbage (because it’s a local variable). Just create your StringList and everything is fine.
