Position Example
The following program code demonstrates how to get the position of an item in a TMult variable:
procedure TForm1.Button1Click(Sender: TObject);
var
Mult: TMult;
begin
{Create Mult. Make Form1 its owner}
Mult := TMult.Create(Form1);
Label1.Caption := 'The position of the Third element is ' +
{will be -1 since the list is empty}
IntToStr(Mult.Postion('Third'));
Mult['Second'] := 'Two';
Label1.Caption := 'The position of the Third element is ' +
{will be -1 since 'Third' item does not exit}
IntToStr(Mult.Postion('Third'));
Label1.Caption := 'The position of the Second element is ' +
{will be 0, TMult positions start with 0}
IntToStr(Mult.Postion('Second'));
end;
