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 Mult := TMult.Create(Form1); {Create Mult. Make Form1 its owner} Label1.Caption := 'The position of the ''Third'' element is ' + IntToStr(Mult.Postion('Third')); {will be -1 since the list is empty} Mult['Second'] := 'Two'; Label1.Caption := 'The position of the ''Third'' element is ' + IntToStr(Mult.Postion('Third')); {will be -1 since 'Third' item does not exit} Label1.Caption := 'The position of the ''Second'' element is ' + IntToStr(Mult.Postion('Second')); {will be 0, TMult positions start with 0} end;
