Dynamic reference to component name

Hi,  I have a question that is probably quite simple, but beyond my scope of understanding yet.  I have a report that I wish to access a number of QRLabels at runtime.  I would like to loop through that which will be the references for the strings I wish to assign to each QRlabel.caption property.  I don't, however, know how I can dynamically reference a label.  For example,

for x := 0 to PageControl1.PageCount - 1 do;
  begin
    PageControl1.TabIndex := x;
   { y := x + 1;  y was to act as the changing variable for the label}
    frmSchedule.QRlbl_Date1.Caption := 'Week of '+ PageControl1.ActivePage.Caption;
  end;

As you can see, what I would like to change dynamically is the QRlbl_Date1 label to ..Date2, Date3, etc.  The Tab captions are dynamic and can change, so it's not a series of strings that can be hard coded.  Any help would be appreciated.

you can use the findcomponent method.
like this:

for x := 0 to PageControl1.PageCount - 1 do;
  begin
    PageControl1.TabIndex := x;
 with TLabel(FindComponent('QRlbl_Date' + IntToStr(x+1))) do
    Caption := 'Week of '+ PageControl1.ActivePage.Caption;
  end;

hope this helps
