Dynamically referencing components through an incrementing variable

With one of my Delphi programs, I have many components named 'last1'...'last26' and 'new1'...'new26' all on a single form. I would like to reference each of these objects through an incrementing variable. EG: if the incrementing variable was called x, I would like to do something of the following:
  while x < 27 do
    begin
      form1.last(x).caption := ('Last', + x);
      x := x + 1;
    end;

Where x is repeatedly incremented until it reaches the value of 26 etc...
Is this possible in Delphi?

Use findcomponent like this

MyComponent : TComponent;

MyComponent := FindComponent('last'+inttostr(CompNum));

May be that should be:

    MyComponent : TComponent;

    MyComponent := FindComponent('last'+inttostr(x));

To remove any confusion with compnum...

Raymond is right....The full code..

For x := 1 to 26 do
  TButton(FindComponent('last' + IntToStr(x))).Caption := 'last' + IntToStr(x);

That's an example...

Cheers,
Viktor
