How do I use named anchors across frames?

I have following frameset:

B is 0px high so all user sees is A, C and D.

|----------------------------|
||--------------------------||
||               A          ||
||--------------------------||
||               B          ||
||--------------------------||
|----------------------------|
|		|                    |
|		|                    |
|	C	|         D          |
|		|                    |
|		|                    |
|----------------------------|

D is the main frame and holds quite a lot of information,

Rather then split this info into seperate pages I want to put links in 
frame A to named anchors in frame D.

How is this done? I dont't want frame D to be reloaded though.
