How do I choose the Y Page on a GLCD?

I was following a very useful website on GLCD programming which I cant find now...

so Im stuck quite badly. All this time I have been drawing things on GLCD by simply writing onto a selected X page and then the GLCD shifts by itself on the Y page.

But now I need to move the curser to a particular point on the Y page because I dont want the previous data to be deleted on the screen.

Can someone please tell me what I need to do to select a Y address??

Thanks very much, awaiting any response. Perhaps someonce can also kindly give me that link I lost!

Regards.

The model number of the GLCD would help.

Yes kchriste is right model number of the GLCD would help better.

Thanks guys.

I found the site! This is the one:

Inbtroduction to Graphics LCDs

I will try to set the Y page using the info there.

Thanks for the offer to help.

If your working in C then I posted code in this thread that you may find useful.
