Siemens Logo Programing in LAD

Hi
This is probably something simple, but I can't work it out.

I'm doing some Logo programing in LAD and I can't seem to add anymore lines of program or make the page bigger?
I have 16 lines (counted on the grid)

Thanks in advance

Hi. You can choose how many pages you want by "Page Layout"

This also works when you programme in Function-blocks
