HELP! Problems with portrait -> landscape

[jhsu]

I was able to create a new Writer document with the following code:

dim oDesktop as Object
dim sURL as String
dim mNoArgs()
oDesktop = createUnoService("com.sun.star.frame.Desktop")
sURL = "private:factory/swriter"
oDesktop.loadComponentFromURL(sURL, "_blank",0,mNoArgs())

HOW do I convert this document from portrait to landscape? Recording a macro while making the change manually and then saving the resulting code is only enough to get to the Format -> Page -> Page dialog box.

I tried the com.sun.star.style.IsLandscape=True command to no avail.

I can't believe that OpenOffice Basic would not have a way to perform such a basic task. I surely must be overlooking something. Admittedly, it doesn't help that I don't know uno commands.
