How to add a new page after the last page in a Quark 6.1 doc

I am trying to update a script that I used in Quark 4.11. I need to add a page at the end of the document. The code I used before was this:

make new page at end with properties {master document: “Blank Single”}

Quark 6.1 doesn’t understand this. How do I make a new page in Quark 6.1?

try this:
make new page at end with properties {master spread: “Blank Single”}

That did the trick. Thanks! Karen
