Anyone Experience with XMPie?

I need some help with some Qlingo code for XMPie. I'm trying to do some conditionals.

I'm running XMPie uDirect in InDesign CS5.

I think all I really need to know is the command for a hard return with Qlingo. I'm basically wanting to make XMPie insert a hard return if data is present in a certain field and do nothing if there isn't any data.

Anyone think they can help?

Thanks!
