What I was thinking is that you can pass false for theXValue/ 
theYValue if you wanted the function to act as if those parameters  
weren't passed.  Passing empty would mean you passed in an empty  
value.  With Rev you have to pass a variable as the parameter when  
passing by reference.  Looking at your first post it doesn't even  
look like the get code

get PDFGetXY(theDocumentRef,empty, empty)

would execute without an error.  Does it work on your end?
