When you work with a collection in an ActiveX component using RDMLX you must use the RDMLX item keyword. For example, the Word VBA statement to activate a document:

     Documents("test.doc").activate

Becomes in RDMLX:

     invoke method(#wordapp.documents.item<'test.doc'>.activate)

Note also that instead of:

• Parenthesis for the item in the collection you use the greater than and less than signs <>.
• Double-quotes you use single quotes.
