I need to use Word to print a document with data from a .dbf.

I use the OLE Automation with Word to do this.
I like to use the word document variables to update the information in Word.

I use this commands:

loWord=CREATE('Word.Application')
loWord.ActiveDocument.Variables("MyField").Value=   MyField

But I do not remember how to create the document.variables in Word.
Right now ( on client site) I do not have the VBA documentation.
Any one remembers how to do this?
