Now according to VFP Documentation AND Tamar Ganor's book MS Office Automation With VFP, I should be able to use the GetObject() function to either create an instance of Word if needed or if Word is already started, simply open the document. I have tried the following with the same assignment as above to lcDocument:

Elgin,

oWord = GetObject(, "Word.Application")
oWord.Documnts.Open(lcDoc)

Basically either creates a new instance or gets one existing if any. BUT never do it IMO. When you need one use createobject() or if you're keen about you want one only at least do it like :

if isnull(oApp.oWord)
oApp.oWord = createobject("Word.Application")
endif

My 0.2 cents.
