Check Help for OLE Automation. Basically, you can create an object that is an XL application. It is probably good to use a property to hold it, IOW...

this.ExcObj = CreateObject("EXCEL.APPLICATION")
if type('this.ExcObj') <> 'O' 
     && There are differing opinions on the best way to test
     && an object.
endif

with this.ExcObj
	.Application.Visible = .F. 
	.Application.DisplayAlerts = .F. 
	.Workbooks.Add 
endwith

And so on and so forth as it were...
