I'm not familiar with the Collapse method, so I'm not sure if there's something more to what you want to do.
If you just want to start Word, create a new document and set it to be centered and set the font and size and type in some stuff, the following will do it (I got the Selection object from a recorded macro and merged it into the code you posted):
#DEFINE wdalignparagraphcenter 1
oword=CREATEOBJECT('word.application')
oword.VISIBLE=.T.
odoc=oword.documents.ADD()
orange=oword.selection
WITH orange
.paragraphformat.ALIGNMENT = wdalignparagraphcenter
.FONT.SIZE = 14
.FONT.NAME = ("Arial Black")
.typetext("Some text to put on screen")
ENDWITH
