Word 3 of
    abc def "xyz"
is
    "xyz"
not
    xyz

The business about "enclosed in double quotes" refers to the (to my  
mind) puzzling convention in RC, dating back to the old HC days, of  
considering anything in double quotes to be one word. So, word 3 of
    abc def "ghi jklmno"
is
    "ghi jklmno"
(with the quotes included). There was a debate about the merits of  
this convention a while back -- search the archives.

But you might have wholematches set to true.

If you do:
    put "abc def ghi" && quote & "xyz" & quote into tSentence
    put "xyz" into tWord
    put s & cr & wordoffset(tWord, tSentence)
then you get
    abc def ghi "xyz"
    4
unless the wholematches = true, in which case the wordoffset returns 0.
