 In the body of the member function \tcode{tnode::set}, the member names
 \tcode{tword}, \tcode{count}, \tcode{left}, and \tcode{right} refer to
 members of the object for which the function is called. Thus, in the
-call \tcode{n1.set("abc",\&n2,0)}, \tcode{tword} refers to
-\tcode{n1.tword}, and in the call \tcode{n2.set("def",0,0)}, it refers
+call \tcode{n1.set("abc", \&n2, 0)}, \tcode{tword} refers to
+\tcode{n1.tword}, and in the call \tcode{n2.set("def", 0, 0)}, it refers
 to \tcode{n2.tword}. The functions \tcode{strlen}, \tcode{perror}, and
 \tcode{strcpy} are not members of the class \tcode{tnode} and should be
 declared elsewhere.\footnote{See, for example, \tcode{<cstring>}~(\ref{c.strings}).}
