Of course, the experienced TP programer would have written:

t:=root;
while t<>nil do
  begin
    write(t^.str);
    t:=t^.next;
end;

(if root=nil, the repeat loop crashes, someone was sleeping the day they
 talked about linked lists in their data structures class)

at least, you could have taken the BEGIN and END out of the repeat loop 
(wouldn't have made an operational difference, but I know how you C 
 programmers like to save keystrokes).
