Description of Function pb_display

The pb_display function takes an argument entry, which is a phone book entry. After displaying a horizontal line, pb_display calls MATLAB function strtok to extract the first line the entry, up to the line delimiter (^), into t and and the remainder into r. Then, within a while loop that terminates when t is empty, it displays the current line in t. Then it calls strtok to extract the next line from r, into t. When all lines have been displayed, pb_display indicates the end of the entry by displaying another horizontal line.

• function pb_display(entry)
  disp ' '
  disp '-------------------------'
  [t,r] = strtok(entry,'^');
  while ~isempty(t)
     disp(sprintf(' %s',t));
     [t,r] = strtok(r,'^');
  end;
  disp '-------------------------'
