Uhh, of course.  I often use a 'result' variable in functions that
return something so that I can run the debugger over it and press F11 on
it to see the contents.  Pressing F11 on %eof(example) produces an
error, as does eval %eof(example).

I should remove the unnecessary 'if' statement:

      p read_example    b

      d read_example    pi              n

      d result          s               n
       /free
          read example;
          result = not %eof(example);
          return result;
       /end-free
      p                 e
