I should had done as Michael did ... my two failures are below

   20   ***** test # replace base m-file
   21  echo_to_file ('function a=dispatch_x(a)', "dispatch_x.m");
   22  dispatch('dispatch_x','length','string')
   23  assert(dispatch_x(3),3)
   24  assert(dispatch_x("a"),1)
   25  sleep (2);
   26  echo_to_file ('function a=dispatch_x(a),++a;', "dispatch_x.m");
   27  rehash();
   28  assert(dispatch_x(3),4)
   29  assert(dispatch_x("a"),1)
   30 !!!!! test failed
   31 `dispatch_x' undefined near line 5 column 9  ***** test #  
replace dispatch m-file
   32  echo_to_file ('function a=dispatch_y(a)', "dispatch_y.m");
   33  dispatch('hello','dispatch_y','complex scalar')
   34  assert(hello(3i),3i)
   35  sleep (2);
   36  echo_to_file ('function a=dispatch_y(a),++a;', "dispatch_y.m");

   38  assert(hello(3i),1+3i)
