     I disagree with the part I set apart in "=======".  It's not hard if
the grader is paying attention while grading.  I generally had 40-60 programs
to grade at a time.  Especially if the changes to the student's programs
are as simple as you state.  I remember the flow of the code, not the
identifier names.
     Even rearranging subroutines into a different order isn't hard to catch.
(Though with our Cyber line-editor, moving around subroutines in a file was
almost good enough for a Ph.D. Thesis, so we didn't see that much.)
     I guess it all comes down to whether you're skimming the code or studying
it.  I grade using the latter.  You can tell a lot more about how much work
the student did by studying the code than by studying the output.
