Think.  To test my assembler, I hand assemble something, then run it through
the assembler and then compare the two results.  What your saying is that my 
assembler is then useless because I can do it by hand, untrue.

Not if they are owned by the professor.

As a computer engineering student, I see rampant cheating in lower computer
classes, I've worked in a computer lab and have had people come up to me and
ask me how to doctor results.  It doesn't go up to the higher classes, 
because if you can get 99% of an assembler working the last 1% isn't 
terribly hard.

In my opinion: (a) the problem needs to be recognized.  (b) solutions to
the problem need to be found.

BTW, lets move this discussion away from net.unix.
