I think that the instructor's recommendation was meant so that the
student would gain an appreciation for some of the inner workings of a
computer system.  If a student has worked for a semester with registers,
stacks, memory allocation for variables, etc., he/she will find it much
easier to understand some of the things that go wrong with C programs
(or it just may make the instructor's job easier!).  You may recall the
student program I posted a week or so ago where he had allocated "char"
storage for a variable but used 'scanf("%d", &var)' to get a value.  It
was difficult for me to explain where the extra bytes were going and why
they clobbered the first entry of a "nearby" array of strings.  Had he
had an ASL background, I could have explained it precisely.
