     *You* used the word "stipulating" above.

     Perhaps, you have missed the point.  I am learning JavaScript.
Note the word "learning".  That means that I do not know as much about
it as I would like.  I have been entering code from a text and working
with it.  If I already understand the code, there is little or no
point to entering it.  If I do not, then there is from the opportunity
to learn.

     Having entered some code, it might not work due to:

  1) bugs: I have found more than one bug in the code.  I am an
experienced P/A, just not in JavaScript yet.

  2) language/browser/other changes since the text was published: The
copyright is 1999, but it is the best text that I have found so far as
to level of detail, and despite its minor errors, it has not flipped
the bozo bit.

  3) my typos: These can be nasty.

     It is hardly futile.  I do get it debugged, and at this point, I
also learn more about the language.  Among other things, knowing
language failure patterns is useful in debugging.

     Sure.

     How fatuous!  That is exactly what I am doing.  However, I am at
the point where some of these exercises are not short bits of code.
Some of them depend on the interaction of many bits.  Besides, it is
not enough to be able to handle small bits of code; I need to be able
to handle larger aggregations of code.

Sincerely,

Gene Wirchenko
