Dear JavaScripters:

     The text I am following has a oddball piece of code.  Please
check that I am reading it right.

***** Start of Oddball Code *****
function writeDocument(n,s) {
 var doc=parent.frames[1].frames[n].location = s
}
***** End of Oddball Code *****

     As I read this, the location for a frame will be set to s.  doc,
a local variable, will be set to s as well.  But this is all there is
to the function, and therefore, the
          var doc=
part of the body serves no useful purpose.

     Am I correct in my reading?

     Sometimes, I think that errors like this in a text are horrible;
other times, I think it is good exercise.  I am undecided here.  (I
did not know about JavaScript's multiple assignment, so I suppose that
I have learned something.)

Sincerely,

Gene Wirchenko
