Re: Is this the Free-Format that we asked for?

I really don't see why you find these hard to follow.   Yes, for someone
still in school learning this stuff, its a bit confusing.  But after
working with it for a few days, its second nature.

I've wanted MANY TIMES to be able to do something like a=b=c=0.

Something like A = (B = C) is basically just a COMP op-code, except that
you can give a more meaningful name to the result than "57".  

Personally, I like languages (like C) that use a different operator for
comparisons vs. assignments.  If you know that = is an assignment, and ==
is a comparison, your examples are pretty easy.

must be assigning 0 to everything, since = is only assignment:
a = b = c = 0

must be assigning a boolean value to a, since == is a comparison:
a = (b == c)

etc
