For the original "newbie" poster:
For newbies, or less expert users like me, it's easy to think that
something like
AppendTo[list, expr]
is a "command" that will do what it says: append expr to list. Takes a
few bad experiences to realize that you actually have to say
list = AppendTo[list,expr]
Same general principle applies more broadly.
