well, you in the sample code you provided, you already have global 
variables. (you might want to declare them static too).
to make local variables put them into the "obj1" struct.

oh, i forgot that...

<code>
obj1_class = class_new(gensym("obj1"), (t_newmethod)obj1_new, 0,
</code>

the "0" argument after the constructor is really a pointer to the 
destructor.
so you have to write your destructor function:

void obj1_free(t_obj1*x){
  /* Doh.... */
}

and then do
obj1_class = class_new(gensym("obj1"), (t_newmethod)obj1_new, 
(t_method)obj1_free, ...


and you really should declare all functions (but the setup()!) as 
"static" unless you have reasons to not do so...
