That's a common pattern, yes. Your example doesn't contradict my
point, though: because [line-seq] can't access the parent $0 *),
you have to pass it from the outside.</p>

Please don't. $0 are potentially different every time you open the
abstraction. Currently, they start with 1000 and increment
monotonically, but this is really an implementation detail that
you shouldn't rely upon.<br>

$0 is a unique number that only the abstraction itself knows
about. Typically you use it to keep things local. Just like you
can't send a message to [r $0_msg] from another patch, you can't
do it with "-send", either.
<p>Just create a new patch, put your abstraction there and add a
[receive foo] (without $0!) that will send the appropriate
message to the abstraction. Now you can do</p>
<pre>$ pd -nogui -send "foo 1"</pre>
