[PD] send message to [r $0_something] from command line?

[João Pais]

you can send something to $0-xxx variables, but you should only do it if 
it makes sense.

I often create abstractions using $0 as an argument, such as [line-seg 1 
2 $0], and then $3 in the abstraction is the same as $0 in the parent. 
if you really want, you can export the individual $0-values to a text 
file to be read in the command line. But is it necessary?
