Yes, you can do that. FYI, it's called threading in traditional
programming languages and is often a pain in the ass, but since chuck
isn't a traditional language it's called sporking and is as simple as
running a chuck file.

I don't know how you create your patches and run them on your system,
but I am a command-line person, so when I start coding in chuck, I open
a command-line and type "chuck --loop". Then I open another command-line
and create/dig out my patch and I run it with "chuck + patch.ck".

Notice how the first command-line with chuck --loop tells us that we
have added a file? Good.

Now I'll create another patch with the second while-loop. I add it to
the virtual machine (the chuck --loop) with another "chuck + patch2.ck".

If you already got both of them done, you can play them synced with the
command "chuck patch.ck patch2.ck"

You can also do sporking in the code, but I haven't looked at that
enough - it's in the help pages, though.

Hope that helps,

ps. look at the on-the-fly-commands.
