View source for RAL: Scripts & A Talking Lemon

==Making It Talk==

Now that we have an agent that we want to do stuff to, let’s try actually, well, doing something to it.

<pre>
> rtar 1 2 10 mesg wrt+ targ 126 "Hello! I'm a talking lemon!" hots 0
OK
</pre>

Breaking it down into its' constituent commands, we have:

* <code>rtar 1 2 10</code>: Selects the Speech Bubble Factory, an agent which produces speech bubbles.

* <code>mesg wrt+ targ 126 "Hello! I’m a talking lemon!" hots 0</code>: Sends message 126 "Make Speech Bubble" to the Speech Bubble Factory (as targ), with parameters "Hello, I’m a talking lemon!" (the text) and hots (the speaking agent, in this case whatever’s under the pointer). Important to note is that everything after mesg wrt+ is a valid expression.
