+When used alone forces the exit from a function. When used with a variable it forces the exit from a function and returns that variable.
+Example (1)
+<pre>
+func void spawnUs () {
+     ai2_spawn(Muro);
+     sleep(200);
+     return;
+     ai2_spawn(Barabas);
+}
+</pre>
+In this example the code <tt>ai2_spawn(Barabas);</tt> is never executed.
+Example (2)
+<pre>
+var int current_char_id=0;
+func int spawnCharacter (string char_name) {
+     ai2_spawn(char_name);
+     current_char_id=current_char_id+1;
+     return current_char;
+     dmsg("Hello.");
+}
+</pre>
+In this example the current_char is returned from the function (notice the int declaration at the begin of function, which declares the type to return). <tt>dmsg("Hello.");</tt> is never executed.
