 Casts of primitive types are done with function-style syntax, e.g.
 
     int x = int (123.0);
-    float f = float (getIntegerValue());
+    float f = float (getIntegerValue());

+Arrays of any type can be created in the global scope using C-style syntax.
+Elements of arrays can be set and read from functions.
+Arrays cannot be created within functions or returned from functions.

+For example:

+            foo[i] = i;

 The program communicates with the host computer by using a shared area of memory
 called the heap which the host can change. There are some built-in functions
