//--- ZScript built-in functions and variables ---

//
// Functions and variables other than global functions are properties
// of objects. The syntax for using them is [object name]->[property]
// where "[object name]" is the object's name and "[property]" is the
// property. "Link", "Screen" and "Game" are Link, Screen and Game
// objects that are always available and don't need to be instantiated.

// be an integer. ZScript itself makes no distinction between int and
