Advanced Expression Features
There are two types of expressions supported by the Lemur: Variables and Functions. In
previous chapters we defined variable expressions that belonged to Lemur objects. In this
chapter we introduce the concept of global variables as well as global user-defined
functions. These expressions can be accessed from any Lemur object. Finally, we look at
a special global variable built into the Lemur called time that you can use to create
automated and repetitive behaviors in your Lemur configurations.

Available Built-in Functions and Operators
When constructing an expression, you can make use of a number of built-in operators and
mathematical functions. Here is a list:
mathematical functions. Here is a list:
Syntax

Local and Global Variables
Variables listed under a Lemur object are local variables. The MultiSlider object named
Env below has its built-in variable x followed by three expressions serving as local
variables, Dewey, Huey, and Louie.
