<h1>Description</h1>
<table>

This declares a variable as a constant (a variable whose value will never  change and cannot be changed) and assigns the value to it.

<br />

<br />
Assign constants to values you know will not change in your game (screen width,  height - scoring values - etc). This reduces the load of the variable memory,  since Blitz knows it will never change size unlike other variables which can  grow and shrink in size based on what value it holds.
