EZ-Script is the native programming language for the EZ-Builder Robot Control Software. Every control within EZ-Builder has a configure button with a gear icon. When the configure button is pressed, a dialog will be displayed with a number of configuration options pertaining to the control. Many of the controls will have functions and parameters which can be assigned EZ-Script. For example, pressing the A button on the WiiMote can be assigned EZ-Script.
The EZ-Script manual of functions and commands can be found within the EZ-Builder Software. If you're looking for a hard copy of the EZ-Script manual, you can Print or Save the EZ-Script manual.
