The language that E3 Studio uses in its scripts is VBScript, a subset of the Visual Basic language developed by Microsoft. VBScript contains a fast, light, and portable interpreter, developed for use on Internet browsers and other applications using ActiveX Controls, Automation Servers, and Java Applets.
As seen before, scripts are linked to events of an object. However, to facilitate and increase development speed, E3 already incorporated some of the most common actions that can be performed with scripts, through wizards known as Picks. Users can therefore define that a given event either executes a script, a Pick, or a combination of both, in a sequence that is also pre-defined.
Each View in E3 Studio displays at least two tabs on its lower side, Design and Scripts, except for Database and Alarm Server objects, which do not have a Design tab. Objects and their child objects can be manipulated on the Design tab. To manipulate their scripts, use the Scripts tab. The available options on the Scripts tab are described on the next table.
