In AskiaScript 2.0, all variables have an implicit type. As with most programming languages, AskiaScript provides Basic variable types (String, Number, Boolean...) and Advanced variable types (Question, Response, Interview, Quota, etc.).
It is not necessary to explicitly indicate the type of the variable; this is done automatically for the question variables, system objects and dynamically for declarative variables (taking the type of the first assigned value).
