Calls to functions are encapsulated in an URL by the link () function. Parameters are passed as a single array which is more flexible and makes argument changes a lot easier. When the link is called, the arguments' array elements must be fetched with help of the argument getter functions. Argument elements should never start with two underscores because application.class does so for internal data. For more flexibility links can be batched, e.g. you can call a function that creates a record followed by a function which displays the according page.
void defaultview ();
The default page function defaultview() is called if no function was specified (e.g. the application started the first time). User functions must be registered. Any function, also in other classes and outside classes can be specified. Every function (except in derived classes) take a reference to the application.class instance and the argument array.
