A method for dispatching steps of an application running on an application server which can be accessed from client terminals. Users select user interaction elements on client terminals, and the interactions are transmitted to the application server executing a main part of an application, which creates output that contains the next set of possible user interactions. Calling application steps can be addressed and invoked by other application steps in order to reuse software components necessary for processing said other application steps. Nesting programming commands used to call another application step are arbitrarily nested and serve as a called sub-routine within the calling application step. Values are returned to the calling application step, and nesting paths of called application steps are discarded in case a user switches to another application.
