The start statement is used to activate an active agent that is in the init mode.

An Alvis model contains a fixed number of agents. There is no possibility to create or destroy agents dynamically. Active agents that are initially activated are distinguished in the communication diagram – their names are underlined. If an active agent starts in the \emph{init} mode, it is inactive until another agent activates it with the \emph{start} statement.

The start statement is a single-step statement.

start agent_name;
