jfta.demo.cs

This is a simple client/server application. Clients send requests to a tagboard ``request'', and a server processes them and returns them back via a tagboard ``reply'' to the clients. The request is basically to perform a two-argument operation ``+'', ``-'', ``*'', ``/'', and ``Q'' (an invalid operation) on two decimals. The server returns the result or an error in case of an invalid operation (including division by zero).

This example illustrates tight coupling of ensembles and tagboards through synchronization.

It also illustrates the use of the reply() method of actors and tagboards to create HTML output for visualization of actor/tag status.
