In an OpenROAD client, the complexities of driving the COM interface are hidden within a 4GL system class, RemoteServer. The RemoteServer system class lets you invoke procedures on an active OpenROAD Server by providing a required procedure name and optional parameters. When the procedure is complete, you can view the status returned.

This simple way of accessing the OpenROAD Server is unique to 4GL clients and consistent with the productivity benefits available when using 4GL in general. It is the backbone for building multi-tier OpenROAD applications.
