This document covers the following topics:
This section provides the programmer with reference material on the RPC Communication Area. The RPC communication area is used to specify parameters which are needed to communicate with the broker and are not specific to interface objects. These are, for example, the broker ID, client parameters such as user ID, password and the server address such as class/servername/service etc.
The RPC communication area is provided in include file RPCCOM.

Name of the field in the RPC communication area.
Explanation of the purpose of the field.
Indicates for input fields whether they have to be given by the RPC application (required) or may be given (optional). Fields marked with Auto are managed internally by the interface objects and the Using the Generic RPC Services Module themselves.
Indicates whether the field is an input field (to be given by the RPC application), or an output field (returned to your RPC application).
Notes:
COM_DATA_SCHUNK whereby the needed number is adjusted automatically by
the interface object then. With the field COM_DATA_NCHUNK a minimum number of
blocks allocated is defined, which is used if the calculation by the interface
object gives a lower number than the minimum. The default minimum number (4
blocks) can be altered with the field COM_DATA_NCHUNK. Normally it is not
required to alter COM_DATA_SCHUNK and COM_DATA_NCHUNK fields.
