This variable determines the size of the low-level receive buffer for a socket connection. For the value to have an affect, it must be set before any sockets have been created. The default value is 16384. The default value should be sufficient for most cases. The receive-buffer-size is passed directly to a call to setsockopt.

Note: The value of this variable is sent to a lower-level socket layer not controlled by ACUCOBOL-GT. It may not have any noticeable effect. Changes in this value are not seen in response to a U debugger command listing the memory usage of the runtime.
