MRG Messaging C++ components now include support for Message Selectors. Other languages had support for selectors, but C++ was missing this. Customers required this functionality in the product. Selector support is now available in the 0-10 and 1-0 protocols for the C++ messaging client and broker code, and implements the selector language with some limitations. This feature is documented in the "Select Messages Using a Filter" section of the Messaging Programming Reference Guide.
