IBM Open Class Library Transition Guide



IBM has standardized on the C++ Standard Library, including the Standard Template Library (STL) and other features of the ISO C++ 1998 Standard, and removed support for the IBM Open Class Library from the latest releases of the C++ compiler products on the z/OS, AIX and iSeries platforms. This change in IBM’s direction has been communicated to customers.

Application owners and customers whose applications depend on the IBM Open Class Library will need to migrate away from using the IBM Open Class Library when developing new applications. The attached document explains the various options available to application owners and users to make this transition as simple as possible.
