With the newly released Open XL C/C++ 2.2 compiler, IBM reaffirms the commitment on combining the benefits and innovation from open-source Clang and LLVM technology framework with the leading-edge compiler technology and modern z/Architecture from IBM to deliver a best of breed C/C++ compiler. This enables application modernization on z/OS not only for C/C++ applications but also for building components for open enterprise languages such as Python, GO, Node.js, and Java, to address IT and business requirements in a hybrid-cloud environment.

As shown in the C/C++ compilers on z/OS roadmap below, the Open XL C/C++ 2.2 for z/OS with the newly added z/OS subsystems support for CICS & IMS and debugging improvements is a step closer to fill the functional gaps with z/OS XL C/C++. IBM is committed to continue enhancing Open XL C/C++ for z/OS with new features such as Db2/SQL subsystem support, enhanced debugging, and Metal C to meet customer demands.

Additionally, to provide more information regarding the withdrawal announcement of IBM Enterprise Metal C for z/OS 3.1.0 (5655-MCE) which is a standalone Metal C product, IBM continues to provide Metal C support with XL C/C++ as a priced-feature of z/OS and intends to add Metal C support in a future Open XL C/C++ release.
