2.4.1 is more than a slight update, it’s a completely different front-end. To make it more confusing there are three C/C++ compiler products on z/OS.
XL C/C++ is the legacy compiler which supports 31/64-bit and has CICS translation built it. It can run as a batch program. IBM have made no statements of direction but it’s withering on the vine and does not support the latest C/C++ standards. It’s almost impossible to use it for any modern ports. I can’t see this product ever disappearing as it’s required for the old school JCL only shops. That’s not a dig at Peter, we have products that use PDS data sets and are compiled using a legacy SCM product. I find it very difficult to adapt when I work on these products after spending so long building in a shell. XL C/C++ 2.4.1 Web Deliverable is a port of Clang which uses the existing back-end. It’s better than the legacy compiler but it must run as a z/OS UNIX executable. It supports more modern language standards such as C++14. Open XL C/C++ is a full on port of Clang. IBM are working with the open source community. It’s interesting to read the code reviews which include devs from Apple and Google. It’s my understanding that this compiler will replace 2.4.1 some time in the future. > On 9 May 2023, at 12:29 pm, Phil Smith III <li...@akphs.com> wrote: > > David Crayford wrote: > >> They're different products.
