  • S508 - How to migrate to the new generation of COBOL compilers, COBOL compiler migration has changed!

    General Interest Sessions: Charlie

    Session Evaluation

    New and improved IBM recommendations and tools for migrating to Enterprise COBOL V5 and COBOL V6 will be discussed!

    The new COBOL compiler offers many features for programmers and applications managers, but it also takes some work to get to use it.  In this session, the speaker will tell you everything you need to know to get up and running with Enterprise COBOL V5 and V6.  We will talk about what has changed, what is better, and what you will have to change in order to use the new compiler. There may be source code changes, there may be input data changes, or you may use new options to tolerate invalid COBOL data.  Compiler options have changed, some behaviors have changed, some new restrictions have been added, and performance has changed, come and hear all about it!

     

  • S610 - What's New in the Latest COBOL compiler for z15, COBOL V6.3!

    Application Development Session: Alpha

    Session Evaluation

    IBM Enterprise COBOL for z/OS®, V6.3 supports the following features and enhancements:

        - Support for creating AMODE 64 ( "64-bit" ) batch applications

        - Improved efficiency in processing of UTF-8 data by supporting the UTF-8 data type

        - Numerous additional features and enhancements from the COBOL 2002 and 2014 Standards

        - With the new ARCH(13) compiler option, the compiler generates application code that exploits

           instructions available with the latest z15 server. Specifying ARCH(13) instructs the compiler to include

           exploitation of the Vector Packed Decimal Enhancement Facility, which translates into improvements in

           COBOL computational performance. You can recompile with ARCH(13) to target z15 without any source

            changes to take advantage of this new facility.     

        - Compiler and runtime support for the IBM z/OS V2.4 operating system so applications can take advantage of the latest operating system features and capabilities

        - Support for the latest middleware, including IBM CICS®, IBM Db2®, and IBM IMS
