    Abstract

    One of the key enhancements available in z/OS V1R6 is 64-bit application development support for C/C++. With 64-bit support, applications can take advantage of the expanded 1 million TB address space. In this IBM Redpaper, we introduce C/C++ programming in a 64-bit environment, examine changes to the z/OS Language Environment, discuss migrating to 64-bit, and consider Java 64-bit programming.

    Table of Contents

    - The z/OS 64-bit programming model

    - Compiling and linking 64-bit programs

    - The 64-bit memory model

    - Changes to the Language Environment

    - ILP32 and LP64 coexistence

    - General C/C++ migration tips

    - Porting Java applications
