C/C++ IBM Open Class® Library: As previously announced in Software Announcement 203-131, dated May 13, 2003, the application development support (that is, the head- ers, source, sidedecks, objects, and samples from the Application Support Class and Collection Class libraries) is withdrawn from the C/C++ IBM Open Class Library (IOC) in z/OS 1.5. Applications that use these IOC libraries cannot be compiled nor linked using z/OS 1.5. Run-time support for the execution of existing applications that use IOC libraries is provided with z/OS 1.5, but is planned to be removed in a future release.
z/OS 64-bit C/C++ environment: z/OS 1.6 delivers the capability to exploit 64-bit virtual in developing and deploying new applications that require a signifi cantly larger addressability of data. This capability is provided with enhanced UNIX System Services, 64-bit Language Environment (LE) run-time developed with the C/C++ com- piler 64-bit support, and the Program Management Binder 64-bit support. The availability of this support completes the major steps of the z/OS 64-bit virtual roadmap.
Java
SDK for z/OS, Java 2 Technology Edition, 1.4 provides a full-function Software Development Kit (SDK) at the Java 2 technology level, compliant with the Sun SDK 1.4 APIs. With SDK for z/OS, Java 2 Technology Edition, V1.4, cus- tomers can:
•Test and deploy Java applications at the Java 2 SDK 1.4 API level
•Continue the “write once, run anywhere” Java paradigm at the Java 2 API level
•Take advantage of the new Java 2 function, including XML and Web services
•Continue to take advantage of:
–Common cross platform programming Security APIs within Java framework
–Java Record Input/Output (JRIO) APIs to provide record-oriented access to VSAM datasets, System catalogs, and PDS directory
–Persistent reusable JVM technology for CICS, IMS, and DB2
•Leverage traditional zSeries software and server ben- efi ts: scalability, reliability, availability, performance and serviceability
IBM 64-bit SDK for z/OS, Java 2 Technology Edition, 1.4 (5655-I56) provides a full-function Software Development Kit (SDK) at the Java 2 technology level, compliant with the Sun SDK 1.4 APIs. With 64-bit SDK for z/OS, Java 2 Tech- nology Edition 1.4, you can run Java applications that were previously storage constrained.
The Java SDK for z/OS is available via download from the IBM ^zSeries Java Web site and by tape from IBM Software Delivery and Fulfi llment (SDF) in SMP/E format.

Unicode
z/OS provides Unicode Callable System Services – code page and case conversions from EBCDIC to Unicode:
•DB2 V7 is the fi rst exploiter
•New hardware instruction on zSeries servers has been implemented to provide superior performance
•Unicode Normalization Services allows programmers to decompose or compose characters from another code page and can apply normalization forms to have the same meaning.
