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is withdrawn from the C/C++ IBM Open Class Library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.

ucts, go to: ibm.com/servers/eserver/zseries/software/

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.
