For z/OS Version 1 Release 3, Language Environment provides the following:
- z/OS.e
z/OS.e is a version of the z/OS operating system intended to help you exploit the fast-growing world of next-generation workloads. Language Environment adds new messages that may be issued when errors occur in the z/OS.e environment.
Restrictions: The following restrictions apply to z/OS.e:
- The following compilers are not licensed for use on z/OS.e:
- The following subsystems are not licensed for use on z/OS.e:
- Execution of applications written in the following languages is not functionally supported on z/OS.e:
- COBOL (except for precompiled COBOL DB2 stored procedures and other precompiled COBOL applications using the Language Environment preinitialization interface
- FORTRAN
- The following are not functional and/or not licensed for use on z/OS.e:
- Language Environment Library Routine Retention (LRR)
- Language Environment compatibility preinitialization for C and PL/I
- Run-time library services (RTLS)
- Customers are not permitted to use lower levels of Language Environment on z/OS.e.
Customers will be able to run pre-compiled PL/I programs in z/OS.e. They will not be able to compile PL/I programs in z/OS.e.
- z/OS Managed System Infrastructure for Setup
z/OS msys for Setup provides a set of functions and services to simplify system management. Specifically for Language Environment in z/OS Version 1 Release 3, setup is simplified for:
- BATCH and CICS default options settings, by customizing a ++USERMOD.
- Region-wide run-time options for CICS and IMS, by running an Assembler job.
- BiDi layout transformation function and utility
As an extension to the BiDi layout services provided in z/OS Version 1 Release 2, this provides C/C++ support to perform code page conversion or BiDi layout transformation of a text string in one step. For more information, see z/OS C/C++ Programming Guide.
- Access Control List (ACL) support
ACL support provides security support for z/OS UNIX users.
- OMVS outage avoidance
OMVS outage avoidance provides the capability to IPL z/OS UNIX without bringing down the z/OS system, which allows for more timely debugging of z/OS UNIX.
- Language Environment preinitialization services (CEEPIPI)
Enhancements have been made to Language Environment preinitialization services (CEEPIPI) to support XPLINK.
- Vendor heap manager
This enables vendors to provide an alternate user heap manager for z/OS UNIX applications that can detect memory leaks or storage damage beyond what is already provided in Language Environment.
- Thread-specific data performance enhancements
This optimizes the C/C++ pthread_getspecific() function to obtain peak performance in the z/OS UNIX environment.
- Euro code page support
Support is extended for code pages currently supported within z/OS that have not yet been updated for Euro symbol support.
