For more information, see:
- Assembler macro support
z/OS Language Environment provides a new assembler macro, CEEGLOB. Support is added for the RMODE and AMODE keywords on the CEEENTRY macro. Support is added to the CEEFETCH macro to handle non-Language Environment routines. Support is added for the SERVICE keyword on the CEEPPA macro.
For more information, see:
- CICS additional floating-point support
Language Environment, in conjunction with CICS Transaction Server for z/OS, Version 4, is designed to support IEEE binary floating-point (BFP) and IEEE decimal floating-point (DFP) in applications run under the Language Environment-CICS extended run-time language interface (ERTLI).
For more information, see the CICS chapter in:
- AMODE 64 enhancements
- Support for GETSTORE, FREESTORE, and MSGRTN
z/OS Language Environment provides support in CELQPIPI for the GETSTORE, FREESTORE, and MSGRTN service routines similar to those routines in CEEPIPI.
For more information, see:
- Large Page Support
Language Environment provides support in __moservices() for allocating memory objects that are to be backed with large page frames.

Language Environment, in conjunction with z/OS UNIX System Services, provides a new signal, SIGTRACE, that can be used to start and stop the syscall trace.
For more information, see:
- Heap pools
Language Environment provides LEDATA formatting of heap pools information. In addition, the heap pools trace capability is enhanced.
For more information, see:
- File I/O tracing
Language Environment provides a stream I/O tracing mechanism within the C/C++ run-time library.

Language Environment, in conjunction with z/OS UNIX System Services, provides a new option for umount() that supports a remount (unmount and mount) in the same mode.
For more information, see:
- Asynchronous I/O support
Updates are made to the C/C++ run-time header file to support an asynchronous I/O form of accept_and_recv(). This support is in conjunction with z/OS UNIX System Services.
For more information, see:
- I/O support for extended address volumes (EAVs)
Language Environment provides I/O support within the C/C++ run-time library for extended format sequential data sets residing in the extended addressing space on extended address volumes (EAVs).
