Run-Time Library Extensions delivers the following libraries and
utilities to support existing programs:
- Common Debug Architecture (CDA) Libraries
- Introduced in z/OS® V1R5,
CDA provides a consistent format for debug information on z/OS. The CDA Libraries provide
a set of APIs to access this information.
- c89 Utility
- This utility compiles, assembles, and binds z/OS UNIX System
Services C/C++ and assembler applications.
- UNIX System Laboratories
(USL) Libraries
- The USL I/O Stream Library provides the standard input and output
capabilities for C++. The USL Complex Mathematics Library provides
the facilities to manipulate complex numbers and to perform standard
mathematical operations
Note: The UNIX System
Laboratories (USL) I/O Stream Library and Complex Mathematics Library
are still supported on z/OS.
Although support for these classes is not being removed at this time,
it is recommended that you migrate to the Standard C++ iostream and
complex classes. This is especially important if you are migrating
other USL streaming classes to Standard C++ Library streaming classes,
because combining USL and Standard C++ Library streams in one application
is not recommended. For more information about the Standard C++ I/O
Stream Library, see
Standard C++ Library Reference.
