IBM Debug for z/OS® offers debugging and code coverage for z/OS applications written in COBOL, PL/I, C/C++ and Assembler. 

IBM Debug for z/OS, the traditional z/OS debugging product, is powered by the IBM z/OS Debugger and provides a 3270 user interface and remote debugging through Eclipse. Additional z/OS Debugger capabilities and client options are available in IBM Developer for z/OS, and IBM Developer for z/OS Enterprise Edition.

Features

• **Deep and wide z/OS environment support: **Provides extensive subsystem support including environments such as Batch, CICS®, IMS, Db2®, z/OS Unix and TSO -- for day one support of the latest hardware, compilers, z/OS, CICS, IMS, Db2 and batch. This includes the ability to debug 64 bit applications and modules optimized with IBM Automatic Binary Optimizer for z/OS.
• **Code coverage to measure testing. **Offers both client initiated and automated (headless) code coverage collection and the ability to view and combine code coverage results.
• **Valuable data at your fingertips: **Monitor variables, registers, memory and expressions.
• **Extensive debugging options: **Set breakpoints at statements, programs and conditions, run until a breakpoint is reached, view and change the values of variables and storage and much more. Supports shift-left testing initiatives - Measure the effectiveness of your automated testing by using code coverage in conjunction with IBM Z Virtual Test Platform or the ZUnit capability of IBM Developer for z/OS. - Simplify system test activities with IBM Debug for z/OS or IBM Developer for z/OS Enterprise Edition used in conjunction with the Rational Integration Tester beta to enable virtualization of Db2 calls.
• Boost your debug experience - For debugging using a traditional 3270 user interface, use IBM Debug for z/OS or IBM Developer for z/OS Enterprise Edition. - Visual debug, available through IBM Developer for z/OS, IBM Developer for z/OS Enterprise Edition, or IBM Wazi Developer, provides a graphical view of program execution flow, including the current execution path, plus features like setting breakpoints from the source editor. This extends the basic debugging with Eclipse IDE offered by IBM Debug for z/OS.

Benefits

• **Accelerate everyday developer tasks: **Enable developers to examine, monitor, and control the execution of programs in context while testing and debugging.
• **Optimize testing: **Use code coverage combined with code coverage results to optimize your testing resources.
• **Simplify debugging: **Ease grasp of complex z/OS applications with visual debug.
