IBM Developer for z/OS® (IDz) is a modern, robust toolset for developing and maintaining IBM z/OS applications through the use of DevOps practices. It helps you deliver more, faster, with better quality and greater agility.

Features

• **Modern, simple z/OS development: **Gain advanced features for COBOL, PL/I, REXX, and JCL editors with improved navigation and content assist, with real-time syntax checking and highlighting, hyperlinks for copybooks and JCL Procs, and sequence number support.
• **Advanced debugging of composite z/OS applications: **Exploit the IBM strategic debug component, IBM z/OS Debugger for debugging applications written in COBOL, PL/I, C/C++ and High Level Assembler that connect to a variety of z/OS environments.
• **Advanced application structure and quality analysis tools: **Use application structural analysis, code analysis and code metrics to assist in delivering COBOL and PL/I applications that conform to in-house programming guidelines.
• **Automated unit testing and code coverage: **Automatically generate unit tests with ZUnit to find and fix problems earlier. Then combine unit testing with code coverage analysis to determine the gaps in application testing.
• **IBM Dependency Based Build (available in Enterprise Edition): **Standardize DevOps processes across platforms with Software Configuration Management and Continuous Integration tools such as Git and Jenkins using IBM Dependency Based Build. It provides a modern scripting-language-based automation capability to build traditional z/OS applications that are developed in programming languages such as COBOL and PL/I.
• **Source control, lifecycle management and problem diagnosis integration: **Adopt modern, parallel development practices with built-in integration with Git and IBM Engineering Workflow Management or integrate with legacy library managers like CA Endevor Software Change Manager. Improve problem resolution by combining with IBM Application Performance Analyzer for z/OS, IBM Fault Analyzer for z/OS and IBM File Manager for z/OS.
• **Gain Microsoft VS Code or Red Hat CodeReady IDE options with Enterprise Edition: **Give z/OS developers the option to choose IBM Wazi Developer for VS Code™ or Wazi Developer for Workspaces as their integrated development environment.
• **Customize and extend the development environment: **Enable developers to modify options to create a customized workspace. The workbench provides documented APIs and tools that allow organizations to extend the out-of-the-box capabilities for features unique to your enterprise.

Benefits

• **Reduce time to value: **IBM z/OS application development tools offer a simple to use, intuitive user interface.
• **Improve the workflow: **A fully integrated debugger provides developers the ability to test, examine, monitor, and control the execution of programs in context.
• **Choose preferred editing style: **Modern editors appeal to new mainframe developers, while ISPF style editors offer navigation that is familiar to traditional mainframe developers.
• **Automate unit testing: **With ZUnit, z/OS developers can easily record, generate and run unit tests to get immediate feedback on their changes.
• **Parallel development. **Integration with Git™ and IBM Engineering Workflow Management.
• **Licensing options. **Developer for z/OS is the base. Enterprise Edition adds Microsoft VS Code and Red Hat CodeReady Workspaces as IDE options, IBM Dependency Based Build, and 3270 debugging capabilities.

Editions

IDz is available in two editions: IBM Developer for z/OS and Developer for z/OS Enterprise Edition. 

• IBM Developer for z/OS, previously known as Rational Developer for z Systems (RDz), provides a range of development tools for COBOL, PL/I, High Level Assembler, REXX, C/C++, JCL, and Java™, all built on an Eclipse base. 
• IBM Developer for z/OS Enterprise Edition enables developers to opt for either Microsoft VS Code or Red Hat® CodeReady Workspaces for their daily z/OS development tasks. The Enterprise Edition is part of the Application Delivery Foundation for z/OS, which includes all the capabilities of Enterprise Edition along with additional problem determination tools, all under one enterprise license.
