● Add datasets and members into projects to group applications and work items together logically

● Open an emulator in the IDE to configured hosts


TechWorks

Edit and syntax check source code● Use advanced editing technology to:

Work with multiple source and JCL members concurrently from different systemsExecute ISPF commands in the workstation editor (e.g, FIND, CHANGE, INSERT LINE, etc)Use syntax highlighting and code-completion to gain insight into available variables, verbs, and keywordsEnsure compliant COBOL/PLI syntax with feedback as you type

● Issue syntax check commands against project source code

Syntax check remotely to ensure proper code structure before compilationSyntax check locally ensure proper code structure and save MIPS. RDz will download code and dependencies (e.g., copybooks) to the workstation and compile using local compilersSyntax Errors are listed in the Remote error list. Double-click on the error to open the dataset and focus on the line where the error occurs

Create enterprise services…● Web services provide standardized

access to assets for different software applications residing on disparate platforms

● Web service definitions provide abstract interfaces which allow for loose coupling between business components –implementation can vary without affecting consumers

● You can reuse applications exposed as Web services in a variety of service-oriented architecture frameworks, such as a process choreographer or an enterprise service bus.

RDz improves zOS application developmentModern UI for z/OS developers reduces training costs, more attractive to younger developers

Windows Explorer-like feel simplifies interaction with z/OSPoint and click to allocate, copy, move z/OS files and datasets

Eclipse-based open source IDE increases productivityEnables more relevant information to be readily availableSpecialized editors and code generation wizards speed development

Code assist for COBOL, PL/I, C/C++, Visual editors for BMS and MFS mapsGenerate code from UML

Workstation syntax checking reduces host CPU usageFewer COBOL and PL/I program compiles required on z/OS

Integrated business development language reduces training costs and increases productivity

EGL lowers skill requirements for Web 2.0 development and multiplatform development

Benefits: Productivity, higher quality code, reduced training, MIPS offload** Reference RDz z/OS Traditional Development presentation
