14 RDz-based development Common development environment for COBOL, PL/I, C/C++, and Java Simplified development with more information at your fingertips Syntax Check Edit Source Open and edit multiple source and JCL members simultaneously Submit jobs, access job output, or open source members with a single click Statement in error indicated in source Outline view presents COBOL structure Double-Click on the Error Error list in Problems view 14

15 Navigate datasets or jobs live on zos Connect to multiple hosts concurrently Respects existing security configurations and user IDs Search, filter, browse, edit, compare, migrate, and allocate new MVS datasets and USS files Copy source code, members, or datasets between systems with a few mouse clicks. Access JES queues submit jobs, view job state, and open output spools Submit TSO or USS commands Add datasets and members into projects to group applications and work items together logically Open an emulator in the IDE to configured hosts 15

16 Edit and syntax check source code Use advanced editing technology to: Work with multiple source and JCL members concurrently from different systems Execute 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 keywords Ensure 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 compilation Syntax 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 compilers Syntax 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 16

17 Working Offline Allows users to edit files and Syntax checking while disconnected from the host. Detects Conflicts and changes 17
