Moving from 3270 ISPF to IBM Developer for z/OS

Experienced ISPF users who move to the IBM® Developer for z/OS® client as a development platform must learn new terminology, new concepts, and new methods to complete tasks. You must also learn how to use different artifacts and know how they relate to each other. Even though the development tools are different, the overall application development work flow is the same.

The typical z/OS development environment includes using Interactive System Productivity Facility (ISPF) and switching between several tools to develop applications in a z/OS environment. The overall process includes these tasks:
  • Edit your source file and save the file.
  • Edit the JCL code that is required to run your job on the z/OS system.
  • Compile your application by submitting it to run on the z/OS system.
  • Monitor and review the job output.
  • If there are errors, edit the source file to make corrections. If there are errors, you must remember where the error is, switch to an editing session to make corrections, and repeat the cycle.
