Course Overview
The IBM Z/OS REXX Programming Workshop is an intermediate-level course designed for professionals who need to write and maintain REXX programs within the z/OS environment. It targets systems programmers, mainframe application developers, and automation engineers responsible for enhancing operational efficiency on IBM mainframes. While there is no direct certification exam tied exclusively to this course, it supports mastery of skills required for broader IBM z/OS certification paths such as the IBM Certified Specialist – z/OS Application Developer. With over 70% of Fortune 500 companies still relying on IBM mainframes for critical transaction processing, expertise in REXX programming remains in demand for maintaining and automating legacy systems. Participants should already possess foundational knowledge of z/OS, including TSO/E, JCL, and basic programming concepts, which can be obtained through prerequisites like the Fundamental System Skills in z/OS (ES10G) course.
This hands-on workshop covers key technologies including TSO/E REXX extensions, MVS console command interaction, batch execution via JCL, and the use of the REXX compiler. Students engage in extensive lab exercises using a live z/OS environment, where they build functional REXX execs that read and write data sets, parse complex input using the PARSE instruction, manage compound variables, and handle errors using SIGNAL ON conditions. A core component of the training involves configuring REXX programs to execute host commands and interact with system services, simulating real-world scenarios such as automated job submission and system monitoring. The labs are conducted in a dedicated z/OS lab environment with full access to ISPF, JCL, and SDSF, enabling learners to gain practical experience in debugging, compiling, and deploying REXX scripts across different z/OS subsystems.
By completing the Z/OS REXX Programming Workshop, participants strengthen their readiness for IBM’s enterprise mainframe certifications and improve their competitiveness in the niche but enduring mainframe job market. Mainframe developers with REXX and z/OS skills report average annual salaries between $90,000 and $120,000 in North America, reflecting the specialized nature of the role. Koenig Solutions enhances this learning path with Guaranteed-to-Run scheduling, official IBM courseware, and options for 1-on-1 instructor-led training, ensuring personalized attention and flexible delivery. Graduates of this program are well-positioned to advance into senior mainframe development, systems automation, or legacy modernization roles within financial services, healthcare, and government sectors that continue to depend on IBM z/OS infrastructure.
What You'll Learn
Prerequisites
- ["Fundamental system skills in z/OS (ES10) or equivalent experience are essential for mastering the IBM Z/OS REXX Programming Workshop. Participants should be able to write basic Job Control Language (JCL) statements, which are crucial for job automation on mainframes. Experience coding in programming languages such as COBOL or PL/I enhances understanding of z/OS environments. The ability to create, modify, and delete data sets using TSO is vital for efficient data management. Familiarity with z/OS system operations and MVS console commands helps in navigating and troubleshooting the system effectively. Additionally, understanding TSO/E and ISPF navigation within z/OS ensures smooth workflow. These prerequisites prepare learners to gain comprehensive skills in Z/OS REXX scripting, enabling them to automate tasks and improve system efficiency. Completing this course can significantly boost your mainframe automation skills, opening new career opportunities in enterprise IT environments. IBM's 2023 statistics show that mainframe skills remain in high demand, with a 15% growth in related job roles worldwide."
