The IBM Assembler Language Coding Workshop (ES34G) is a comprehensive 5-day course designed for application programmers and beginning system programmers responsible for writing, maintaining, or debugging programs in S/370 or S/390 Assembler Language. This hands-on lab course equips learners with essential skills to develop and troubleshoot mainframe applications, focusing on problem resolution through program check interruption analysis and dump reading. Targeted at roles such as Mainframe Developer, Systems Programmer, and Application Support Analyst, the course addresses a critical industry need: according to the 2024 Futurum Group Global Mainframe Skills Report, 91% of organizations plan to hire mainframe developers within the next two years, underscoring the sustained demand for low-level programming expertise on the IBM Z platform.
Participants in the IBM Assembler Language Coding Workshop (ES34G) engage with core mainframe technologies including z/OS, High-Level Assembler (HLASM), Program Status Word (PSW), Instruction Length Code (ILC), and standard macros like CALL, SAVE, and RETURN. The course features a classroom-based hands-on lab environment where students build and debug real assembler programs using instructions such as LA, LR, MVC, and CSECT, while practicing data definitions for binary, packed decimal, and character formats. A key component involves analyzing formatted system dumps to identify program interruptions, simulating real-world debugging scenarios. Learners complete structured exercises including 80/80 listings, binary data manipulation, text handling, and packed decimal editing, all within an official IBM z/OS lab environment that mirrors enterprise mainframe operations.
While the IBM Assembler Language Coding Workshop (ES34G) does not map to a formal certification exam, it prepares professionals for advanced roles in mainframe system programming and qualifies them for IBM digital badges that validate their expertise. Mastery of Assembler is a high-value skill, often complementing COBOL roles that command average salaries exceeding $120,000 annually, according to Dice.com job market data. Koenig Solutions enhances this training with Guaranteed-to-Run scheduling and official IBM courseware, ensuring consistent access to expert-led instruction. Graduates of the ES34G course are positioned to support critical financial, government, and enterprise systems, driving long-term career growth in the enduring and modernizing mainframe ecosystem.
