About the technology
What REXX is
REXX, short for Restructured Extended Executor, is an interpreted scripting language built for readable automation and command processing. It remains important in IBM mainframe environments, where teams use it to control jobs, process data and connect operational tools. The language is also known as IBM REXX in enterprise contexts and is available through implementations such as Regina REXX.
Where it is used
REXX is closely associated with z/OS, VM, VSE and TSO environments, as well as IBM tools such as ISPF and NetView. Companies use it where reliable script execution matters across long-running operational processes.
- Automating mainframe administration and batch workflows
- Processing datasets, reports and operational files
- Extending ISPF panels and TSO procedures
- Supporting NetView automation and system monitoring
Ecosystem and skills
Strong REXX specialists understand both the language and the systems around it. Relevant knowledge can include JCL, COBOL, TSO, ISPF, SDSF, DB2, CICS and z/OS security. For cross-platform work, experience with Unix REXX, shell scripting, APIs, file formats and enterprise scheduling is valuable.
The right approach depends on the implementation in use. IBM REXX conventions, VM environments and Regina REXX can differ in available commands, interfaces and deployment practices, so compatibility should be checked early.
When companies hire experts
Freelance expertise is useful when internal knowledge is limited or a critical mainframe process needs change without disrupting production. Companies often bring in specialists for modernization, migration, incident recovery and documentation of scripts that have become difficult to maintain.
- Refactoring fragile or undocumented REXX automation
- Migrating scripts between mainframe or Unix environments
- Integrating REXX with databases, schedulers or monitoring tools
- Investigating failures in batch and operational workflows
Working with German teams
REXX work in Germany often supports banking, insurance, logistics, manufacturing and public-sector systems that still depend on mainframe operations. Remote collaboration works well for code reviews, analysis and controlled releases, while on-site access may be required for restricted environments or production procedures. Clarify language expectations, access rules and change windows before work begins.
What strong professionals bring
A capable REXX professional writes clear, modular scripts and understands the operational impact of every command. They can trace dependencies across JCL, datasets, queues and system utilities instead of treating a script as an isolated file. They also test error paths, preserve auditability and document assumptions for the team that will maintain the result.
Look for evidence of work in the same runtime and toolchain. Practical questions about rollback, return codes, encoding, authority and scheduling reveal more than familiarity with syntax alone.
Frequently asked questions
Curious about REXX? Here are the answers that come up again and again.
REXX is mainly used to automate commands, process text and data, and control operational workflows. In IBM environments, it commonly supports TSO, ISPF, NetView and VM tasks, while Unix implementations can handle portable scripting and system integration.
REXX is a scripting language, while JCL defines and schedules many batch jobs and COBOL is used for larger compiled business applications. Shell scripting may be a closer alternative on Unix, but REXX is often the better fit for command automation inside IBM mainframe tooling.
A strong REXX specialist may also understand JCL, TSO, ISPF, SDSF, z/OS utilities, DB2, CICS and enterprise scheduling. Knowledge of security permissions, datasets, APIs and source-control practices helps when scripts form part of a wider operational process.
The required depth depends on the assignment. REXX maintenance may need familiarity with the existing scripts and runtime, while migration, production recovery or integration work calls for broader knowledge of z/OS operations, dependencies and release controls.
Yes, REXX analysis, documentation, testing and code review can often be completed remotely with secure access and clear release procedures. On-site work may still be useful when the environment is isolated, access is tightly controlled or teams need direct collaboration during production changes.
Confirm which implementation and runtime are involved, such as IBM REXX on z/OS, VM REXX or Regina REXX. Ask about relevant tooling, access requirements, testing practices and experience with the exact workflow that needs to be changed.
Good REXX work is readable, modular and safe to operate. Review how the specialist handles return codes, input validation, logging, permissions, failure recovery and documentation, then ask for a test plan that reflects real production conditions.
IBM REXX projects often depend on local conventions, system utilities and access policies rather than language syntax alone. Freelancers should clarify the target environment, development workflow, documentation standard, communication language and whether work is remote, on-site or blended.
The average hourly rate of freelancers in Germany who have used REXX in their recent projects is 98 €, which corresponds to a daily rate of about 786 € based on an 8-hour working day.
Of the freelancers in Germany who have used REXX in their recent projects, 47% hold at least a Bachelor's degree and 33% hold at least a Master's degree.
On average, freelancers in Germany who have used REXX in their recent projects have 35 years of professional experience, with a single engagement typically lasting around 2.3 years.
The most common languages among freelancers in Germany who have used REXX in their recent projects are German (100%), English (96%), and French (25%).
