COBOL code analysis for the programs that run your business
SMART TS XL reads every COBOL program, copybook and job, maps how they depend on each other, and flags the code that makes change risky. Understand a legacy program in minutes, see the impact of a change before you make it, and modernize with facts instead of guesswork.

SMART TS XL for COBOL code analysis
Using SMART TS XL for COBOL code analysis significantly improves the efficiency and accuracy of managing legacy systems. Its comprehensive impact analysis helps developers understand the intricate relationships and map the dependencies within COBOL programs.
Advanced static analysis identifies potential issues, inefficiencies and vulnerabilities in the code, so problems are resolved before they reach production. Detailed visualizations and robust reporting turn that analysis into clear, actionable insight, so code changes do not introduce new errors or regressions.
By automating much of the analysis, SMART TS XL reduces manual effort and frees teams for higher-value work: faster development cycles, better code quality and stronger system performance. For organizations that rely on COBOL, it is an indispensable tool for maintaining and modernizing critical applications.
Without SMART TS XL
- Copybooks, programs and JCL scattered across libraries
- Changes estimated from memory and the one expert left
- Dead code and GO TO tangles discovered in testing
- Analysis burns expensive mainframe cycles
With SMART TS XL
- Every COBOL asset indexed and cross-referenced in one place
- Impact of a field or program change mapped before you start
- Complexity, dead paragraphs and GO TOs reported up front
- Discovery moved off the mainframe onto your own server
What SMART TS XL gives COBOL teams
Map every dependency
See which programs, copybooks, jobs, files and tables a COBOL program touches, and what touches it.
Impact analysis before change
Follow a field or paragraph through every program that uses it, so a change never surprises production.
Find issues early
Spot dead paragraphs, GO TO tangles, deep nesting and risky logic before they turn into incidents.
Complexity you can plan with
Cyclomatic complexity, program length and GO TO counts for every program, so estimates rest on facts.
Flowcharts that explain code
Interactive flowcharts tied to the original source make unfamiliar COBOL programs readable in minutes.
Keep knowledge in-house
New developers get productive on legacy COBOL quickly, even after the original experts retire.

Which claims programs are the most complex, and why?
The 5 most complex claims programs are CLM4410, CLM2200, PAY2210, CLM0900 and ADJ3100. CLM4410 tops the list with cyclomatic complexity 42 and 17 GO TOs.

ILLUSTRATIVE QUESTIONS AND RESULTS
Built for the way COBOL systems really work
Copybooks and data fields
Trace a field from its copybook definition through every program that moves, computes or tests it, including redefinitions, so data changes are sized correctly.
Program-to-program calls
See static and dynamic CALLs, PERFORM chains and shared modules, so you know exactly what a change to one program can reach.
JCL and batch flow
Connect COBOL programs to the jobs, steps and datasets that run them, and expand JCL to see the real production flow.
Files and SQL
Identify which files and tables each program reads and writes, including embedded SQL, for accurate impact and migration planning.
Dead code and risk
Find paragraphs that are never performed, GO TO tangles and deeply nested logic, and retire or refactor them with confidence.
Ready for modernization
Whether you refactor, rehost or rewrite, start with a complete, measured inventory of your COBOL portfolio and its dependencies.

Questions about COBOL code analysis
What COBOL assets does SMART TS XL analyze?
COBOL programs and copybooks together with the JCL, SQL and other assets around them, so references between programs, jobs, files and tables are kept. Mainframe and distributed code can be analyzed side by side.
Does the analysis run on the mainframe?
No. SMART TS XL runs on your own application server with a SQL Server repository. Source is copied in through FTP, NDM or version-control connectors, so analysis does not use mainframe cycles.
Can our AI assistant analyze our COBOL?
Yes. ASK AI works inside SMART TS XL, and the MCP Connector lets ChatGPT, Claude, Copilot, Gemini or Grok query your indexed COBOL directly. Access is read-only and follows the same permissions your people have.
See COBOL code analysis on your own code.
In a live session we load a sample of your portfolio and analyze your COBOL in the web interface and through the AI assistant you already use.
