| description | Modernization analysis heuristics, complexity scoring rubrics, migration wave planning guidance, and interpretation of COBOL knowledge graph metrics. Use when graph-query, complexity-scorer, or migration-advisor needs to interpret results or make recommendations. |
| Score | Category | Interpretation | Typical Effort |
|---|---|---|---|
| 1-25 | EASY | Leaf programs, low coupling, clean structure | 3-7 days |
| 26-50 | MODERATE | Some coupling, possible REDEFINES, medium size | 1-3 weeks |
| 51-75 | HARD | High coupling, GOTOs, large size, shared copybooks | 1-2 months |
| 76-100 | CRITICAL | ALTER present, circular deps, 2000+ lines | Evaluate rewrite |
Target: EASY programs with zero inbound calls Goal: Build Java muscle, establish patterns, prove the toolchain Criteria:
MATCH (p:Program)
WHERE p.migration_category = 'EASY'
AND NOT ()-[:CALLS]->(p)
RETURN p.program_id ORDER BY p.migration_score
Target: MODERATE programs that are highly called (high fan-in) Goal: Replace shared subroutines with Java services others can call Criteria:
MATCH (p:Program)<-[:CALLS]-(callers)
WHERE p.migration_category = 'MODERATE'
RETURN p.program_id, count(callers) AS fan_in
ORDER BY fan_in DESC
Target: HARD programs after their dependencies are migrated Strategy: Strangler fig pattern — wrap in Java, migrate incrementally
Target: CRITICAL programs Decision point: Full rewrite vs. keep-and-wrap Tools: Anti-corruption layer pattern
| Metric | Good | Warning | Critical |
|---|---|---|---|
| Average fan-in (incoming calls) | < 3 | 3-8 | > 8 |
| Programs with GOTO | < 5% | 5-15% | > 15% |
| Programs with ALTER | 0 | 1-2 | > 2 |
| Copybook usage breadth | < 5 programs | 5-10 | > 10 |
| Circular dependency count | 0 | 1-3 | > 3 |
"Where should we start migrating?" → Run complexity-scorer, then query EASY + zero fan-in programs
"What breaks if we change X?" → Run impact-analyzer on X
"Which copybook change would cause the most disruption?" → Query copybooks ordered by program usage count (descending)
"Are there any dead programs (never called)?"
MATCH (p:Program)
WHERE NOT ()-[:CALLS]->(p) AND NOT ()-[:EXECUTES]->(p)
RETURN p.program_id, p.line_count
ORDER BY p.line_count DESC
COBOL anti-patterns, modernization signals, and risk patterns to identify during parsing and analysis. Use when evaluating COBOL code quality, flagging migration risks, or assessing programs for Java conversion feasibility.
COBOL language grammar, division and section structure, PIC clause syntax, level numbers, procedure division verbs, and language construct reference. Use when parsing, analysing, or explaining COBOL source code structure.
Proven Cypher query and write patterns for the LegacyCobolInsights graph. Includes MERGE templates for ingestion, common traversal queries for analysis, and aggregation patterns for reporting. Use when writing to or querying Neo4j.
