Conversion rules
Hyphens become underscores
All hyphens are replaced with underscores before case conversion is applied.
ACCOUNT-BALANCE → account_balance
Numbers are preserved
Numeric segments are kept as-is in both Python and Java output.
ADDRESS-LINE-1 → address_line_1 / addressLine1
Python: everything lowercase
Snake_case: all words lowercase, joined by underscores.
WS-TOTAL-AMOUNT-PAID → ws_total_amount_paid
Java: camelCase
First word lowercase, subsequent words capitalised.
WS-TOTAL-AMOUNT-PAID → wsTotalAmountPaid
Strip prefixes (optional)
Toggle removes WS-, LV-, GV-, LS- working-storage prefixes before conversion.
WS-DATE-OF-BIRTH → date_of_birth / dateOfBirth
Space-separated input
Each token is treated as a separate variable name to convert. Mix lines and spaces freely.
GV-EMPLOYEE-ID → gv_employee_id / gvEmployeeId
Need the full migration, not just variable names?
Language Foundry's transpiler converts entire COBOL and RPG IV codebases to idiomatic Java 21 — data types, business logic, embedded SQL, and all. Variable names are just the beginning.
