How COBOL Bridge Transpiles COBOL to Python
COBOL Bridge uses AI-powered transpilation to convert legacy COBOL programs into clean, idiomatic Python. Unlike simple syntax converters, COBOL Bridge understands business logic and produces maintainable, well-documented code.
Input: Legacy COBOL
IDENTIFICATION DIVISION.
PROGRAM-ID. ACCOUNT-BALANCE.
DATA DIVISION.
WORKING-STORAGE SECTION.
01 BALANCE PIC 9(10)V99 VALUE 0.
01 DEPOSIT PIC 9(10)V99.
PROCEDURE DIVISION.
DISPLAY "Enter deposit amount: ".
ACCEPT DEPOSIT.
ADD DEPOSIT TO BALANCE.
DISPLAY "New balance: " BALANCE.
STOP RUN.
Output: Modern Python
class AccountBalance:
"""Transpiled from COBOL ACCOUNT-BALANCE program."""
def __init__(self):
self.balance: float = 0.0
def add_deposit(self, deposit: float) -> float:
self.balance += deposit
return self.balance
def main(self):
deposit = float(input("Enter deposit amount: "))
self.add_deposit(deposit)
print(f"New balance: {self.balance:.2f}")
if __name__ == "__main__":
AccountBalance().main()
