I think, there are a few small source code changes, but many of the changes will be outside your COBOL source code.

Migrating to COBOL 6 might result in us encountering a slew of problems as a result of COBOL 6 programs treating invalid code or data differently at run time. listed a few things which we encountered,

1. Invalid data in Numeric USAGE DISPLAY data items.
2. Over-populated binary data items.
3. Parameter/Argument size mismatch between the caller and called program.
4. Data items referenced before value assignment.
