In COBOL, you can refer to a data field using its label or by position (using PIC and REDEFINES). For example:
```
01 EMPLOYEE.
05 NAME PIC X(20).
05 AGE PIC 99."
"
To refer to the data field, you can use the following ways:
- By label: `NAME` or `AGE`
- By position: `EMPLOYEE.1` for `NAME`, `EMPLOYEE.3` for `AGE`
