Use the following table to choose the correct run option for a UDF.
| Situation | Run Option |
|---|---|
| You are in the UDF development phase and are debugging a function. | EXECUTE PROTECTED. |
| Function opens a file or uses another operating system resource that requires tracking by the operating system. | EXECUTE PROTECTED. Running such a function in nonprotected mode could interfere with proper Vantage operation. |
| Function is a computational function that does not use any operating system resources. | EXECUTE NOT PROTECTED. Running a UDF in nonprotected mode speeds up the processing of the function considerably. Use this option only after debugging the function. |
