  3. To delete a parameter, select the parameter that you want to delete and click Delete.

  5. Select the style of parameters that you want to use.
  6. If the function requires values for all of its parameters, select Return null on null input.
  7. If the information that this function uses is not used again, select Pass a final call indicator.
