Press the FIELD key to advance to the next portion of the ACE. 4. Press the ITEM key to select the desired option or access. 5. Repeat steps 3 and 4 until you have selected all options and access modes. Then, press the ENTER key to add the ACE to the file's ACL. 6. Repeat steps 2 to 7 until you have added all ACEs. Then, press Ctrl/Z to finish the editing session and return to DCL. To return to the keypad diagram, press the Return key.
