- This message is generated when operations that require a notebook front end are evaluated in a Mathematica kernel that is not connected to a notebook front end.
- This message can be generated by functions that manipulate notebooks, such as NotebookPut and SelectionEvaluate, and functions that use the notebook front end, such as .
- This message is normally seen only when using the Mathematica kernel without a notebook front end. If you see this message in a situation where it is not expected, please contact Technical Support.
- Off[message] switches off the message; On[message] switches it on. For example: Off[FrontEndObject::notavail].
