OutputAutoOverwrite
is an option for notebooks that specifies whether the output of a command should replace any existing output from a previous evaluation.
Details

- With the default setting OutputAutoOverwrite->True, the output from a command overwrites any previously existing output. Only those output cells that have CellAutoOverwrite set to True can be overwritten.
- With the setting OutputAutoOverwrite->False, output from each evaluation of a command is printed in the notebook. The output is printed directly after any previously generated output.
