Basic Examples  (2)

The default channel for messages is standard output:

Wolfram Language code: $Messages

Have messages go to a temporary file and the default channel:

Wolfram Language code: stream = OpenWrite[]
Wolfram Language code: $Messages = Append[$Messages, stream]

Generate a message:

Wolfram Language code: 1 / 0

Show the contents of the temporary file:

Wolfram Language code: FilePrint[stream[[1]]]

Clean up by resetting $Messages to its default and closing the stream:

Wolfram Language code: $Messages = $Messages[[{1}]]; Close[stream];
