$NewMessage

$NewMessage
is a global variable which, if set, is applied to the symbol name and tag of messages that are requested but have not yet been defined.
  • $NewMessage is applied to the symbol name, tag, and language of a message if an explicit language is specified.
  • Mathematica looks for the value of or after $NewMessage has been applied.
  • You can set up $NewMessage to read the text of messages from files when they are first needed.
