1 MESSAGE
  Syntax: MESSAGE text
   where: text  is the text of the message

  Writes a message to  the current output device  (selected by `SET DUMP'.
  The default is to the  terminal). This command  is most useful in macros
  to let the user know  what is going on. The  text can include registers,
  parameters etc.,  using the form   `{Parameter,(Format)}'. See HELP Text
  for more details. You can get more fancy and even use `MESSAGE' to write
  fit results to a file in the form of a LaTeX table, for example!
