/sys$common/syshlp/helplib.hlb PASCAL, Input Output, Text File, MESSAGE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The MESSAGE routine takes a list of expressions and writes  them
  to the standard error file, ERR.  By default, the standard error
  file is bound to standard error.  The MESSAGE  routine  has  the
  same result as WRITELN without a 'file_variable' argument.

  Syntax:

     MESSAGE(expression,...)
