ECHO
------------------------------------------------------------------------------

  Purpose : ECHO script commands or text to the screen

  Syntax  : ECHO ON|OFF <cString>

  Default : OFF

  ECHO <cString> causes <cString> to be echoed to the screen regardless
  of, and without affecting, the ECHO status.  ECHO ON <cString> turns on
  echoing of the script file to the screen, with the first line displayed
  being <cString> if it is specified.  ECHO OFF turns off echoing to the
  screen of the script file and ignores the rest of the line.
