  83. ECHO     In 64-bit Windows versions either an "external" header file or ECHO is used
  84. ECHO     to create the header.
  85. ECHO     Unfortunately, ECHO inserts an extra line break before the original text.
  86. ECHO [3] The path of the temporary file is hard coded in the embedded DEBUG script.
