 Caution  In dAsms, the attributes of related files are managed by the file name extension (considering the Windows version)
 . For this reason, the extension ".USC" must be added to the source code.
 No . For source files without this extension, the "Assemble ..." command
  (described later) will be invalid. 

Make the above standard edits to the source text.
