Try some more subtle examples. On a proper POSIX-type system:
 
     QUOTE='"'
     ./test "Hello World" ${QUOTE}Hello World${QUOTE}
     Hello World
     "Hello
     World"
 
Try to get the equivalent in DCL:
 
     quote = """"
     «rigmarole equivalent to ./test» "Hello World" 'quote'Hello

World'quote'

 
What’s it going to print?

bash and DCL are different.

I am utterly baffled as to why you continue to regularly
engage with this troll.  It's your choice, of course, but
getting the backsplatter is unpleasant for rest of us who
have already plonked him.
