Thank you, thank you, thank you, Mr. Paris.  This makes things crystal clear
for me.  I hate when I have to resort to "it works this way because".  But
the direct mapping makes perfect sense and also makes the error
understandable.

I still need to work on the COPY DD syntax, but I think I can figure it out.
