I thank you very much for your reply. Changing the path to the absolute path
did not change the error message. In case of DX debugger, I am not quite
sure how I can set it. I am sorry, but I am quite new to DX.
However, I am including both the .fx file and program file below. The files
can help to find out what the problem might be. This program is a blue copy
from T. Miller's book(chapter 11, op.193-205). I have slightly modified it
with
respect to the April release .
Again I thank you very much for your consideration.
