Hey again, mona.

Please check the thread "(part 21) Han from China answers
your C questions", in which I gave you a program with
the required functionality. Since any sort of graphics
programming requires tight optimization, plenty of others
have contributed optimizations for the initial program, and
we're still looking for ways to refine the program for
you.

I have come up with a way that uses only the preprocessor:

----- program begins -----
#error -->
----- program ends -------

As you can see, I have used a couple of the optimizations
contributed by others. I have changed "===>" to "-->", for
two reasons: one, using '-' instead of '=' enables certain
scanning devices to encode/compress the program output a
little better and reduces the load on certain older display
devices; two, dropping a byte saves valuable space. There's
talk about changing the --to -in the next release
branch, but nobody has really had the time to write and test
a patch yet.
Yours,
Han from China

Your revised program fails to make use of pointers, plural. Perhaps you
could combine them as follows, similar to how you did with your first
solution using printf?

#include "-->"

A filename is a pointer of sorts, and the error due to not finding the
file will likely print the pointer graphically. The use of ">" in the
filename also shows knowledge of the #include mechanism, that the ">"
won't be interpreted specially inside the quotes, whereas #include -->
would be invalid because the filename doesn't begin with a "<".
