## Author's comments:
It is possible to write some kinds of programs in C without using reserved
words. For very short and trivial programs, it usually isn't very hard to
write a variant using no reserved words, but with this program I want to
show that also non-trivial programs can be written this way. This IOCCC
entry contains no reserved words (I don't count 'main' as a reserved word,
although the compiler gives it special meaning) and no preprocessor
directives.

The program is a small ray-tracer. The first line of the source code may
be modified if you want the resulting image to be of some other resolution
than the predefined. The 'A' value is an anti-alias factor. Setting it to
1 disables the anti-aliasing feature (this makes the output look bad), but
setting it too high makes the trace take a lot more time to complete.

The ppm image can then be viewed using an image viewer of your own choice.
(Running the ray-tracer may take several minutes, even on fast machines,
so be patient.)

I am very much aware about the fact that I'm breaking the guidelines. For
example, the word 'int' is a reserved word and therefore all variable
declarations are implicit. There will no doubt be _lots_ of warnings,
no matter which compiler is used. Still, the source code should be word-
length-independent and endianess-independent.
<humor>
Another reason for writing code without using reserved words is that many
text editors will make all reserved words turn BOLD when printed on
paper. Since I care for the global environment, we shouldn't waste any
more laser toner, or ink, than necessary. Everyone should write C code
with no reserved words, and our world will be a better place.
