You can find the most amazing examples of unreadable code. This is a basic interpreter written in C:

[Code]
#define O(b,f,u,s,c,a)b(){int o=f();switch(*p++){X u:_ o s b();X c:_ o a b();default--;_ o;}}
#define t(e,d,_,C)X e:f=fopen(B+d,_);C;fclose(f)
...

Does'nt compile..

I suspect it was written as a joke; look at the name of the top define and it's arguments... "Obfuscated C...." which was the beginning of the name of the contest Tom was referring to.

Unexpectedly, the code for these contents taught a lot about using subtle and under-appreciated aspects of C (or Fortran, etc.).

If someone were to propose an "Obfuscated RPL Program Contest" I wonder if casual readers could even recognize what the goal was by just looking at the programs?

It should compile. You probably need some more info. There is a make file provide as well. Have a look here and search for dds.
