[rc5] Blocks

I recently read the rc5.ps file describing the rc5 algorithm.
My question is in the blocks.
What do the numbers represent?
For example in a block: 64E1E5C6:D0000000 ?

Another thing is (for those who have read the paper) that the algorithm
has
a + operation. It sais is the modulo-2^w addition. What is this?
How can I implement this in C?

Thanks

PS: Isn't there a c programm for performing the algorithm? For exmple
the
libdes library has a program mnamed des.
