Besides what others said: I would recommend that you start reading an 
intro book.  http://www.gigamonkeys.com/book/ is a very good one, for 
example.  You would benefit more from the comments - right now your code 
is so un-lispy that incremental criticism probably helps very little.

Well, it is written in Lisp, so how can it be un-lispy? :)

I think that *I* know what you mean, but you can't expect someone who
is writing un-lispy code to know what you mean.

So, what do you mean?

I think that others explained that in detail above.

All I meant that OP was not using Lisp idiomatically - which is OK, I am 
sure he will learn it in time.  But foundations are important - what I 
would do in his place is read some of the initial chapters of PCL, then 
come back and look at the comments he got for his code snippet.

Perhaps idiomatic usage would be to use vectors for a vector based
algorithm, and lists for a list based algorithm?
