For you lispers out there

When I'm programming in C, I do something like this:

int result;

result = operation(x,y,z);

if (result) return ERR_CODE;

When I look at lisp, there doesn't seem to be any error evaluation or SEH. How do you handle errors in lisp?

Common lisp uses function `signal`, which is like setcontext() a circumcised version of call/cc
