you know what
if result < 0 then
        return Multiwaysearch(keyList, links[abs(result)],end,searchKey)
    end if
end if


should be

Multiwaysearch(keyList,searchKey)
.
.
.
.


if result < 0 then
        return Multiwaysearch( links[abs(result)],searchKey)
    end if
end if

no need for start and end 
but this will cause and infinite recursion if NO MATCH...

lets see if someone has taken Algorithm Analysis class.
