Trouble with Limit[I ... k]/k, k-> Infinity]

I am struggling to valuate an intermediate result in a long calculation and I get stuck with terms like this one: Limit[Exp[I k A]/k, k -> Infinity, Assumptions -> {A != 0, A \[Element] Reals}] In the actual expression, A are somewhat more complicated expressions but I am willing to tell Mathematica by hand that they are real and non-zero, however, it still doesn't work. I don't see that there is a problem in mathematical terms so how can I convince Mathematica to give me an answer? Actually, Mathematica 5.1 does not mind telling me the result of Limit[Exp[I k]/k, k -> Infinity] At the moment I am relying on a kludge relying on pattern-matching but I am not very good at it so there might be a point to help me on. Any input or help will be greatly appreciated. Thanks, Christian
