The first problem I have found in the thought-experiment is deriving a "initial rotation finished" signal. The rest seems reasonably straightforward with arithmetic functions and mux components. stepgen-cmd = stepgen-start + 100 * (new tool - old tool) + 30 is easy enough. -- atp ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
