While we can argue that macros can be rewritten to avoid it, I don't think it's evil when composing a translate table for example. If the code path is conditional, for example with a slower fall-back routine for when machine type has been tested during execution, then Ed's approach with the ACONTROL might be justified. But there might be more than just the question whether the CPU can do it; maybe you also want you development tools (and developers) well enough aware of the new instructions to avoid mistakes. Rob
