- Control flow compared to an X-Midas primitive:
  - (If you've never written an X-Midas primitive you can just ignore this slide.)
  - In NeXtMidas synchronization is automatic, in X-Midas it is manual and requires an explicit call to `M$SYNC`.
  - In NeXtMidas the process loop (and any checks for break) is automatic, in X-Midas it is manual and must be done in the primitive.
