Summary

- Issues
- event base vs. state based
- power vs. clarity

- sequential vs. concurrent
Semantics Alexander SPI (i)
- Two part specication:
- EventCSP - pure dialogue order
- EventISL - target dependent semantics
- dialogue description - centralised
- syntactic/semantic trade-off - tollerable
Semantics - raw code
- event loop for word processor
- dialogue description
- very distributed
- syntactic/semantic trade-off
- terrible!
