The Knuth book has one *huge* chapter for coroutines. In assembly. The target has no stack so there is no problem in context switching :P If you don't need to actively multiprocess they have the *huge* advantage of not needing synchronization. Alternatives are of course state machines or continuation passing, for some problem areas are even better than linear flow.... > Unfortunately co-routines are not familiar to many developers, and have poor > cross-platform support, which makes them harder to use. Mostly because none of the mainstream languages uses them... the most similar thing to them AFAIK are scheme continuation and LUA threads; and of course Haskell monads (more or less...) in a horribly different way :D And, of course, *every* embedded system with a cooperative scheduler at a yield point! -- Lorenzo Marcantonio CZ Srl - Parma
