> A potentially useful SELECT function would be one which took an array of channels and directions That would actually be even a better idea than my present SELECT function, but I don't have a good solution yet for the (receive) variables. The best I can think of is just an array for the values, but that needs a lot of extra copies. I would rather prefer a built-in function than a separate module as in Go. > OBERON SA seems to have evolved in a direction converging upon C Not sure what you mean.
