One would still think that compared to the mere execution (not the whole commands themselves) that'd be some overhead but in practice I guess keeping time in C is fast enough. Or would the overhead still be small? You keep track of time anyway so it would just be a read and print thing? What's the granularity, then? drift? do it in Ada instead? :) -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
