I've seen references to AAI and AAO records someplace, which I assume are Array Analog Input and Output. Is support for that put in the device driver? The aai and aao records are a bit of an anachronism; they're not really used very much, there's no soft or test device support included in Base, and they're not documented anywhere either. I think they were contributed by one site a long time ago, and we just haven't got around to removing them yet (they'll be gone if R3.15 is ever released). I have a condition working with the Multilin control relays, where I need to be able to generate a multiple register output sequence, where the entire sequence is done in a single record. This would fit that perfectly, I think. Use a waveform record if you want device support where the whole array comes from a CA client. However if you're going to want to be able to set some individual elements from another record they you'll be much better off writing device support that takes the higher level parameters and combines them into the appropriate array/sequence internally. - Andrew -- There is considerable overlap between the intelligence of the smartest bears and the dumbest tourists -- Yosemite National Park Ranger
