Hello all,
a couple of unsolicited opinions...

Is there any documentation on the AAI and AAO records?

I think the aai and aao are pretty much deprecated, but you should be able
to find them in an EPICS Record Reference Manual.

I find it a bit shame that the aai and aao are not actively supported.
After all, they would provide

the nice features of ai and ao (conversions, limits, etc) for arrays.
This is something that one alway

has to hand-craft to the application when using the waveform record.
And, the waveform

record is thought to be used as an input, although it can be tweaked to
be used as an output, too.

My personal preference is to do as much in the Db as possible (and I have
some very complex databases to show for it). Others may use sequencers or
IOC subroutines or host based tools, instead.

This is my preference, too, and I think this way one can really use the
power of EPICS. But I know there

are lots of people who prefer sequencers or other tools. I just could
not resist to comment on this ;-)
best regards,
Timo
