Hi Phil,

I think you can do this with the subarray record, taking advantage of the fact that the scalar value
of an array is the value of its first element.  I haven't tried this, because I would in any case do it
with an acalcout record.  To write element 23 of myArray.VAL to myScalar.VAL, whenever myArray
is posted, I would do this:

acalc.INAA = "myArray.VAL CP"
acalc.CALC = "aa[23,23]"
acalc.OUT = "myScalar.VAL PP"

Subject: Use element of waveform as input to ai record

Hello all,

Sorry if this is obvious thing I have missed, but I am not finding any
obvious way to do what I am trying.

I would like the value of an ai record to be set to the value of an
element in a waveform, and update when the waveform up dates.

Thanks,

Phil Sorensen
