Andrew,

I don't know if this matters but my waveform is actually one of the

outputs of a genSub record. It has a NOVA field but I could alternately

use another output as a array length indicator field.

BTW, I am also open to doing this in EDM or MEDM or ???

Hi Michael,

I too have had trouble doing this.  I was able to setup a rule to set
the buffer size from the NORD field of a waveform record.  The result
was that, when the size was reduced, the start of the waveform was
removed instead of the end.  So not very useful.

Also note that the NORD field of a waveform record does not get monitors
posted on it unless there is device support that explicitly does that, so this
wouldn't necessarily work too well anyway (you could forward-link the waveform
record to a longin that reads the NORD field and use that instead though).

In 3.15 any device support will still be responsible for posting monitors if
it sets NORD, but the record and soft device support will also do it when they
set NORD.
