I have what I hope is a quick question about StreamDevice:

For protocols that parse a response with multiple values and use

Protocol arguments to specify the names of several records that the

values are written to, is there any way to update the STAT and SEVR

fields for ALL the affected records, not just the one that called the

protocol via its INP field?

If there is no way to get the StreamDevice layer to do this, how about

some record logic to do so?

I tried to simply copy the STAT and SEVR values to other records using a

seq record processed via an FLNK , but not surprisingly that just

generates "Attempt to modify noMod field PV" errors.
