Hi Michael,

I am running base-3.15.2.

.db test :

record(ai, "$(P)$(R)dumm")
{
  field(DESC, "just a test")
  field(DTYP, "stream")
  field (EGU, "grad")
  field(INP,  "@RTO1024.proto dumm($(P)$(R)PosPeak,$(P)$(R)NegPeak,$(P)$(R)Average,$(P)$(R)RMS,$(P)$(R)StdDev,$(P)$(R)EvntCount,$(P)$(R)WFMCount) $(PORT) $(A)")
}

proto

dumm {
  out "MEAS1:ARES?";
  in "%f,%(\$1)f,%(\$2)f,%(\$3)f,%(\$4)f,%(\$5)f,%(\$6)d,%(\$7)d";
}

leads to :

2016/04/28 14:40:09.581567 _main_ Missing ')' after substitutions 'dumm(RTO1024:Test:PosPeak,RTO1024:Test:NegPeak,RTO1024:Test:Average,RTO1024:TestL0'
2016/04/28 14:40:09.581649 _main_ RTO1024:Test:dumm: Protocol parse error
2016/04/28 14:40:09.581666 _main_ RTO1024:Test:dumm: Record initialization failed

still 80 characters?
