protocol/database macro expansion problem

["Pearson, MR \(Matthew\)" <matthew.pearson@diamond.ac.uk>]

Hi,

I'm trying to get the following protocol function and record to work:

setD {
   out "PID 1,%(\$1.VAL)f,%(\$2.VAL)f,%f";
}

record(ao, "$(P):D_S") {
  field(DTYP, "stream")
  field(OUT, "@ls340.proto setD($(P):P, $(P):I) $(PORT) $(ADDR)")
}

but at IOC startup I get:

2007/06/14 18:20:37.973 Businterface 'BL16I-EA-LS340-01:I)' not found
for 'BL16I-EA-LS340-01:D_S'
2007/06/14 18:20:37.973 BL16I-EA-LS340-01:D_S: Can't attach to bus
BL16I-EA-LS340-01:I) -1
2007/06/14 18:20:37.976 BL16I-EA-LS340-01:D_S: Record initialization
failed
Bad init_rec return value  PV: BL16I-EA-LS340-01:D_S ao: init_record


But if I only use the main PV name, and hard code the last part of the
PV into the protocol file, so that I only have one macro, then this
works. eg.

setD {
   out "PID 1,%(\$1:P.VAL)f,%(\$1:I.VAL)f,%f";
}

record(ao, "$(P):D_S") {
  field(DTYP, "stream")
  field(OUT, "@lakeshore340.proto setD($(P)) $(PORT) $(ADDR)")
}

but this isn't ideal because then two files are dependant on the last
part of the PV name.

Any ideas? Is it because I'm trying to expand two macros?

Cheers,
Matthew
