Hi Eric,

This 'trick' overcomes the limitation of finite string size.
For completeness, I include the relevant parts of db, and .proto files.

getGains {out "CALIB:GAI?"; in "CALIB:GAI?\10\06"
	 "%(\$1Gain:Sts-RB)d,"
	 "%e,"
	 "%(\$1Gain:2-RB.VAL)e,"
	 "%(\$1Gain:3-RB.VAL)e,"
	 "%(\$1Gain:4-RB.VAL)e,"
	 "%(\$1Gain:5-RB.VAL)e,"
	 "%(\$1Gain:6-RB.VAL)e,"
	 "%(\$1Gain:7-RB.VAL)e,"
	 "%(\$1Gain:8-RB.VAL)e";	
	 InTerminator = CR LF; }
-----

record(ai, "$(Sys)$(Dev)Gain:1-RB") {
  field(DESC, "COMPENSATION FACTOR A IN")
  field(DTYP, "stream")
  field(INP, "@I404.protocol getGains($(Sys)$(Dev)) $(PORT) 0")
  field(PINI, "YES")
  field(SCAN, "Passive")
}

record(ai, "$(Sys)$(Dev)Gain:2-RB") {
  field(DESC, "COMPENSATION FACTOR B IN")
}
...
record(ai, "$(Sys)$(Dev)Gain:8-RB") {
  field(DESC, "COMPENSATION FACTOR 3300pF D IN")
}

What version of StreamDevice are you using?  I’ve got a crate monitor prototype file that assigns to a lot more than four records:

query {
    out "Q";
    in ":"
       "SN=%(\$1Serial.VAL)39[^,],"
       "UN=%(\$1Name.VAL)39[^,],"
       "IP=%*[^,],"
       "V3=%d,"
       "V5=%(\$1VP5.RVAL)d,"
       "V+12=%(\$1VP12.RVAL)d,"
       "V-12=%(\$1VM12.RVAL)d,"
#       "VAUX=%*[^,],"
       "T1=%(\$1Temp1.VAL)d,"
       "T2=%(\$1Temp2.VAL)d,"
       "T3=%(\$1Temp3.VAL)d,"
       "T4=%(\$1Temp4.VAL)d,"
       "F1=%(\$1Fan1.VAL)d,"
       "F2=%(\$1Fan2.VAL)d,"
       "F3=%(\$1Fan3.VAL)d,"
       "F4=%(\$1Fan4.VAL)d,"
       "F5=%(\$1Fan5.VAL)d,"
       "F6=%(\$1Fan6.VAL)d,"
       "F7=%(\$1Fan7.VAL)d,"
       "F8=%(\$1Fan8.VAL)d,"
       "F9=%(\$1Fan9.VAL)d,"
       "OT=%*[^,],"
       "OV=%*[^,],"
       "OC=%*[^,],"
       "PS1=%(\$1PS1status.VAL)d,"
       "PS2=%(\$1PS2status.VAL)d,"
       "MSG=%*[^,],"
       "SW=%(\$1PowerSwitch.VAL)d,"
       "PROT=%*[^,],"
       "I3=%*[^,],"
       "I5=%*[^,],"
       "I12=%*[^,],"
       "I-12=%*[^,],"
       "CODE=%(\$1Firmware.VAL)39[^,],"
       "ENET=%*[^,],"
       "POH=%(\$1HoursOn.VAL)g,"
       "MAXTMP=%(\$1MaxTemp.VAL)g,";

    ExtraInput = Ignore;

Hi Yuliang,
Redirection works only for up to 4 values read in (3 redirections). At least that is what I am seeing when increasing number of redirections.
