Hi,
Can one use the output of a calc or a calcout routine to set values for HIHI, HIGH,
LOW, and LOLO?  When I load my database, I always get errors in these lines.  Is
there some sort of special incantation that I must do?

Here's what I have.  I've used camonitor to check that all of the records leading
up to and including the calc records work as expected.  For the calcout routines,
I have a value between 0<= VAL <=1 for ILimMajor and ILimMinor.  The calcout
records appear to do what I want them to do:

======================================
record(calcout, "$(user):calcQ1I_HiHi") {
	field(DESC, "Q1 I Max Major limit")
	field(PREC, "3")
	field(INPA, "$(user):Q1SetCurrent.VAL  NPP NMS")
	field(INPB, "$(user):ILimMajor.VAL  NPP NMS")
	field(CALC, "A+(A*B)")
}
record(calcout, "$(user):calcQ1I_High") {
	field(DESC, "Q1 I Max Minor limit")
	field(PREC, "3")
	field(INPA, "$(user):Q1SetCurrent.VAL  NPP NMS")
	field(INPB, "$(user):ILimMinor.VAL  NPP NMS")
	field(CALC, "A+A*B")
}
record(calcout, "$(user):calcQ1I_Low") {
	field(DESC, "Q1 I Min Minor limit")
	field(PREC, "3")
	field(INPA, "$(user):Q1SetCurrent.VAL  NPP NMS")
	field(INPB, "$(user):ILimMinor.VAL  NPP NMS")
	field(CALC, "A-A*B")
}
record(calcout, "$(user):calcQ1I_LoLo") {
	field(DESC, "Q1 I Min Major limit")
	field(PREC, "3")
	field(INPA, "$(user):Q1SetCurrent.VAL  NPP NMS")
	field(INPB, "$(user):ILimMajor.VAL  NPP NMS")
	field(CALC, "A-A*B")
}
record(ai, "$(user):Q1ReadCurrent") {
	field(DESC, "Q1 Magnet Readback Current")
	field(PREC, "3")
	field(INP,  "$(user):rampQ1Current.VAL NPP NMS")
	field(EGUF, "10")
	field(EGU,  "A")
	field(HOPR, "2000")
	field(LOPR, "0")
	field(HIHI, "$(user):calcQ1I_HiHi.VAL")
	field(HIGH, "$(user):calcQ1I_High.VAL")
	field(LOW,  "$(user):calcQ1I_Low.VAL")
	field(LOLO, "$(user):calcQ1I_LoLo.VAL")
	field(HHSV, "MAJOR")
	field(HSV,  "MINOR")
	field(LSV,  "MINOR")
	field(LLSV, "MAJOR")
	field(FLNK, "$(user):Q1RampCurrent.PROC")
}
======================================
Thanks,
Pierrick
