Hi all- I'm trying to use simulation mode for the first time and am having
trouble getting it to work.  I hope someone out there may be able to tell me
what I'm doing wrong.  I have no doubt it's a thinko on my part!

In the .db file (record names have been changed to protect the innocent):

	grecord(bi,"REC1") {
	        field(DTYP,"Soft Channel")
	        field(INP,"1")
	}
	grecord(mbbo,"REC2") {
	        field(DESC,"IO Control")
	        field(DTYP,"SR830")
	        field(NOBT,"2")
	        field(OUT,"#L$(L) A$(G) @2")
	...etc
	        field(SIML,"REC1")
	}

I want the SIMM field of REC2 to be controlled by the REC1.VAL, at IOC boot,
so that the mbbo never goes to talk to the real (non-existent) device.  Am I
wrong in expecting REC2.SIMM to be set from REC1.VAL via the REC2.SIML DB link?
"dbpr" shows that REC1.VAL is indeed 1, but REC2.SIML/.SIMM never get set.

I'm doing it this way because there are quite a few REC2's.

Maybe it's a confusion between YES/NO vs. 1/0; how does one load a YES/NO
field via a DB link?  Do I need a PINI somewhere?  Is there a better way to
propagate SIMMs across a DB?

thanks,
Mike
