Thanks, Ned!

I tried that, but it doesn't seem to help... the h/w records still
show SIMM=NO, and they try to access the h/w at startup.  I also set
REC1.PINI=YES, and even added "PP" to REC2.SIML:
 	        field(SIML,"REC1 PP NMS")
just for overkill, all to no avail.

Is it correct to stuff "1/0" into a "YES/NO" field?

Mike,

The simulation link is only "checked" when the record processes. In your
database, it appears that REC2 is Passive, so it won't fetch SIML (REC1) 
until it is requested to process. At that point, it should indicate that 
it is in Simulation Mode.

Yes, a PINI=YES on REC2 would force it to process at initialization and
fall into simulation mode.
