Hi Stephanie,
I haven't changed dbst, I simply report out fields that are different
from the default.  It is
possible that dbStaticLib has changed.  
I believe the problem is that global link fields are  really strings, 
so the default is the empty string rather
than 0.00000000000e+00 (as it appears in all the capfast symbols).
I had a problem with DOL fields inadvertantly initializing analog out
records to 0.0.
I went through  and did a global edit on .sym files
that have DOL fields  and changed def(DOL) from 
def(DOL):0.000000000000000e+00 
to 
def(DOL):
This fixed our problem with analog outs.  
However, I think this should probably be done for all the other LINK fields.
INP, FLNK, INPA, INPB   etc.
