Dehong, You can't get a value from another record at init_record time. In fact, you wouldn't want the value even if you could get it, because the record supplying the value might not have executed its own init_record routine.

Hi,

It seems whenever I try to call dbGetField within init_record (to get value from another
record, when pass==1) the epics environment (iocInit) blows up with the following message:
A call to "assert (dbLockIsInitialized)" failed in ../dbLock.c at 239

Could you expert guys enlighten me? How to work around it?

Thanks much and best regards,
Dehong
