Latch Record ?

["Paul Sichta" <psichta@pppl.gov>]

First off,  Happy Thanksgiving to my American collaborators and their
families.

I want to have a record (or record-set) which emulates a set-reset latch.
My application is to provide a 'processing-active' flag set while a group of
record processing and sequences are active.

The BO record does this (latching function) from a medm page using dbPuts to
the VAL field,  but I want the same effect based on database processing
links.  That is,  an FLNK from record 'A' should set the latch (VAL =1),
and an FLNK from record 'B' should reset the latch (VAL=0).

I feel like I can't see the forest thru the trees on this one.
