Pete,

I believe V5R1 introduced the "Read" trigger event.  Still, using a trigger
to enforce security seems a little out of place.  Trigger determines this
record should not be available, pops an exception message to the program,
program blows up unless you've written appropriate error handling into your
app. I would probably go with a logical that omits the FERPA records......

Since you are trying to prevent read access to the data, a trigger will not
be helpful. There is no such thing as a "read" trigger, just Insert, Update
and Delete.

Possibly you could use a view that excludes records with the FERPA flag
set, and restrict direct access to the data.
