Any hint on how to monitor the display error in a generalized way ???
There is a "real" solution - and then there are assorted hacks. I
suspect that the real solution is going to require less code!
You need to extend the data you store to add some form of "level
check". The current level would be stored in the DB (or a data area
or ...) and whenever you retrieve stored record you would compare its
level to the current one. If it is not current then Inz. You then must
ensure that you update the master level number when a change is made.
You don't say what release you are on - but if you are on V5R4 or
later you could try using a DS result field on the EXFMT and populate
the display fields using an EVAL-CORR which you place in a MONITOR
group. If you are on an earlier release then you will have to use a
monitor group with a series of hand-coded evals (one for each numeric
field) to see if any blow up.
As I said - the "correct" answer is not only better - but probably a
lot less code!
