Subject: dynamic INP/OUT evaluation

Hi,
I'm writing a driver for a serial IP module (in-house) with
a VME_IO type of the INP and OUT field string:
#Cn Sm @parameter

I want to allow dynamical changes of n, m and parameter.
Do I have to make a copy of n, m & parameter and compare it
to identify changes or is there a kind of flag that the field has changed?
Is there a way to ask the database?
I think it is possible to have a special processing in record support if
a field has changed. That would be the most elegant way to my opinion.
But my driver will support roughly a dozen types of records and I don't
want to rewrite them all. 

Regards
Andreas
