Logic to get which all fields are INITIAL from a group of fields fetched

Hi All,

I am stuck in one scenario. Through a web page I am updating some fields in a Z table.

Now there are some particular fields ( 20 in number) on channge of any of which i have to trigger an event.

One way is to fetch all of them into work areas and check whether they are initial or not.But that's very

crude way of doing it.I will want to know whether there is any other way of doing it.

I just have to know whether any of them is 'NOT INITIAL'.

Thanks in advance,

saket.
