Doug,
There is an article from MC Press that might help you out.
It's titled: TechTip: Checking for User-Changed Screen Data by Doug Eckersley and it was just published this month.

I have a question that has bothered me for sometime now, regarding how to properly handle entry in a subfile. I will attempt to put this into context of a three field subfile containing ten rows. All three fields are type ALPHA, 5 characters in length.... Using RPG I can check the subfile to see if there were any records that were changed, IE: added and can then verify the data before writing it to the file. In theory that is fandamntastic. However what is the proper way to handle say the second row of data where the user initially entered something and then decided naw, isn't needed or was a mistake so they removed it. If I understand how the next changed record works, it will come up with both lines 1 and 2 even though 2 really has not been changed.....IE: no data contained within. Suggestions? Or do I need to check each possible line and if there is no data, end the processing.
