  Hi Murali,

I think the answer is supposed to be E. As Eric alluded to earlier, this 
wording is a bit ambiguous. When a user hits the Enter key, the program 
can process the data stream. It does not happen in a real-time event 
based manner as one might expect if one is familiar with Java or Windows 
or other GUI programming.

So, if the question is read as 'How can an RPG program know when a user 
inputs a character on a display file', the answer is "F - None of the 
above".

However, the CHANGE keyword can be used to turn on an indicator when the 
user hits the Enter key if the user typed anything on a field in the 
record format to which the CHANGE keyword applies. This includes typing 
the same value into a field which was there before.

If you want more details about DDS keywords, see the IBM Info Centre:

HTH,
Adam
