It's just simple.CA keys are used to pass data from display device to your program or reading screen data and return gives control to your program
CF keys are usually used to don't any data from display device to program or with out reading screen data before giving control to your program.
So CF03 = exit usually used for existing screen,no need to pass data.
CA06 ,CA08 are usually used to add a record or to update a record,it means necessary you need to pass some action or data.
