Above ans is not correct its just opposite
CF is a command function key to transmit changed data as
opposed to CA command attention key, which does not transmit
changed data.

Answer / neha
The CF and CA keywords are used in display files to enable
function keys. CF01 and CA01 both enable the F1 key on your
keyboard. The difference is that a CF (command function) key
updates the fields in your program, while a CA (command
attention) key does not.
A CA key also bypasses any field editing. For example, if
you enter a bad value into a field that has the VALUES
keyword specified in the DDS and then press a CF key, you
will get an error, and the screen will not be returned to
the program because the field doesn't pass validation. If,
on the other hand, you hit a CA key, the editing is
bypassed, and the CA key is returned to the program
(although the fields are not). The best use for CA keys is
keys that exit a screen without updating data--typically,
CA03 or CA12 in iSeries applications.

Answer / priya
CA does not retains the value into the buffer memory.
CF retains the value into the buffer memory.If we have
F3=Exit defined with CF in display File,in debug give F3 in
screen ,then it returns control to Debugging Program.For CA
,it comes out of debugging program.

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.

Answer / ardeep
CA Transfers data (i.e the indicator values) from the
Workstation/Display file to the RPG program. And we can use
that value in our programming logic.
Example -> F3 - Exit option on all the AS400 screens.
CF dosen't transfer any value. We can use the indicator
value only inside the Workstation/Display file and not
outside it.
