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.
