Input errors
During macro playback, the host terminal reacts to a key input error in the same way as it would react if an actual user had typed the key.
For example, if an Input action sends a key that displays a character (such as a, b, c, #, & and so on) to the session when the text cursor is not located in a 3270 or 5250 input field, then the session responds by inhibiting the key input and displaying an error symbol in the Operator Information Area, just as it would with a keystroke typed by an actual user.
