Keyboard Support

CA Spool supports the 3270 CLEAR, ENTER, PA1, PA2, PF1, and PF2 keys. The remaining program function keys (PF3 to PF24) are not supported and are ignored.

The following illustrates the keys and their functions.

CLEAR

Clears and reformats the screen. All queued output messages are written consecutively, starting with the oldest messages.

ENTER

Displays the entered data string in the message output area, and queues the data string to the command processor for execution when pressed after keying or changing data in the command entry area. If no data is keyed or changed, the ENTER key is ignored.

PA1 or PF1

Toggles automatic wraparound to on if it is currently off and conversely. Wraparound off provides more time to read messages. When automatic wraparound is off, messages are queued and not displayed until a key is pressed. To avoid message buildup in CA Spool, a screen of messages is released every 50 seconds.

PA2 or PF2

Cancels, clears and reformats the remaining output lines of the current message. All queued output messages are written consecutively, starting with the oldest messages.
