When the Clear key is pressed, the display screen goes blank (except the
cursor, the operating status line, and the message line).
A host system program can change the way this function operates, allowing
recovery if you accidentally press the Clear key. (See your system operator or
host system operating manual.)
The print function (activated by pressing the Print key) sends a print request to
the host system. If supported, the host system program selects the printer to the
data displayed on the display screen.
To cancel the printing operation of the printer attached to the display station,
press the Quit key (press and hold the Alt key and then pressing the Reset key)
after entering printer setup mode (press the F13/F1 key while pressing and
holding the Alt key.)
The help function (activated by pressing the Help key) provides (1) an
explanation of current error conditions or (2) help information from the host
system. The system must be programmed to provide the Help function. See
Appendix A, "Error Codes and Recovery Procedures" for more information
about error codes.
The hex function is used to enter the hexadecimal value for a character. To
enter a hexadecimal value, press the Hex key while pressing and holding the Alt
key, then enter the corresponding hexadecimal value using the alphanumeric
keys. (Refer to the IBM 5250 Function Reference Manual, SA21-9247, for the
hexadecimal value for each character.)
The play function (activated by pressing the Play key) is used to play back
often-used keystroke sequences (words or sentences) saved in the Function (F)
keys (see the description of the record function). See Chapter 5, "Operations
Using the IBM Enhanced Keyboard" for more information about this function.
Pressing the Test key while pressing and holding the Alt key enables the display
station to run additional display station tests. This key sequence is valid only
when the test pattern is on the screen. See the IBM 3197 Display Model C Color
Station Problem Solving Guide, GA 18-2561, for instructions. Press the Reset key
to exit test mode.
