When you press and hold the Alt key, then press the Clear key, the display
screen goes blank (except for 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. Call your host system operator
or refer to the host system operating manual.
The erase input function erases the display screen and moves the cursor to the
first input position on line one. To operate this function, press and hold the Shift
key, then press the Erase Input key.
When the display station is under program control, this function erases all the
characters from an input field and moves the cursor to the home position
(usually the first input position of the first input field) on the display screen.
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 for
printing the data displayed on the display screen.
To cancel the printing operation of the printer attached to the display station,
press the Quit key (pressing and holding the Alt key and then press the Reset
key) after entering printer setup mode (press the SetUp 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 host 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 a
hexadecimal value for each character.)
