Erase Eof Key; Test Reo Key; Reset Key - IBM 3270 Operator's Manual

Operator Console Keyboard

Pressing the ERASE EOF (Erase End of Field) key erases or
blanks character positions in the field in which the cursor is
located. All character positions from the cursor location to the
end of the field are erased. The cursor, however, does not move.
A possible use of this key can be shown by supposing that
you have entered wrong information when keying in an input
field. You could press the Back Tab key to return the cursor to
the beginning of the field, press the ERASE EOF key to erase
the incorrect information, and then key in the correct informa-
tion.
Pressing the TEST R EO key sends a unique signal to the
computer, telling the program that a test message is on the
screen. While this signaling is taking place, the INPUT
INHIBITED indicator turns on, making your keyboard inactive.
The program, replying to the signal, normally turns off the
indicator and tells you what to do next by displaying a message
on your screen.
The TEST REO key is normally used in testing a failing
display station, and certain procedures must be followed. If you
are not fami liar with its use, refer to the appropriate Program
User's Guide or ask your supervisor to explain the procedure(s)
for using this key.
Pressing the RESET key resets the INSERT MODE and INPUT
INHIBITED indicators. However, the RESET key will not reset
these conditions during the short period when your display
station is sending data to, or receiving it from, the computer.
Thus, it may be possible for you to press the RESET key and not
accomplish the desired reset. If this happens, press the key again
to reset the condition.
