3276na Emulation Mode
Insert Key
IBM 3276. During normal operation, your terminal overwrites existing text when you enter
characters onto a line. To type in characters without overwriting text requires your setting
the terminal for Insert mode.
Pressing the
INSERT
key puts the terminal into Insert mode. To return the terminal to its
normal overwrite operation requires your pressing
t~e
RESET
key or any key that causes
host communicatication (such as the
ENTER
key, the
PA
keys, or the
PF
keys).
The effect of Insert mode depends upon the screen's format:
• In an unformatted display, as you insert characters, existing text is shifted to the right.
These characters may wrap across lines or from the bottom line of the display to the top
line.
• After entering Insert mode, if you try to enter a character into a protected field or an
attribute byte, the keyboard locks and the
((Go Elsewhere"
message appears in the Status
Line.
• If the cursor is within an unprotected field, you may insert characters into the field as long
as space is available between the cursor's current position and the end of the field. Charac-
ters forced from one line automatically wrap to the next line. When the field to the right of
the cursor completely fills with data, the keyboard locks, and the message
~,
((Too Much Data"
appears in the Status Line.
J
HP 2625A. Insert mode functions similarly. If you attempt to add more data than the field
can accommodate, the message
UX
Too Much Data"
appears in the Status Line. To enter
Insert mode, press the
III
key. You may exit Insert mode as you do on the IBM 3276.
Additionally, you may again press the
III
key to cancel Insert mode. (This follows the HP
practice of exiting Insert mode; this feature is not provided on a 3276.)
Delete Key
IBM 3276. The operation of the
DELETE
key depends on the screen's format:
• Within an unprotected field (or with an unformatted display), pressing the
DELETE
key
erases the character at the cursor's current position. The cursor retains its position while
the remaining characters within that field (up to the end of the line) shift one position to
the left. Subsequent lines are unaffected.
• If you press the
DELETE
key when the cursor is within a protected field or an attribute
byte, the keyboard locks and the
((Go Elsewhere"
message appears in the Status Line.
HP 2625A. Pressing the •
key duplicates the delete operation of the 3276. (However,
continuing to hold down the •
key repeats the delete operation. The 3276 does not provide
this feature.)
