The Del/Ins key can be used to select insert mode. The insert
mode allows you to insert a character or characters into an
existing input field on your screen without destroying data
already there. (There must be nulls [zero characters in the buffer
displayed as blanks] in the rightmost positions of the field where
the insert or inserts will be done.) New characters are inserted at
the cursor position. When this happens, the existing characters
are shifted to the right one position for each character inserted.
The cursor also shifts to the right one position. If you attempt to
insert more characters than there are nulls, the Input Inhibited
indicator comes on, the keyboard locks, and an error message is
displayed.
The insert function is not accepted in the last position of an
input field.
To use the insert mode:
1.
Position the cursor at the location where the data is to be
inserted.
2.
Press the
~
key.
The Insert Mode indicator at the bottom of the display screen
comes on ( •) when the function is accepted.
3.
Enter the data to be inserted.
4.
To leave the insert mode, press the Error Reset key.
Note: If the Error Reset key is pressed during a system recovery
procedure, the display station leaves insert mode. To reenter
insert mode, press the Del/Ins key.
