3.4.3 Editing Data
3.4.3.1
Defining
the
Editing Mode
The
"Editing
Mode" determines
the
effect
of
data entered from
the
keyboard
and the
range
of
characters affected
by
editing.
The
Editing
Mode
may be set in
Set-Up
or by
using
an
escape sequence.
Entering data from
the
keyboard
can be
done
in one of two
ways:
Replacing (overwriting) characters,
beginning
at the
cursor
Inserting characters,
beginning
at the
cursor
The
range affected
by
inserting
or
deleting characters
may be
line (from
the
cursor
to the
end*
of the
line)
page (from
the
cursor
to the
end*
of the
page)
*
Data exceeding
the end is
lost.
The
combination
of
these
two
factors then defines four
editing
modes:
