Delete line
(DL)
CSI Pn M Deletes Pn lines, starting at the line with the cursor.
If fewer than Pn lines remain from the current line to
the end of the scrolling region, the number of lines de-
leted is the lesser number. As lines are deleted, the
lines within the scrolling region and below the cursor
move up, and blank lines are added at the bottom of
the scrolling region. The cursor is reset to Column 1.
Sequence is ignored when cursor is outside the scrol-
ling region.
In edit mode (DECEDM), if erasure mode (ERM) is
reset, DL cannot delete lines that have protected char-
acters. As lines are deleted, the area moved up is
bounded by the bottom of the scrolling region, or by
the next line with a protected character field.
Insert charac-
ters (ICH)
CSI Pn @ Inserts Pn blank characters at the cursor position,
with the character attributes set to normal. The cur-
sor does not move and remains at the beginning of the
inserted blank characters. A parameter of 0 or 1 in-
serts one blank character. Data on the line is shifted
forward as in character insertion. In edit mode
(DECEDM), if erasure mode (ERM) is reset, text
moved into a protected character field is lost.
Delete char-
acter (DCH)
CSI Pn P Deletes Pn characters, starting with the character at
the cursor position. When a character is deleted, all
characters to the right of the cursor move to the left.
This creates a space character at the right margin for
each character deleted.
Character attributes move with the characters.
Spaces created at the end of the line have all of their
character attributes off. In edit mode (DECEDM), if
erasure mode (ERM) is reset, DCH cannot delete pro-
tected characters.
