Insert line
(IL)
CSI Pn L Inserts Pn lines at the cursor. If fewer than Pn lines
remain from the current line to the end of the scrolling
region, the number of lines inserted is the lesser num-
ber. Lines within the scrolling region at and below the
cursor move down. Lines moved past bottom margin
are lost. The cursor is reset to Column 1. Sequence is
ignored when cursor is outside the scrolling region. In
edit mode (DECEDM), if erasure mode (ERM) is reset,
lines that move down into a line with a protected char-
acter field are lost.
