Several additional functions are available to manipulate the screen display. These should be included if the terminal supports these features. The functions are: Insert-line (al), Delete-line (dl), Non-destructive-space (nd), Backspace-cursor (bc), Cursor-down (do), Cursor-up (up), Set-width-132 (W3), and Set-width-80 (W8).
After "vi" has rendered the cursor invisible, "ve" is used to make it visible.
If your terminal does not have both a normal and a bright cursor, then set the "ve" entry to turn the cursor on and do not use the "vs" entry.
NS should be added to the terminal database file entry for a terminal that
does not scroll if the lower right corner of the screen is filled. This tells the
ACUCOBOL-GT program that it is all right to use this position. NS is the
complete sequence
( :NS: ).
