EDIT Subcommands-LONG, NEtT LONG Use the LONG subcommand to cancel a previous SHORT subcommand request.
The format of the LONG subcommand is:
r I LONG , L- When the LONG subcommand is in effect (it is the default), the editor
responds to invalid subcommands with the message: ? EDIT: line ••• None.
NEXT Use the NEXT subcommand to advance the line pointer a specified number
of lines toward the end of the file. The line pointed to becomes the
new current line. The format of the NEXT subcommand is:
r------ , 1 r , , 1 Next 1 nl , 1 111 I 1 L .J
1 L- -.J n indicates the number of lines to move the line pointer. If n is
omitted, then the pointer is moved down only one line. NEXT is equivalent to DOWN and FORWARD. When verification is on, the new current line is displayed. If the end
of the file is reached, the message: EOF: is displayed.

EDIT Subcommands-OVERLAY OVERLAY Use the OVERLAY subcommand to selectively replace one or more character
strings in the current line with the corresponding nonblank characters
in the iine being keyed in. The format of the OVERLAY subcommand is:
r---- I Overlay L- , [line]
line specifies an input line that replaces corresponaing character
positions in the current line. On a typewriter terminal, if you
enter the OVERLAY subcommand with no data line, input record
remains unchanged.
1. Blank characters in the input line indicate that the corresponding
characters in the current line are not to be overlaid. For
o L
Blanks in columns 3, 4, 5, and 6 of the OVERLAY line indicate that
columns 1, 2, 3, and 4 of the current line are not to be changed. (At least one blank must follow the OVERLAY subcommand, which can
be truncated as 0). 2. This subcommand may be entered at a typewriter terminal by typing
the letter "0", followed by a backspace, by the overlaying
characters. This sets up the correct alignment on the terminal.
3. An underscore in the overlaying line must be used to place a blank
into the corresponding position of the current line. Thus, an
underscore cannot be placed (or replaced) in a line.
4. OVERLAY should be used with care on lines containing underscored words or other compound characters.

has been overlaid.
