indents appropriate for LISP code, and the (, ), {, }, [[, and ]] subcommands
are modified to act appropriately for LISP.

-r[File] Recovers a file after a vi editor or system malfunction. If you do not
specify the File variable, the vi editor displays a list of all saved files.

-R Sets the readonly option to protect the file against overwriting.

-tTag Edits the file containing the Tag variable and positions the vi editor at
its definition. To use this flag, you must first create a database of function
names and their locations using the ctags command.

-v Enters the vi editor in the verbose mode.

-wNumber Sets the default window size to the value specified by the Number
variable. This flag is useful when you use the vi editor over a low-speed line.

-yNumber Overrides the maximum line setting of 1,048,560 with any value greater
than 1024. You should request twice the number of lines that you require because
the vi editor uses the extra lines for buffer manipulation.

+[Subcommand] Carries out the ex editor subcommand before editing begins. If you
do not specify the Subcommand variable, the cursor is placed on the first line
of the file. This + flag is incompatible with the -c flag. Do not specify both
flags at the same time.

vi General Subcommand Syntax

Use the following general syntax to enter subcommands:

[Named_Buffer] [Operator] [Number] Object Note Square brackets indicate optional
items.

[Named_Buffer] Specifies a temporary text storage area.

[Operator] Specifies the subcommand or action; instructs the vi editor.

[Number] Specifies either the extent of the action or a line address as a whole
number.

Object Specifies what to act on, such as a text object (a character, word,
sentence, paragraph, section, character string) or a text position (a line,
position in the current line, screen position).

Counts before Subcommands

You can put a number in front of many subcommands. The vi editor interprets this
number in one of the following ways:

  o Go to the line specified by the Number parameter:
    5G

    10Z

  o Go to the column specified by the Number parameter:
    25|

  o Scroll the number of lines up or down specified by the Number parameter:
    10Ctrl-U

    10Ctrl-D

vi Editor Subcommands

Use the subcommands to perform these kinds of actions:

  o Moving the cursor
  o Editing text
  o Manipulating files

  o Paging and scrolling
  o Searching for patterns
  o Marking a specific location in a file and returning
