All editor commands are entered in the command area and executed by
typing either the carriage return or the keypad + key. The latter will
keep you in the command area while the former will in general return you
to the text area. In the following descriptions variable input of a
particular class will appear in a special typeface e.g. variable
Editor commands are of the form:
[range]C[argument]
where:
- range
- is a range of lines the command is to operate on.
- C
- is a single character indicating a command.
- argument
- is command specific information.
- <none>
- (none; range not specified) Refers to the current line only.
- line
- Refers to this line only.
- line1,line2
- Refers to lines between line1 and line2 inclusive.
- line1;line2
- Same as "," except that current line is updated by
semicolon to line1.
- *
- Refers to all lines in the buffer.
- #
- Refers to any tagged lines.
- <none>
- (none; line not specified) Refers to the current line only.
- number
- Refers to the absolute line number specified.
- .
- Refers to the current line.
- $
- Refers to the last line.
- &
- Refers to the top line on your screen.
- @
- Refers to the defined center line.
- %
- This refers to the current line if you are in the text area
and line zero if you are on the command line.
- /pattern/
- This serves as the line address of the next line
which contains an instance of the specified pattern. The search for
pattern will begin at the current cursor position and will
continue to the end of the buffer. If no match has been found by that time,
the search will wrap around to the beginning of the buffer and continue
looking for pattern from line one. If no match is found in the entire
buffer then an error will be issued.
- ?pattern?
- This serves as the line address of the previous line which
which contains an instance of the specified pattern. The search for
pattern will begin at the current cursor position and will
go backwards through the buffer wrapping around from the first to last line
if necessary. If no match is found an error will be issued as above.
In addition, line addresses may be combined with other line addresses
using the + and - keys to form expressions. You may limit a line address
to lie within the buffer (between 1 and $) by following it with an or-bar (|).
For example
.+5|
Refers to the 5th line after the current line or the last
line if there are less than five lines after the current line.
- .
- (dot) Matches any character.
- ^
- (caret) Matches the null string at the beginning of the line.
- $
- Matches the null string at the end of the line.
- @(number)
- Matches the null string before the numberth character of a line.
- @(.)
- Matches the null string before the current cursor position.
- @(t)
- Matches the null string before the next tab stop.
- [characters]
- Matches any one of the characters enclosed by the square
brackets. (character class)
- [^characters]
- Matches any one character which is not enclosed by the square
brackets. (character class)
- *
- Matches the preceding pattern zero or more times. (closure)
- &
- Only special in the replacement text of a Substitute command.
It will be expanded into the text matched.
- -
- Only special within the square brackets of a character class above.
The syntax character1-character2 is an
abbreviation to mean all characters between character1 and
character2 inclusive. For example [a-z0-9].
