TECO-64 - Deletion Commands

The following summarizes the text deletion commands, which permit deletion of single characters, groups of adjacent characters, single lines, or groups of adjacent lines.

Delete commands

Command	Function
D	Delete the first character following the current position of dot.
nD	Execute the D command n times. If n > 0, the n characters following dot are deleted. If n < 0, the n characters preceding dot are deleted. If n = 0, the command is ignored.
-D	Equivalent to -1D.
m,nD	Equivalent to m,nK.
n:D	Same as nD but returns -1 if the command succeeds, and 0 if the command failed because the range of characters to be deleted fell outside the edit buffer.
n@FD/text/	Search for the nth occurrence of text and delete it. n may be negative.
@FD/text/	Equivalent to 1@FD/text/.
@FR//	Equivalent to -nD where n is the length of the last insert, get or search command. See the description of the @FR/text/ command for more details.

Kill commands

Command	Function
K	Deletes the contents of the buffer from the current position of the buffer pointer through and including the next line terminator character.
nK	Executes the K command n times. If n is positive, the n lines following dot are deleted. If n is negative, the n lines preceding dot are deleted. If n is zero, the contents of the buffer from the beginning of the line on which the pointer is located up to the pointer is deleted. It is not an error if more lines are specified than occur when a boundary of the edit buffer is encountered.
-K	Equivalent to -1K.
m,nK	Deletes the contents of the buffer between pointer positions m and n. dot moves to the point of the deletion. The ?POP error message is issued if either m or n is out of range.
HK	Deletes the entire contents of the buffer.
nFK/text/	Search for the nth occurrence of text, and delete all characters in the edit buffer between the initial position before the search, and the final position after the search.
@FK/text/	Equivalent to 1FK/text/.
