DELETE
3-20. DELETE COMMAND
3-21. Purpose.
The DELETE command is used to delete lines and/or character strings from
the WORK file.
3-22. Form.
The form of the DELETE command is
D[ELETE][Q] [rangelist]
For example,
DELETEQ 1/10
3-23. Description.
The DELETE command will delete complete lines, specific character strings
from a line, or the entire contents of the WORK file. If no rangelist is
specified, EDIT/3000 deletes the line in which the pointer is located. A
rangelist that specifies a startline/stopline pair deletes these
lines and all lines in between. A rangelist that specifies a
startline,stopline pair deletes only these two lines. A rangelist that
specifies positions within lines, separated by a slash, results in the
deletion of all characters contained be- tween these two columns,
including any lines that fall between the two positions.
When the DELETEQ form of the command is used,EDIT/3000 does not display
the lines deleted. Instead, a message is displayed showing the number of
lines deleted. For example,
/S SHORT;T EDIT3;DQ 1/4
NUMBER OF LINES DELETED = 4
/E
CLEAR? Y
In interactive session, you may terminate an active DELETE command at any
time by typing CONTROL Y on the terminal.
3-24. Limitations.
WORK file contents removed with a DELETE command are lost. When a DELETE
ALL command is entered (deleting the entire WORK file), EDIT/3000 will
ask if it is OK to clear, thus confirming your intent.
NOTE EDIT/3000 does not list the lines removed when the DELETE ALL
command is used.
The DELETE command operates between LEFT and RIGHT margin values unless
the rangelist specifies lines (without column numbers). In this case,
entire lines are deleted, and the DELETE command ignores SET LEFT and SET
RIGHT commands. See paragraph 3-92 for a discussion of the SET command.
