The DELETE (abbreviated D) command deletes the lines specified by the range.

Format: DELETE [range] [/QUERY]

If you do not specify the range, the default is the current line.

Additional information available:

/QUERY

Format: /QUERY

When you use the QUERY (abbreviated /Q) qualifier, EDT prompts you with a
question mark (?) to verify each line to be deleted.

Responses are:

    Y   Yes, delete this line
    N   No, do not delete this line
    Q   Quit, do not delete any of the remaining lines in the range
    A   All, delete all the rest of the lines
