1 DELETE
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.
2 /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
