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.

1    /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
