/CONFIRM (D)

    Instructs LSE to prompt you for a confirmation at each occurrence
    before performing a substitution. If you specify the /CONFIRM
    qualifier, LSE highlights each occurrence of the search string
    located by the search and prompts you for an action.

    o  YES instructs LSE to replace this occurrence.

    o  NO instructs LSE not to replace this occurrence but to proceed
       with the command.

    o  QUIT ends the command without replacing this occurrence and
       stops the SUBSTITUTE operation.

    o  ALL replaces this occurrence and all remaining occurrences
       without further prompting.
