         Parameters:  [#lines {1} | begin-line#[end#] RANGE]
  
 This command  has  two forms.  The first form deletes a total of
 "#lines" lines, beginning with the current line. 
  
 The second form (using the parameter "RANGE" or "R") deletes the
 range of lines specified by "begin-line#"  through  "end#"  from
 the file.   If  "end#"  is omitted, only 1 line is deleted.  The
 "begin-line#" may be signed + or  -,  relative  to  the  current
 line, and "end#", relative to "begin-line#". 
  
 The first line after the deleted line(s) becomes the new current
 line.   If  all lines to the bottom of the file are deleted, the
 message "BOTTOM" is printed, and the current line is set to  the
 bottom line.
