         Parameters:  [begin-line# [end#] {current-line}]
  
 Copies  the  range  of  lines specified by "begin-line#" through
 "end#" after the current line.  If "end#"  is  omitted,  only  1

 The "begin-line#" may be signed + or -, relative to the  current
 line, and "end#", relative to "begin-line#".
