         Parameters:  [to-column#]
  
 Joins  the text from the next line to one space after the end of
 the current line.  The parameter "to-column#" may  be  specified
 (no  leading  space)  to join the text in a particular column of
 the current line. 
  
 The text is copied onto the current line, so the line  following
 the current line is not affected.
