Re your two questions of May 23:
1) It has long been a feature of MACLISP that <cr> is a classed
   as a "control-character", and hence invisible (unless "slashed")
   to the SYMBOL parser.
2) As for display-style rubout processing - there is some problem
   in that TOPS-20 does not provide a general protocol for cursor
   control on "glass" terminals.  Probably the best thing to do is 
   to use RDTTY for input which will allow rubbing-out to be done
   by the 20X system, but which will likely require (SSTATUS LINMODE T).
