For what it is worth, using a default ANSI lisp
(not a "modern" allegro or a both-cases SBCL etc), it
is annoying to get labels from lisp, in debugging.
In the olden days, label D1 was, in lisp $D1
which could also be typed as $d1.
Now, label %o1 must be typed |$%o1|
which is annoying.
In a both-cases lisp it would be $%o1, which is less
annoying, but $d1 is easier. Maybe I should just set
inchar/ outchar to C and D !!
