Should read `2*16+10+5 (#2Fh)' and `#2313410002F02DCCh' respectively.


   I ftp'd sass23.tar.Z from calvin.stanford.edu (I think) and
unpacked it. It wouldn't compile with gcc nor cc (SunOS 4.something),
nor would using bison instead of yacc or Gnu lex instead of /bin/lex
help. Inserting an "extern YYSTYPE yylval" into scan.c (the lexified
scan.l) made it pass.

   Later examining the code revealed that you have to specify -xc to
get a code object. You already know what -x by itself will give you.
:-)

And oh, there doesn't seem to be any provision for arithmetic, i.e.

	da	endpt-startpt

won't work. Another annoyance it that it blocks/hangs whenever an
error is encountered. Is this an old version?
