I have placed a new version of Berkeley Yacc in ~ftp/pub/byacc.tar.Z
on ucbarpa. The internet address of ucbarpa is 128.130.32.11. The new
version fixes all but one of the bugs reported to me so far (at least I hope
it does).
When reporting bugs, please, if at all possible, include small examples
demonstrating the problem.
An extra parser skeleton included with the new version. It is the parser
skeleton for the new and improved version of Berkeley Yacc. I would
appreciate comments concerning the new parser skeleton.
Yours truly,
Bob Corbett

I have placed a new version of Berkeley Yacc in ~ftp/pub/byacc.tar.Z
on ucbarpa. The new version is an extensive modification. There are many
new features. The major improvement is that it is far more compatible with
AT&T Yacc. Because of the extent of the changes there are certain to be
many new bugs. The internet address of ucbarpa is 128.32.130.11.
For those who do not yet know it, Berkeley Yacc is a public-domain
Yacc-compatible parser generator.
Yours truly,
Bob Corbett

I have fixed several bugs in the new version of Berkeley Yacc. The copy of the source in ucbarpa:~ftp/pub/byacc.tar.Z has been updated. For those who already have copies of the new version, a copy of the diffs appears at the end of this note. Special thanks to Dave Gentzel and Bill Sommerfeld for pointing out numerous bugs.

I have placed a new version of Berkeley Yacc in ~ftp/pub/byacc.tar.Z on
ucbarpa (IP address 128.32.130.11). I added a new option, -r, that
causes Berkeley Yacc to put the read-only tables and the rest of the
generated code in separate files. The option is intended to eliminate
the need for :yyfix.
Yours truly,
Bob Corbett
