The Decus C collection (Decus 11-SP-18) includes a version of Lex that
was written and copyrighted by Charles Forsythe.  (It is distributed with
his permission).  This implements a version of Lex roughly equivalent
to that available on Unix V6 -- i.e., it missing some features of the
current Unix Lex.  (I have the overall responsibility for Decus C
submissions.)

To my knowledge, there is no legal (i.e. public-domain or unrestricted)
version of Yacc available from Decus.  If you find one, I would greatly
appreciate knowing about it so that I can help Decus get it out of the
library.  A public repository of software such as Decus is a cooperative
endevor, and succeeds only if it maintains scrupulous standards of
honesty with respect to the owners of non-public-domain software,
such as Unix.

The above is my personal opinion and should not be construed as representing
the position of either Digital Equipment Corporation or Decus.
