We want to buy a YACC

[Usenet file owner]

Does anyone know of a parser generator with functionality comparable
to YACC which is either available on VAX/VMS, or available in source
form for us to rehost?  This will be used in a commercial product,
so tools (like GNU's Bison) which restrict such such usage won't do.
Please include price information, if available.

Please send information to:
