Looking for Fortran Lexer/Parser Information

        I am hand coding a Lexer and a Parser for fortran to help with
code optimization and later on translation into another language
(probably visual basic since it is well supported where I work).


I am looking for some information on lexing and parsing of Fortran.
Mostly in any solutions to the context determined lexing of keywords,
and handling of Common blocks.


Any general grammar information would also be appreciated or any leads
in general.


Thanks in advance for any information,


Cris

hand-coded lexer with a lot of kludges, but it works fine. -John]
