Hi,


I am developing a FORTRAN information extractor system as an assignment.
I would like to have Lex/Yacc grammar for this. I have already seen
FORTRAN 77 subset parser (ftn) by John Levine, and I was wondering if there
is a more complete version available _with_ lex grammar. Email is
preferable.


Thanks a lot,
Anil
[I would be astonished if you ever found a lex scanner for Fortran. It's
not at all suitable. You can find a full f77 parser in f2c, the Bell Labs
Fortran to C translator. It uses a yacc parser and a hand written lexer,
just like I did. -John]
