I have been using Coco/R recently and have found it to be quite easy to
generate scanner/parsers using it. The scanner and parser specifications
are in the same file, which I find to be a great improvement and the parser
is specified via extended BNF. Coco/R generates a reasonably efficient
scanner and a recursive decent parser. It is quite easy to annotate the
parser spec with arbitrary actions that are performed upon recognition.


There are several versions of Coco/R available depending on your
linguistic tendencies:


    C: ftp://cs.ru.ac.za:/pub/coco/cocorc04.zip
    Modula-2: ftp://neptune.inf.ethz.ch:/Coco/
    Oberon: ftp://neptune.inf.ethz.ch:/Oberon/Examples/Coco/


I am also enclosing a post by Pat Terry which gives you his slant
on things.
