Here you can find what you want:
http://www.cocolsoft.com.au/dgram/dgramh.htm (i'm not sure for the source files)

If you want to do i t yourself, check out the following resource for grammars:
http://www.cobase.cs.ucla.edu/pub/javacc/
for the parser generator (the best one can get) at
http://www.metamata.com/JavaCC/
You may also want to use the http://www.cs.purdue.edu/jtb/ product that generates even more code for you if you want to build something more than a parser.

I couldn't find Pascal grammar for JavaCC, however, I think you can easily make it yourself using one of the examples.

Cheers,

Oberon is an extension of Pascal, and there is a JavaCC grammar for it, just modify a bit.

Sorry for the delay, time zones, etc.

JavaCC takes as input a formal description (line BNF) of a language, called grammar. The it generates compilable (by JDK) code that recognizes text written in the language the grammar describes.

Furthermore, JTB  additionally generates an expression (program) tree builder that helps you automate the semantics implementation for a particular program.

The process is quite common, like yacc and lex for C. One generates the parser, the other, the lexical analysis. You may be need only the parser.

To summarize, you create the input for JavaCC, you use the code generated from JavaCC. If you need to, use JTB for more sophisticated programming.
