You can find the complete grammar file and a sample of valid input here:

- <http://64.142.14.4/~rschulz/TSTP.g>
- <http://64.142.14.4/~rschulz/MED001+0.ax>

The grammar has changed a bit since I wrote the original message here, 
but the problems remain.


I don't know how to use the debugger, and there appear to be significant 
discrepancies between the ANTLRworks User's Guide 
(<http://www.antlr.org/works/doc/antlrworks.pdf>) and the program as it 
presents itself on my system. When I issue the "Debug..." command, I 
get an alert stating "Compiler Exception: ClassNotFoundException: 
com.sun.tools.javac.Main". I do have a full JDK installed, of course. 
I'm using SuSE Linux 10.0 and Sun's Java 1.5.0_07.
