Hi Ulrich,


In SableCC, the FIRST set is computed using the Grammar.computeFirst()
method in file src/org/sablecc/sablecc/Grammar.java.


You should investigate using Eclipse (http://eclipse.org) to browse the
source code of SableCC, as Eclipse provides many useful features for
understanding Java source code, such as visual class hierarchy,
declaration finder, etc.


Note that you can ask SableCC related questions on the SableCC mailing
list at http://sablecc.org/lists/control/listinfo/sablecc-user/ .


Have fun!


Etienne
