Hi Sam,

When I dealt with semantic predicates I put the unique prefix part of the rule into a predicate.
I put the predicate on those rules that ANTLR said were ambiguous.

For example:

| (binarySelector) => binarySelector variableName
| (MINUS MINUS) => specialBinarySelector variableName

I found out most of the information on predicates by googling "ANTLR Semantic Predicates"

Rgs, James.
