precedence

Hi

Here is the grammar rules:

ProcessExpression :  EventExpression "->" ProcessExpression

                    | ProcessName ;

Please can you tell me how can I tell to bison that the first rule has the highest precedence than the second one?

I have tried:

%nonassoc PROC

%right "->"

ProcessExpression :  EventExpression "->" ProcessExpression

                    | ProcessName % prec PROC;

But without any result. Thank you.
