   Hi,   
      
   Writing an assembler, I'm stuck with ambiguities with my syntax. The   
   syntactic analysis is a simple LL(1) recursive descent parser. Here is   
   the issue (look at the "(" as a FIRST)   
      
   	LDA (data),Y		; #1 Indirect address indexed by Y   
      
   index	EQU 123   
   	LDA (index-1)*3,Y	; #2 Absolute address indexed by Y   
   	LDA 3*(index-1),Y	; Equivalent but non ambiguous   
      
   An except of the grammar :   
      
   line	= mnemonic oper   
   oper	= "(" addr ")" "," "Y"   
   	| addr "," "Y"   
   addr	= ["+"|"-"] term { ["+"|"-"] term }   
   ... etc   
      
   The "(" of the _oper_ rule conflicts with the one from the _addr_   
   expression. Do I get this right ?   
      
   Is there a work around ?   
      
   Thanks for your time.
