[antlr-interest] Accessing a return value ...

[Anthony Youngman]

Thanks. Sorry - I missed it - I didn't notice you'd rewritten my code
since it looked so similar to my code :-)

Cheers,
Wol

programst { int val = 0; } :
  #(PROGRAM (IDENT)? statement_list END) 
| #(SUBROUTINE (IDENT)? (val=formalargs)? statement_list END) 
| #(FUNCTION (IDENT)? (val=formalargs)? statement_list END) 
{
	// do stuff with val...
}
;

Notice the 'val=formalargs' in the above... Just plain old assignment,
only
caveat is getting the order right if you also use a label then it
becomes:

  val=lbl:formal_args

Cheers,

Ric
