The above does work, and I had tried it, the problem is I can't figure
out a way (good or bad) to print out the result. Here is what I am doing
now, but it doesn't validate the if:

(I've looked at gcc java's parse.y, a very complex example. It looks
like it stores everything in various structures. In my case I wouldn't
mind reading and validating an entire file at a time. Are there any
examples less advanced? 
I also tried 
sprintf($$,"some string %s", $2)... Not sure if this worked or not.

             printf(string,blank,$1);
             
           }
         }
         ;
