Bison games

This is an extremely simple question, but it needs to be addressed and I
have not found a proper answer. I'm sure you all know it though.


What I want to do is create while() { ... } and if() { ... } else { ... }
syntax. How can I do this with Bison? I have a working grammar that
processes the single lines fine. I do not do anything past that.


A simple example would be great. I have read the epaperpress one but i just
don't get it.
Thanks!
[Yacc and its relatives make one pass through the input. If you want to
do something like a loop, you either have to arrange to keep feeding the
input to yacc each time through the loop (not recommended) or first
translate into something easy to interpret like RPN or a parse tree
and then write an interpreter that runs what you parsed. -John]
