[antlr-interest] calling one parser from within another

[Monty Zukowski]

Sure, just call it the same way you call it from a main() program.  
You'll have to pass it the entire SQL string.  Details depend on which 
backend you are using, Java or C++.  Also be sure that you call a top 
level rule, ie a rule that doesn't call any other rules.  It's trivial 
to make a new top level entry rule if one doesn't already exist--

topExpr: expr;
