[antlr-interest] Re: generated code not compilable - with paramet ers.

[praveen_c]

This rule( TEXT ) is referred in some other rule with a slightly 
different twist ( which is why I had the boolean in the first 
place ). I wanted to reuse the same rule without having to code 
another one again.

I could use an instance variable, but I wanted to stay away from it 
because then I will have to make sure that I set/reset the instance 
variables at various points. I can see it getting a bit complex.

I'll go with copying the rule into the place where I was referring to 
this one. If you guys can think of other alternatives please let me 
know.

Thanks,
Praveen.
