[antlr-interest] implementing 'if' and 'while' grammar with actions

[Abhijit Nandkumar Ghonge]

Hi all,

I want to implement parser grammar for 'if' and 'while' statement with actions in it.
My script is :

var1=10
if ( var1 < 9 ) then
var1++
print (var1)
endif

How do I skip the execution of the statements if the "if-condition" is false as in the above case?

I searched for the grammar implementation in the site, but all examples where implementing grammar rules for "if" and "while" without actions in them. I want to embed actions in the grammars.
Please give some pointers to "if" or "while" grammar implementation with actions in it.
Please Help.

thanks,
Abhijit
