Hi All,    I am stuck in converting the transition semantics in Haskell. Please let me know how to define memory data types in Haskell( like we define pointer in C). Prompt help would be greatly appreciated.

I'm sorry, but I can't understand your question. Do you want to interface with C or another language using the FFI interface? Or are you asking about a feature of pure Haskell code? If you're asking about pure Haskell, I'm going to guess the answer is "you can't", or use eg. IORef, MArray, for impure types. (But I discourage their use) If you give us more information about what problem you are trying to solve, we can be of more help. Luke
