Hi Ashwin,
   THanks you for your quick response. When I said "fix" I meant I wanted
to  play with the instructions that are already generated. It is for
getting some results. Can you please tell me a little specificially
where in the frags are the instructions stored and the format they are
stored?

Thanks,

Balaji V. Iyer.
