Hello,

Thanks for you inputs. I want to let you know that I started a bit of
STATA programming which essentially involves very basic coding for
cleaning the data and a bit of recursions. Frankly speaking, I believe
my JAVA knowledge is of no use for STATA programming. So, I request
you to please suggest me as to how should I learn coding in STATA from
scratch.

Thanks a lot.
Mayank
