Convert a number into words
--------------------------------------------------------------------------------
Description : This program converts a number into words.
It works only(!) for numbers less than 100 crore, though this
limit can be extended using the same logic.Can be used in
billing programs and the like, with a few minor changes (like
adding "only" at the end) The program is shorter other such
programs and the logic is really elegant.
