Mystery sum with placeholder digits
As for a review of the code I would suggest to avoid acronyms (also recommend, as @200_success did, to better indent the code, in case this is how your code is indented).

As for the solution, I would strongly avoid brute force ones. This is a cryptarithmetic problem and, if you work only on base 10, you have 10! possible assignments, but if you generalize (for any base) then the problem is NP-complete. I would suggest to look for solutions for cryptarithmetic problems (usually they are described on texts/sources on AI).
