Are you calling getDxByIndex within getDxByIndex? If you are, that may be
considered recursion, and I believe it is not allowed in the Palm OS. If
you are calling the same function name from another class, that should be
ok. If that is not the problem, the only other suggestion is to make sure
other variables are not overwriting your call on the stack (make sure you
are using pointers correctly & within their allocated memory space).
