I've found another error in the data class selection routines which means
that datasets have been converted but not assigned the correct data class.
What is the quickest way to reassign a data class (or storage class come to
that).  Do I have to CONVERTV to NONSMS and then CONVERTV to SMS again or
is there some quicker method.
