An index? I'm not sure what you mean. One thing I have thougth of is as well as doing a count of the sort codes building a hash structure with the row number and the sort code - is this what you mean? Out of curiosity what is "too large" a hash? (coming from a web background where i'm used to trying to make everything as small as possible)

Thanks for your quick replay too
