Great fun, then.
Since you have to SORT the data, into two sequences, extend the records to include a "count" field (at the beginning for variable-length records, at the end for fixed-length records) which is large enough for the maximum possible people dealing with the same office. Make it a factor of 10 larger, just in case there's a bank merger :-)
SUM on the count.
For the JOIN use UNPAIRED,F1,ONLY.
In the Maintask of the JOINKEYS, use INCLUDE= for the count being one, and have a BUILD on INREC to drop off the count you added earlier.
If you then need some other order than first-surname, you can SORT in the Maintask as well.
