I think you may be misunderstanding which I wish to sort. I read in an
array of:
last|first|phone|email|department|...
and wish to sort the array of records by email address or by department
or by first name, etc. The sort function can sort by last name easily
being the first field in the record. I don't wish to sort each record;
but the records based upon different fields in the records.
