Explanation

A Natural HISTOGRAM statement reads a descriptor, returning one loop cycle per unique value. Starting from '1234', there are four distinct descriptor values present: '1234 AAAA 12', '3456 CCCC 14', '6879 DDDD 17', and '7625 EEEE 21'. The duplicate '1234' record does not produce an extra iteration.
