Re: READ only first and last obs. The first SET statement reads the first observation from the source table as you're used to it. The OUTPUT statement then writes this row to the target table. The second SET statement then uses direct access via keyword point=_nobs_. This reads the observation number stored in _nobs_ from the source table - and ...would be or even what the last variable in the list would be when the code was written. In the above example for &pggrp = 016_017 the string FIRST.&&KEY&KEYCNT resolves to FIRST.OCC1. Since there are three variables in the BY statement, &KEYCNT is 3, and &KEY3 is OCC1.

The program shows that you can find the first day of the previous month, the last day of the previous month, the middle of the previous month, or an anniversary of the specified date.
