Answer Posted / cutepa1
To the above answers I like to add a bit of information that
PDV has even more automated variables such as
FIRST.<by-group-variable>, LAST.<by-group-variable>, _END_,
...etc, along with _ERROR_ and _N_ where each has got its
own significance to have a control over the execution of a
SAS Program.
