When SAS processes a data step it has two phases.
Compilation phase and execution phase.
During the compilation phase the input buffer is created to
hold a record from external file. After input buffer is
created the PDV is created. The PDV is the area of memory
where sas builds dataset, one observation at a time. The PDV
contains two automatic variables _N_ and _ERROR_.
