I'm a bit curious, as someone who knows how to program in SAS but didn't
learn the book way so doesn't know terminology. What does PDV really
exactly mean? To me, it would mean path from the variables in the code and
input dataset to the output dataset. Then, automatic variables [eg _N_, in=
variables, etc.] wouldn't really be in the "PDV" since they are not getting
written out... Does PDV actually mean the internal temporary memory
structure that exists in between the code/input data and the output data?
