No promises, but here's a thought.
Since retained variables get processed differently than nonretained, the
logical order of variables in the PDV is influenced by whether the
variable is retained or not. (4 sections: character vs. numeric, and
retained vs. nonretained). All variables regardless of position must
have a keep/drop flag. But retaining a variable in part determines its
location in the PDV.
That said, to us outsiders it's all tea leaves.
