... also there is a limit for BY-lists for sorting: if the variables are "too
far at the right side", they will be ignored for sorting.

Thema: Re: RE(ason for): Ordering variables in data step
There may be a new tendency to send sas data sets to certain US federal
regulatory agencies as part of typical submissions in place of paper
listings. It helps if the data set has a structure similar to what one
would find on a listing (trt, site, patno, visit, etc.) so, at minimum,
a reviewer can use SAS viewer to look at the data.

"var1-numeric-varN", and "var1-character-varN" works as intended, as the
selection depends on the position in the pdv.
