Over the years I've written some monster macros that run a whole string
of analyses and produce various outputs. These involve subsetting the
data in more than one way. (Validation samples, data from different
points in time, etc., etc.) To simplify building WHERE statements, I use
%IF <macro-condition #1> %THEN %DO;
WHERE ALSO <macro-driven filter #1>;
%IF <macro-condition #2> %THEN %DO;
WHERE ALSO <macro-driven filter #2>;
This way I don't have to worry about the different syntax of the first
Cheesy? Sleazy? Lazy is more like it. Yeah!

The ATTRIB statement was to change the length of a variable brought in by a SET statement. So combining the RETAIN and ATTRIB statements did not work (the length was not changed by the ATTRIB statement).
