Answer 1

You can do it without macros at all, if you don't mind asking for datasets that may not exist, and have a reasonable bound on things.

data want1 want2 want3 want4 want5 want6 want7 want8 want9;
if _n_ le 2.5e5 then output want1;
else if _n_ le 5e5 then output want2;
else if _n_ le 7.5e5 then output want3;
... etc....
run;

Macros would make that more efficient to program and cleaner to read, but wouldn't change how it actually runs in reality.
