%LET statements are never part of a DATA step. You might as well have coded:
%let switch = N;
%let switch = 'Y';
%put &switch;
data _NULL_;
if rand('UNIFORM') > 0.3 then do;
end;
run;
That reflects what your program is actually doing. However, the good news is that there are interfaces between a DATA step and macro language. You could instead code:
%let switch = N;
data _null_;
if rand('UNIFORM') > 0.3 then call symput('switch', 'Y');
run;
%put &switch;
Two problems: 1 you change it from N to 'Y' (why do you add quotes for Y?)
2 You use %let let in a datastep, when you should use call symput
What condition do you really want to use? Surely, not just randomly like shown in your code.
