SAS: assign a quantile to a macro variable

Question

In SAS, how can I assign the 97.5% quantile of the normal distribution to the macro variable z?

---

Not working 1

%let z = quantile("normal", 0.975); 

Not working 2

%let z = %sysfunc(quantile("normal", 0.975));

Answer 1

Macro does NOT like unnecessary quotes:

%let z = %sysfunc(quantile(normal, 0.975));
