I am learning SAS. I tested a function shown below, the function is to find the larger value of two integers. However, it kept reporting errors shown below. Could someone please help me with that? Thank you. %macro max(dat);
data _null_;
set &dat;
if x >= y then put x =;
else put y =;
%mend max;
data temp;
input x y;
cards;
7 3
;
run;
proc print data=temp;
run;
%max(temp); 2633 %max(temp);
NOTE: Line generated by the invoked macro "MAX".
1 data _null_; set &dat; if x >= y then put x =; else put y =;
