data one;
input group $ sum@@;
cards;
A 765 B 123 C 564
;
run;
data _null_;
set one;
call symput(group,sum);
stop;run;
what is the result when the program finishes execution?
A. MACRO variable A has a value of 765
B. MACRO variable C has a value of 564
C. MACRO variable GROUP has a value of 564
D. MACRO variable A has a value of SUM
the answer is A.
why not B?
'stop' statement 在这里有影响吗？请指点一二，谢谢！
