想请教大家一下#116
虽然知道答案是syntax error

想跟大家讨论一下
我自己认为是retain 不能用 retain monthsales {12}
[程式范例]:

doi=1 to 12;
monthsales{i}=sales;
end;
ent+1;
monthsales{ent}=sales;
run;
The data set named WORK.MONTHLYSALES has one observation per month for
each of five years for a total of 60 observations.
Which one of the following is the result of the above program?
