标题[问题] sas 认证题库问题

感谢上一篇板主的提示，虽然第一题还是觉得很奇怪 orz
但问题还是排山倒海而来阿
data work.totalsales (keep=monthsales{12});
set work.monthlysales (keep=year product sales);
array monthsales {12};
do i=1 to 12;
monthsales{i}=sales;
end;
run;
这个存在syntax error，不过我找不出来（倒地）
data work.totalsales;
set work.monthlysales(keep=year product sales);
retrain montnsales {12};
array montnsales {12};
do i=1 to 12;
monthsales{i}=sales;
end;
ent+1;
monthsales{ent}=sales;
run;
这个也是个syntax error，不太确定是哪里出错 orz
data work.january;
set work.allmonths (keep=product month num_sold cost);
if month='jan'then output work.january;
sales=cost*num_sold;
keep=product sales;
run;
这个是因为最後的keep statement有问题吗?
感谢大家的讲解跟赐教 orz
