感謝上一篇板主的提示，雖然第一題還是覺得很奇怪 orz
但問題還是排山倒海而來阿
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;
這個存在syntax error，不過我找不出來（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;
這個也是個syntax error，不太確定是哪裡出錯 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;
這個是因為最後的keep statement有問題嗎?
感謝大家的講解跟賜教 orz
