我的SAS程序正常运行时遇到问题.我从我的文件中获取数据的方式有问题,而且它弄乱了里面的一切.这是我的代码部分搞乱了:
data Stocks;
infile 'location of file.txt';
input @1 Stock : $4.
@5 PurDate : mmddyy10.
@15 PurPrice : dollar6.1
@21 Number : 4
@25 SellDate : mmddyy10.
@35 SellPrice : dollar6.1;
TotalPur = Number * PurPrice;
TotalSell = Number * SellPrice;
Profit = TotalSell - TotalPur;
run;
proc print data=Stocks;
var Stock PurDate PurPrice Number SellDate SellPrice TotalPur TotalSell Profit;
run;

每次我运行它,它告诉我,"注意:每行的数字无效".它会关闭所有数据(例如日期值和诸如此类的东西).我知道我的计算变量不起作用,因为它们依赖于未正确获取的Number数据.我很欣赏人们可以给我的方向.
摆脱所有的冒号(:).
然后在数字4之后添加一个点(.)以表明它是一个信息.
这应该够了吧.
