Viewtable窗口可以让你以表格形式输入数据,可以定义变量、设置属性,如name、length和 type(character or numeric). SAS 企业向导模块,aWindowsonlyapplication,has a data entry window that is very similar to the Viewtablewindow.As with Viewtable,you can define variables and give them attributes. ...
do i=1 to dim(zero); if zero{i}=. then zero{i}=0; end; *是种省略写法,’{}’,’()’均可,dim返回数据的维度,表示数据集中所有的数值型变量的个数。也可以把_numeric_替换成具体的变量。 对字符型变量,用法类似。 array char{*} _char...
