代码语言:txt 复制 %macro create_macro_variable(var_name, var_value); %let &var_name = &var_value; %mend create_macro_variable; 调用宏:使用%create_macro_variable语句调用宏,并传递参数(如果有)。例如,下面的代码调用了上述定义的宏,并创建了一个名为"my_variable"的宏变量,其值为"Hello, World!
默认去双尾空白,其他效果和symput一样 随后一个参数表示宏储存的位置'L'=local 'G'=global TheSYMPUTroutine and theSYMPUTXroutinecan only create a local macrovariable if alocal symbol table already exists.If nolocal symbol table exists when the SYMPUT routine or SYMPUTX routine executes,it will creat...

本篇论文提供了两支主要的SAS MACRO程序;%Homopoly和%Model_Selection分别会在下个两章节中介绍.程序%Homopoly是用在建立多项式数据文件,而%Model_Selection则是用来提供SAS模型筛选后的总结数据,报表格式是仿照表11.8 Montgomery制作的.读者可以很容易复制到其他的分析.为了要编写程序,我同时提供了20支工具程序,读者...
