Macro variables are just a text substitution mechanism. When you execute SAS code, the value of the macro variable (a text string) is substituted into SAS code (where the macro variable was in the code), and this substitution of macro variable value into the code MUST produce valid working ...

宏程序 %make_empty_dataset.sas 的工作流程为: 首先读取Excel文件 ”SDTM_METADATA.xlsx“ 生成了数据集 _temp。 以varnum将读取到的所有观测排序。 在_temp的基础上生成数据集NULL_,(1)将读取到的观测总数记录到变量vars。(2)将原先Excel中的变量VARIABLE转换为 SAS变量var,并去除空格。(3)将Excel文件中的变...
