上述代码中,%macro和%mend之间定义了一个宏,宏名为create_month_macro,接受两个参数start_date和end_date,分别表示起始日期和结束日期。在宏中,使用%sysfunc函数结合intnx函数来计算起始日期和结束日期之间的月份个数,并使用%do和%end来循环生成每个月份的宏变量current_month。最后,使用%put语句将每个月份打印...
You can use theSYMPUT routineto create a macro variable and to assign to that variable any value that is available in the DATA step. When you use the SYMPUT routine to create a macro variable in a DATA step, the macro variable isnot actually created and assigned a valueuntilthe DATA step...
Be careful.You cannot create a macro variable with CALL SYMPUT and use it in the same DATA step.Here’s why. When you submit macro code, it isresolvedby the macro processor, and thencompiledandexecuted.Not until the final stage— execution—does SAS see your data.CALL SYMPUT takes a data...
