Sas 宏变量不能用下划线解析,sas,sas-macro,Sas,Sas Macro,在使用下划线时，试图在宏定义内解析宏变量时出现问题。我想保持这里的命名约定，但需要宏变量来解析。我错过了什么 %macro mymacro(dd=,mm=,yy=,dnr=,dma=); . . . %if dnr = 1 %then %let dnrname=est; %if dnr = 2 %then %let dnrname=cen; %if dnr = 3 %then %let dnrname=mtec; %if dnr = 4 %then %let dnrname=pac; %if

%如果dnr=1%，则%let dnrname=est


这就是问题所在
dnr
从不等于
1
。您缺少与号。
%如果dnr=1%，则%let dnrname=est

这就是问题所在
dnr
从不等于
1
。你错过了符号
