在导出文件期间检测到打开代码语句递归 [英] Open code statement recursion detected during exporting a file

问题描述

我尝试在 SAS 中导出文件，但我得到检测到打开代码语句递归".错误.由于我根据日期导出多个文件，因此我根据提示日期定义为宏变量，因此我想将我的文件命名为使用此变量导出，但它不起作用.如果有人帮助我，我将不胜感激.

I try to export a file in SAS but I get "Open code statement recursion detected." error. Since I export more than one files depending on date I define as a macro variable based on the prompt date, I want to name my file to be exported with this variable but it does not work. I would really appreciate if anyone helps me.

rep_date = 30APR2015:00:00:00
 Outfile = work.A042015.sas7

%let var = CATS("A",MONTH(DATEPART(&rep_date)),YEAR(DATEPART(&rep_date)));
data WORK.&var(compress=yes); 
set WORK.have;
run; 

推荐答案

宏变量只是字符串.所以如果你想在宏代码中执行函数，你需要将函数包装在 %SYSFUNC() 宏函数中.

Macro variables are just strings. So if you want to execute functions in macro code you need to wrap the function inside of the %SYSFUNC() macro function.

%let rep_date='01JAN2015:01:23'dt ;
%let dsname = A%sysfunc(datepart(&rep_date),monyy6);
data &dsname(compress=yes);
  set have;
run;
