SAS宏未运行

Question

我似乎无法弄清楚为什么我的宏不会多次运行。我得到的错误是这样的：“在将来的SAS版本中，带引号的字符串后的标识符的含义可能会更改。建议在带引号的字符串和后续标识符之间插入空格”。我明白了...我在某处有一个混乱的报价..但我在任何地方都找不到。.请帮助。这是代码：

proc datasets lib=work nolist kill; run; quit;
libname tw '';
libname jrd   '';

options varinitchk=error;

  by inquiry_id quote_time_dt quote_time;
run;

data quotes;
  set x0; 
  by inquiry_id quote_time_dt quote_time;
  if first.inquiry_id;
  year =year(quote_time_dt);
  count =1;
run;

data transactions; 
  set dataset_name;
  year = year(execution_time_dt);
  count = 1;
run;
