如何在 sas 数据步骤中获取当前表名？ [复制]

Question

我需要连接一些表并创建一个带有一些标记的新列，以指示数据来自哪个表。

我有 tbl_202101、tbl_202102 ... tbl_202109。我需要加入所有的，添加一个新的列table_origin，例如，表示各自的表。

DATA FINAL_TABLE;
SET TBL_202101 - TBL_202109;

/* Here I don't know how to identify the current table */
table_origin = CASE 
WHEN *CURRENT TABLE* = TBL_202101 THEN 202101
WHEN *CURRENT TABLE* = TBL_202102 THEN 202102 
AND GO ON...

RUN;

我该怎么做？

    INDSNAME=variable
     
    creates and names a variable that stores the name of the SAS data set
from which the current observation is read. The stored name can be a data
set name or a physical name. The physical name is the name by which the
operating environment recognizes the file.
