各位论坛大神：
今天我用SAS Studio读取excel里面的数据，直接用excel的第三行值作为变量名，但是出来的变量名竟然是带空格和特殊字符的。请大神们指教一下。log如下：

1          OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;
55         
56         proc import datafile="/home/weix10/08_DM support/B7601003 AE and condrug.xlsx"
57             out=raw_ae dbms=xlsx replace;
58             getnames=yes;
59             range="AE$B3:";
60             *guessingrows=30000;
61         run;
