a=sum(_c1_, _c2_, _c3_)
之前这个_C1_什么的都是没定义的，我想应该有特定的含义吧
网上搜了一下，只有_n_的意思, 之前自己上课也学过，但是没见过这个_c1_什么的 |

Before SAS assigns the column display name as shown in COLUMN and Define
statements, SAS give all the columns automatic names such as c1_, _c2_.....
_cn.... .
Then SAS replace these automatic names with the display names. |
