You conducted a survey and the responses to the five questions were coded as A B C D E .A.Using the following eight lines of data,write a SASA data step to read these data and create five variables (QUES1,QUES2,QUES3,QUES4,QUES5)。Remember that these must all be charactered variables(since the values are letters)and there are no spaces between the values so you must use column input .Next ,generate frequency distributions for each of the five questions .omitting cumulative statistics from the listing .
The data is as follows

ABCDE

AACCE

BBBBB

CABDA

DDAAC

CABBB

EEBBB

ACACA

刚刚开始学习SAS。搞不懂怎末弄。
就是求A B C D E 的频率，但是不知道怎末用QUES1---QUES5表示，
这个题目建议是用COLUMN INPUT，具体应该怎末输入呢？
不要求COUMULATIVE SATISTICS，但是用到proc freq data=test 去不掉呢
thank you so much
