SAS基础题求帮助

题目内容：
You are given a CSV (comma-separated values) file called Political.csv containing state, political party, and age. A listing of the file Political.txt is shown here:
"NJ",  Ind, 55
"CO", DEM, 45
"NY", REP, 23
"FL", DEM, 66
"NJ", REP, 34
a. Write a SAS program to create a temporary SAS data set called Vote. Use the variable names State, Party, and Age. Age should be stored as a numeric variable; State and Party should be stored as character variables.
b. Include a procedure to list the observations in this data set.
c. Include a procedure to compute frequencies for Party.

是不是因为这个数据有符号，所以我用常规做法不对？
DATA Prob315;
INFILE "/home/u62262851/BAN130NBB/political.csv";
INPUT State $ PoliticalParty $ Age;


RUN;
PROC PRINT DATA=Prob315;
RUN;

这是我做的，然后出来完全不对。

谢谢

我知道哪里不对  脑子转过来了--

proc import data="/home/u62262851/BAN130NBB/political.csv"  out=work.Vote dbms=csv replace;
gussingrows=max;
run;

proc content data=work.Vote;
run;
试一下

proc freq data=work.Vote;
Var Party;
run;
