小弟是初学者, 有个问题想请问一下, 如何遍历打印一个表?如下:第一行是列名, 后边的是数据:

inf	client	netd	ftype	db
ELD	ELD	Elders	PDF	ntunix
ELD	IRD	NZIR	PDF	ntunix
ELD	KPM	KPMG	PDF	ntunix
ELD	SCH	Schweppes	PDF	ntunix

我自己写了一些, 可是调试不通, 说不能用do while 语句, 麻烦哪位指点一下应该怎么改, 万分感谢!!

//Open Cursor

%let    cust=%sysfunc(open(work.customerlist,i));  

%let    _Inf   =%sysfunc(varnum(&cust,Inf));  

%let    _Client=%sysfunc(varnum(&cust,Client));  

%let    _Netd  =%sysfunc(varnum(&cust,Netd));  

%let    _Ftype =%sysfunc(varnum(&cust,Ftype));   

%let    _DB    =%sysfunc(varnum(&cust,DB));

%do%while (%sysfunc(fetch(&_Inf))eq 0);            

    %letInf   =%sysfunc(getvarc(&cust,&_Inf  ));   

    %letClient=%sysfunc(getvarc(&cust,&_Client));

    %letNetd  =%sysfunc(getvarc(&cust,&_Netd ));  

    %letFtype =%sysfunc(getvarc(&cust,&_Ftype));  

    %letDB    =%sysfunc(getvarc(&cust,&_DB   ));  

         

    %put    &Inf  &Client  &Netd  &Ftype &DB;  

    run;

                     

%end;

%letrc=%sysfunc(close(&id1)); //Close Cursor
