问题

我想解决的问题是在一个DO循环中使用RANUNI，并调用生成10个样本，每个样本大小为15，随机变量的值是介于10和20之间的数字。由于我必须使用调用例程，我无法获得介于10和20之间的变量。在拥有以下代码之后，我生成了0到1之间的值。

到目前为止，我已经做了这个-

DATA seven;
DO i=1 TO 15;
 CALL RANUNI(2020, x1);
 CALL RANUNI(2020, x2);
 CALL RANUNI(2020, X5);
 CALL RANUNI(2020, X6);
 CALL RANUNI(2020, X7);
 CALL RANUNI(2020, X8);
 CALL RANUNI(2020, x3);
 CALL RANUNI(2020, x4);
 CALL RANUNI(2020, x9);
 CALL RANUNI(2020, x10);
 OUTPUT;
END;
PROC PRINT DATA=SEVEN NOOBS ;
RUN;
```

I want a solution to the problem where I have to use the RANUNI in a DO loop and call, and generate 10 samples, each of size 15, the value of the random variable is a number between 10 and 20.  
Since I have to use Call Routine, I am not able to get variables between 10 and 20. After having the following code, I am generating values between 0 to 1.  

So far I have done this-

DATA seven;
DO i=1 TO 15;
CALL RANUNI(2020, x1);
CALL RANUNI(2020, x2);
CALL RANUNI(2020, X5);
CALL RANUNI(2020, X6);
CALL RANUNI(2020, X7);
CALL RANUNI(2020, X8);
CALL RANUNI(2020, x3);
CALL RANUNI(2020, x4);
CALL RANUNI(2020, x9);
CALL RANUNI(2020, x10);
OUTPUT;
END;
PROC PRINT DATA=SEVEN NOOBS ;
RUN;

使用 [`CALL STREAMINIT`](https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/lefunctionsref/p0gw58qo85qp56n1kbpiz50ww8lv.htm) 例程与 [RAND()](https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/lefunctionsref/p0fpeei0opypg8n1b06qe4r040lv.htm) 函数

```sas
data want;
call streaminit(2120);

do sample=1 to 10;
	do obs=1 to 15;
		rand=rand('uniform', 10, 20);
		output;
	end;
end;

drop obs;
run;

sample    rand
