发帖数: 122 | 1 几个小时前考了BASE， 内容几乎可以认为全部来自题库50＋70+123，62题中大概20题
可以认为是变体
错了3题，大概知道错了下面两题／三题 顺便回忆了其它的一些题
1.
data temp;
infile xxx;
date="01feb1980"d
how to generate ship_note in the form “Feb 01, 1980”
A.ship_note=put(date,date9.)
B.ship_note=put(date,date9.,worddate20.)
C.ship_note=put(date,worddate20.)
D.ship_note=input(.....)
我选了错误答案B,
2.

5 1
4 6
5 4
data one two other;
if x ge 5 then output one;
else if y le 5 then output two;
else output other;
How many obs in dataset one, two and other?
毫不犹豫选了553.....后来回忆起来发现跟原题是不一样的....
3.
file:
Num xxx
33 123

1 342

set file;
