这两道题是同一类型,考Numeric to Character conversion
但是80题的答案是以 default numeric variable 不能超过8bytes为标准
81题就以format格式里的长度为标准了
那究竟按什么标准来确定新转换过来的变量值呢,default长度标准还是括号里format
的长度标准
谢谢。
题目如下:
80
data work.month;
date = input('13mar2000', date9.);
run;
which one represents the type and length of the vatiable date:
A numeric, 8 bytes
B numeric, 9 bytes
答案A
81
data work.month;
date = put('13,mar2000'd,ddmmyy10);
run;
which one represents the type and length of the vatiable date:
C character, 8 bytes
D character, 10 bytes
答案 D |
