我是看了online tutor之后开始做130题的,用的是CxTerm同学排版后的三套仿真界面
pdf版,发现
好多题目里面的statement和function在tutorial里都没提到过啊,作得真郁闷。。。
有一题问:
What is the result of including _TEMPORARY_ keyword option on an ARRAY
statement?
答案是A:the values in the array are automatically retained.
我严重怀疑应该是B啊:the values are written to temporary variables in the
PDV.
还有一题:
Given the following OPTIONS statement:
LIBNAME A 'SAS library reference';
LIBNAME F 'SAS library reference';
OPTIONS FMTSEARCH=(A F.X);
what is the second location searched for formats?
答案是C:WORK.FORMATS
可是我看tutorial里说的很清楚,SAS搜索的顺序是1)WORK.FORMATS 2)LIBRARY.
FORMATS
3)A.FORMATS 4)F.X啊,可是选项里还没有这个LIBRARY.FORMATS。
请大家帮我看看吧,ADV怎么比BASE难这么多呢,郁闷,先谢谢了
