请教一下SAS ADVANCED 130 第99题:
99. 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?
A.F.X
B.A.FORMATS
C.WORK.FORMATS
D.SAS supplied formats
请问为什么答案选C,书上不是说最先检索work. formats吗?如果不是,那么真正的顺序又是什么呢?
谢谢!
