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

我觉得是第一个是work。formats，第二个是library.formats，然后3，4是 A，f。x
谁知道到底是什么，谢谢

The WORK.FORMATS catalog is always searched first, and the LIBRARY.FORMATS catalog is searched next, unless one of them appears in the FMTSEARCH= list.

If a catalog appears in the FMTSEARCH= list, the catalog is searched in the order in which it appears in the list. If a catalog in the list does not exist, that particular item is ignored and searching continues.
