Global statements do not apply to a DATA stepview. Global statements such as theFILENAME, FOOTNOTE, LIBNAME, OPTIONS, and TITLE statements, even if included inthe DATA stepthat created the SAS view, have noeffect on the SAS view. If you doinclude global statements in your source program statements, SAS stores the DATA stepview but not the global statements.When the view is referenced, actualexecution can differ from the intended execution.
所以答案是C,因为infile rawdata中的rowdata是一个filename,不能被应用到data step view中。
如果rowdata是一个带引号的标准路径引用(比如:infile 'd:\rowdata.txt'),那就要选B了
