libname temp ‘abc.sds.as’; data temp.X1; set sasuser.X2; run; Which is the correct statement??

  1. In datastep input is read from temporary location and output is written to temporary location.

  2. .) In datastep input is read from permanent location and output is written to temporary location.

  3. In datastep input is read from temporary location and output is written to permanent location.

  4. In datastep input is read from permanent location and output is written to permanent location.

D Correct answer
Explanation

The code reads from sasuser.X2 (a permanent library) and writes to temp.X1 in 'abc.sds.as' (also a permanent location, as indicated by the libname statement). Therefore, both input is read from a permanent location and output is written to a permanent location.

AI explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) In datastep input is read from temporary location and output is written to temporary location. This option is incorrect because the LIBNAME statement libname temp ‘abc.sds.as’; specifies the library temp as a permanent location, not a temporary location.

Option B) In datastep input is read from permanent location and output is written to temporary location. This option is incorrect because the LIBNAME statement libname temp ‘abc.sds.as’; specifies the library temp as a permanent location, not a temporary location. Additionally, the output dataset temp.X1 is stored in the library temp, which is a permanent location.

Option C) In datastep input is read from temporary location and output is written to permanent location. This option is incorrect because the LIBNAME statement libname temp ‘abc.sds.as’; specifies the library temp as a permanent location, not a temporary location. Additionally, the output dataset temp.X1 is stored in the library temp, which is a permanent location.

Option D) In datastep input is read from permanent location and output is written to permanent location. This option is correct because the LIBNAME statement libname temp ‘abc.sds.as’; specifies the library temp as a permanent location. The input dataset sasuser.X2 is read from a permanent location (the sasuser library), and the output dataset temp.X1 is written to a permanent location (the temp library).

The correct answer is D) In datastep input is read from permanent location and output is written to permanent location.
