Question

To disassociate a libref that you previously assigned, you can use the UNASSIGN option in the LIBNAME statement.

a. True
b. False

Answer 1

The statement is false; the correct SAS syntax to disassociate a libref previously assigned is to use the CLEAR option in the LIBNAME statement, not UNASSIGN. b. False

Step-by-step explanation:

To disassociate a libref that you previously assigned in SAS, you can use the CLEAR option in the LIBNAME statement, not the UNASSIGN option. Therefore, the correct answer is b. False. The LIBNAME statement with the CLEAR option is used like this:

LIBNAME libref CLEAR;

By issuing this statement, SAS disassociates the libref from the previously assigned library, freeing it up for use with other libraries or simply removing it from the current session.
