A,B Correct answer
Explanation

EXPOSE is used with PROCEDURE to selectively allow specific variables to be shared between the main program and the procedure, overriding the default local scope. Options A and B are correct: EXPOSE allows variables A through n to be shared, and it is used with PROCEDURE instruction. Option C is incorrect as EXPOSE enables sharing, doesn't suppress it.
