True/ False

2. The SAHF instruction copies the CPU status flags to the AH register.

True/False

3. The Overflow flag will never be set when subtracting a positive integer from a negative integer.

True/False

4. When you move a 16-bit constant or an 8-bit constant into a 64-bit register, the upper bits of the destination operand are cleared.

True/False

5. The MOVSX instruction can use a variable as the source operand.
