The Shift function moves the bits in an integer to the left or to the right. Note that any bit shifted out cannot be recovered.

• Operand A: contains the value to be shifted.

• Operand B: contains the number of bits to be shifted (one or more).

The Shift function may be performed on values contained in the following operands:

• Memory Integer (MI)

• Memory Long Integer (ML)

• Double Word (DW)
