SHL/SAL : Shift logical/Arithmetic Left: These instructions shift the operand byte or word bit by bit to the left and insert 0 in the newly introduced least significant bits. In case of all the ROTATE and SHIFT instructions, the count is either 1 or specified by register CL. The operand might reside in a register or a memory location but can't be an immediate data. All flags are affected depending on the result. Given figure describe the execution of this instruction. It is to be considering here that the shift operation is through carry flag.
