I need to code this in assembly language. I am using Pep$/9$ to code. Start a program that will ask for a starting value then ask for a command of either $\text{'}$M$\text{'}$ or $\text{'}$D$\text{'}.$ The program should then print the value $*2($asla$)$ if $\text{'}$M$\text{'}$ or value $/2($asra$)$ if $\text{'}$D$\text{'}($or not $\text{'}$M$\text{'}).$ Then stop. Like so:

Value? $123$

M or D: M

$246$

Run it again to have:Value? $37$

M or D: D

$18$

You can use the labels charIn and charOut to input and output a character.
