and its operation code is E

0 .

You will need to include this XDUMP in your own program to check that your program storage is exactly the same as the above assembled program. The register contents are not dumped but you should not need them to complete this assignment. You will have to decode instructions with explicit addressing as you do not know the names of the variables. To clarify, you will disassemble what you see in the assembled program provided above, you will type the decoded instructions into the program shell provided above and then, finally, you will run the program to be sure that it assembles correctly and that your XDUMP'd program storage matches the assembled program provided above EXACTLY.
