1. Write a machine-language program to add the three numbers 2, 3, and 6 and output the sum on the output device. Write it in a format suitable for the loader and execute it on the Pep/8 simulator.

Note that one of the numbers you are asked to add is negative.

IT IS WRONG if you put a positive number in memory and then subtract it. Put the NEGATIVE number in memory and add.

2. Write a machine-language program to input a number, multiply it by 2, and output the result on the output device. Write it in a format suitable for the loader and execute it on the Pep/8 simulator.

3. Write a machine-language program to input a number, divide it by 4, and output the result on the output device. Write it in a format suitable for the loader and execute it on the Pep/8 simulator.

Note: you will get integer division, so 3 divided by 4 is 0, and 5 divided by 4 is 1.

4. Write a machine-language program to input 4 upper case characters, convert them to lower case, and output the result on the output device. Write it in a format suitable for the loader and execute it on the Pep/8 simulator.

Note: you do not need to check that they are alphabetic characters, just assume they are.

upload the pepo files separately- you don't need to zip the 3 files, nor do you need to zip the individual pepo files (it isn't like NetBeans, its just one file for each question).
